Output stages use premium transistors or tubes with thermal management designed for sustained high-power operation.

In a stereo amplifier, both channels draw from shared power supply resources, which means a dynamic peak in one channel can momentarily starve the other. When bass drums hit in the left channel, the right channel's string sustain can compress slightly. In a monoblock design, each channel has its own dedicated power supplies, its own transformer reserves, and its own current delivery path. The DragoN Monoblocks take this further by housing three separate linear supplies in each chassis: one for the tube input stage, one for the N-Core output module's power rail, and one for auxiliary circuits. With six total power supplies across the pair, there is zero shared infrastructure between channels.\u003c\/p\u003e\n\n\u003ch5\u003eThe tubeD Hybrid Architecture\u003c\/h5\u003e\n\u003cp\u003eThe DragoN Monoblocks use the same proprietary tubeD circuit found in the \u003ca href=\"\/products\/rogue-audio-dragon-power-amplifier\"\u003eDragoN stereo amplifier\u003c\/a\u003e, with each monoblock containing a matched pair of 12AU7 tubes integrated into the gain structure ahead of the Hypex N-Core output module. The tubes handle voltage amplification and impose their harmonic character on the signal, while the N-Core module delivers the current and damping factor needed to control loudspeaker drivers with precision. Unlike simple tube buffer designs, the tubeD topology makes the tube section a functional part of the amplifier's gain chain, meaning the sonic contribution of the tubes is substantive rather than cosmetic.\u003c\/p\u003e\n\n\u003ch5\u003eDragoN Stereo vs. DragoN Monoblock\u003c\/h5\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/rogue-audio-dragon-power-amplifier\"\u003eDragoN stereo amplifier\u003c\/a\u003e delivers 300W\/8 ohms and 500W\/4 ohms from a single chassis with three power supplies shared across both channels.

Unlike many tube amplifiers that require powering down to change modes, the M-180's switch operates during playback, letting you match the amplifier's character to the music in real time. Ultralinear mode delivers the full authority the M-180 is capable of, with tight bass control and explosive dynamics. Triode mode shifts the emphasis toward midrange liquidity and spatial depth, making it a natural choice for acoustic recordings, vocals, and late-night listening at lower levels.\u003c\/p\u003e\n\u003cdiv style=\"text-align: center; margin: 20px 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/m180_inline_silver_front.jpg?v=1774405527\" alt=\"Rogue Audio M-180 monoblock silver finish showing machined aluminum faceplate and tube cage\" style=\"display: block; margin-left: auto; margin-right: auto; border-radius: 15px; max-width: 100%; width: 938px;\" loading=\"lazy\"\u003e\u003c\/div\u003e\n\n\u003ch5\u003ePower Supply and Output Transformers\u003c\/h5\u003e\n\u003cp\u003eEach M-180 monoblock contains a massive high-capacity power supply dedicated entirely to its own output stage, with no power sharing between channels. The energy reserves in each supply are designed to handle sustained low-frequency demands without voltage sag, keeping the output stage in its linear operating region even during the most punishing bass passages. The ultra-wide bandwidth output transformers are custom wound to achieve frequency response from 5Hz to 50kHz (±1dB), well beyond the audible range, ensuring phase accuracy and transient response that approaches the best solid-state designs. These transformers are mechanically isolated from the chassis to prevent vibration from coupling into the signal path.\u003c\/p\u003e\n\n\u003ch5\u003eBalanced Connectivity\u003c\/h5\u003e\n\u003cp\u003eEach M-180 accepts both balanced (XLR) and single-ended (RCA) connections with heavy-duty gold-plated connectors. The balanced inputs make the M-180 particularly well-suited to monoblock placement near speakers, where long interconnect runs between preamplifier and amplifier benefit from balanced cable's common-mode noise rejection. This setup also allows you to use shorter, higher-quality speaker cables while running longer, less expensive XLR interconnects from your preamp. The RP-7 v2 and RP-9 v2 preamplifiers both offer balanced outputs for a fully balanced Rogue signal path.\u003c\/p\u003e\n\u003cdiv style=\"text-align: center; margin: 20px 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/m180_inline_rear_panel.jpg?v=1774405523\" alt=\"Rogue Audio M-180 monoblock rear panel showing KT120 output tubes, XLR and RCA inputs, and speaker binding posts\" style=\"display: block; margin-left: auto; margin-right: auto; border-radius: 15px; max-width: 100%; width: 938px;\" loading=\"lazy\"\u003e\u003c\/div\u003e\n\n\u003ch5\u003e\"Dark\" Version\u003c\/h5\u003e\n\u003cp\u003eThe M-180 Dark ($9,495\/pair) applies Rogue's most comprehensive upgrade package to the already well-specified standard amplifier:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Power Supply:\u003c\/strong\u003e 33% larger power supply with Hex Fred high-speed diodes and polypropylene bypass capacitors for increased energy storage and faster recovery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Coupling Capacitors:\u003c\/strong\u003e Ultra-premium coupling capacitors in the signal path for maximum transparency\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpgraded Tube Complement:\u003c\/strong\u003e Premium matched octets of KT120 output tubes and upgraded small-signal tubes from Psvane, Telefunken, or RCA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCardas Rhodium Connections:\u003c\/strong\u003e Heavy-duty gold-plated XLR and RCA inputs with Rhodium binding posts from Cardas Audio\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNude Vishay Resistors:\u003c\/strong\u003e Precision resistors in critical input stages for lower noise and greater signal purity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 33% power supply increase in the Dark version is the largest of any Rogue Dark upgrade, reflecting the M-180's higher power demands and the benefits of additional energy reserves at this performance level.\u003c\/p\u003e\n\n\u003ch5\u003eExplore the Full Rogue Audio Power Amplifier Lineup\u003c\/h5\u003e\n\u003cp\u003eThe M-180 Monoblocks are Rogue's flagship pure tube power amplifiers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003ca href=\"\/products\/rogue-audio-stereo-100-amplifier\"\u003eStereo 100\u003c\/a\u003e\u003c\/strong\u003e - 100W pure tube stereo with Mundorf EVO Oil caps and ultra-wide bandwidth transformers.

This dual-output switch-mode power supply with Active Power Factor Correction (APFC) is rated at 1,500 watts and is approximately 5% more efficient than passive linear alternatives. An innovative dual-connection cable system ensures that the four amplifier modules receive uniform current via the shortest possible path, eliminating voltage drops that could compromise channel-to-channel consistency. Soft-clipping circuitry provides graceful protection at the limits of output, preventing hard clipping artifacts even during the most demanding passages. Power consumption sits at 350W during operation and less than 0.5W in standby.\u003c\/p\u003e\n\u003ch5\u003eBridged Operation and System Flexibility\u003c\/h5\u003e\n\u003cp\u003eEach pair of the A35.8's eight channels can be bridged to create four channels of substantially higher output. In bridged mode, each pair delivers up to 740W into 8 ohms, 750W into 4 ohms, and 450W into 2 ohms, providing the kind of current delivery that can control even the most demanding speaker loads. This flexibility means the A35.8 can serve as an eight-channel amplifier for a 7.1 surround system, a four-channel bridged amplifier for a high-power stereo bi-amp configuration, or any combination in between. THD+N measures 0.005% at 10W into 8 ohms across 20Hz to 20kHz, frequency response is flat within 0.2dB\/-0.5dB, and signal-to-noise ratio exceeds 115dB.\u003c\/p\u003e\n\u003ch5\u003eExplore More Primare Products\u003c\/h5\u003e\n\u003cp\u003eComplete your 35 Series system with these companion components:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-i35-modular-integrated-amplifier\"\u003ePrimare I35\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-pre35-modular-preamplifier\"\u003ePrimare PRE35\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-a35-2-power-amplifier\"\u003ePrimare A35.2\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-r35-mm-mc-phono-preamplifier\"\u003ePrimare R35\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-cd35-cd-player\"\u003ePrimare CD35\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-dd35-cd-transport\"\u003ePrimare DD35\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-spa25-prisma-home-cinema-integrated-amplifier\"\u003ePrimare SPA25 Prisma\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/primare-prisma-sp25-home-cinema-processor\"\u003ePrimare SP25 Prisma\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eThe Listening Room Difference\u003c\/h5\u003e\n\u003cp\u003eWe're a third-generation family business with a brick-and-mortar showroom in Chestertown, Maryland, and a reputation built on trust, not hype.

Each channel employs ten high-power ONSEMI transistors arranged in a parallel push-pull configuration. This multi-triode design operates in a high-bias state, which dramatically lowers the output impedance and provides an immense reserve of current. This allows the MA-1 to maintain an iron grip on the speaker drivers, delivering lightning-fast transients and deep, textured bass while preserving the subtle micro-details that bring music to life.\u003c\/p\u003e\n\u003ch5\u003eA Reservoir of Surging Power\u003c\/h5\u003e\n\u003cp\u003eThe foundation of the MA-1’s performance is its colossal, dual-mono power supply. Two independent, oversized transformers provide a total of 1250VA of power, with separate windings for the left and right channels. This raw power is smoothed by a massive capacitor bank totaling 190,000µF, composed of multiple smaller capacitors connected in parallel. This design offers a significantly lower equivalent internal resistance (ESR) than a single large capacitor, ensuring that the amplifier can respond instantaneously to the most demanding musical peaks without strain or compression.\u003c\/p\u003e\n\u003ch5\u003eUnparalleled System Flexibility\u003c\/h5\u003e\n\u003cp\u003eThe MA-1 is not a single amplifier, but three distinct amplifiers in one. In \u003cb\u003eStereo Mode\u003c\/b\u003e, it functions as a classic, high-performance two-channel amplifier. In \u003cb\u003eBridged Mode\u003c\/b\u003e, two MA-1 units work together to deliver immense power for speakers with demanding power requirements. In \u003cb\u003eMono Mode\u003c\/b\u003e, two amplifiers are used to drive the left and right channels independently, offering the ultimate in channel separation and providing an ideal solution for high-end speakers that support bi-wiring or bi-amping. This incredible versatility ensures the MA-1 can adapt and excel in any system configuration.\u003c\/p\u003e\n\u003ch5\u003eThe Art of Mechanical Grounding\u003c\/h5\u003e\n\u003cp\u003eThe MA-1 introduces the innovative H-shaped chassis, a core element of the M-series design language. A 20mm thick, CNC-machined aluminum plate forms the central beam of the structure, acting as a mechanically grounded core for the entire amplifier. All components are mounted to this central beam, creating isolated cavities that shield different circuit modules from each other. The left and right channel circuits are arranged symmetrically on either side of the beam, ensuring a perfectly balanced layout that minimizes interference and provides a foundation of unshakable stability.\u003c\/p\u003e\n\u003ch5\u003eSilent, Intelligent Cooling\u003c\/h5\u003e\n\u003cp\u003eManaging the thermal output of a high-bias amplifier is critical. The MA-1 employs an intelligent, silent cooling system. Two sensors continuously monitor the heatsink temperatures. When a preset value is exceeded, an ultra-quiet 7.4\" fan automatically activates, dynamically adjusting its speed based on the thermal load. The fan is housed within an isolated duct, ensuring no electronic components are in the airflow path. This prevents dust accumulation and guarantees that the cooling system is virtually inaudible, even during quiet passages or at low listening volumes.\u003c\/p\u003e\n\u003ch5\u003eExplore the Matrix Audio 1-Series\u003c\/h5\u003e\n\u003cp\u003eThe Matrix Audio 1-Series is a complete flagship system, designed and voiced to work together.

Dual feed-forward error correction continuously monitors the electrical and thermal performance of every MOSFET power device in the output stage, correcting nonlinearities before they reach the speaker terminals. Each amplifier channel has two independent error correction pathways, each one compensating for distortion products at the power devices in real time.\u003c\/p\u003e\n\n\u003cp\u003eThis topology was originally theorized by Professor Malcolm J. Hawksford and developed in compact form by Robert Cordell. Chord founder John Franks adapted it for the company's proprietary MOSFET designs, and the BerTTi is the latest implementation. The result is measurably low distortion without the feedback-related compromises that plague conventional correction schemes.\u003c\/p\u003e\n\n\u003ch5\u003eChord Electronics BerTTi Power Supply Design\u003c\/h5\u003e\n\u003cp\u003eTwin switched-mode power supplies feed the output stage, and a separate 400kHz super low noise auxiliary supply boosts the front-end voltage rails above the main rails. This gives the BerTTi more headroom for dynamic transients than its 75-watt rating might suggest. The higher auxiliary rail voltage means the input stage can swing further before clipping, preserving signal integrity on peaks that would compress a simpler design. Four internal fans keep operating temperatures low enough for placement in enclosed cabinets or tight desktop stacks.\u003c\/p\u003e\n\n\u003ch5\u003eInputs and System Integration\u003c\/h5\u003e\n\u003cp\u003eThe rear panel carries balanced XLR and unbalanced RCA inputs, two pairs of high-current speaker binding posts, a 12V trigger input, and an IEC mains connector with master power switch. The single front-panel polycarbonate sphere serves as the power switch, glowing to indicate operating state. The BerTTi is designed primarily as the power section for the Hugo TT2, which functions as DAC, preamplifier, and headphone amp in one chassis. Feed it balanced XLR from the TT2's outputs and the system is complete.\u003c\/p\u003e\n\n\u003cp style=\"text-align: center; margin: 20px 0;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/bertti_rear_inline.jpg?v=1773417144?v=1773168546\" alt=\"Chord Electronics BerTTi rear panel showing balanced XLR and RCA inputs, speaker binding posts, and 12V trigger\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\n\u003c\/p\u003e\n\n\u003ch5\u003eBuilding the Complete Table Top System\u003c\/h5\u003e\n\u003cp\u003eThe BerTTi matches the Table Top dimensions at 235mm wide, stacking with the Hugo TT2 and Hugo M Scaler.

While every other manufacturer buys off-the-shelf DAC chips, Rob Watts designs custom FPGA algorithms with tap lengths that dwarf anything from ESS or AKM. Their proprietary Pulse Array technology, MOSFET amplification stages, and high-frequency switch-mode power supplies are all designed and built in Kent, England. From the portable \u003ca href=\"\/products\/chord-electronics-mojo-2\"\u003eMojo 2\u003c\/a\u003e to the flagship DAVE, every product runs code that Chord wrote themselves.\u003c\/p\u003e\n\n\u003ch5\u003eULTIMA Technology in the Choral Range\u003c\/h5\u003e\n\u003cp\u003eThe Etude borrows its amplifier topology directly from Chord's ULTIMA reference power amplifiers. Dual feed-forward error correction monitors and corrects the output signal at two points in the circuit, catching distortion that single-loop feedback designs miss. This is not a marketing label applied to a standard Class AB circuit. The error correction amplifier runs alongside the main signal amplifier, comparing the output against the input in real time and correcting deviations before they reach your speakers. At 80 watts per channel, the Etude has enough power for most bookshelf and floorstanding speakers in typical listening rooms.\u003c\/p\u003e\n\n\u003ch5\u003eChord Electronics Etude Power Supply\u003c\/h5\u003e\n\u003cp\u003eWhere most amplifiers use toroidal transformers operating at 50-60 Hz, the Etude's switch-mode power supply runs at frequencies above the audio band entirely. Chord's custom SMPS design charges its capacitors up to 20,000 times per second, delivering current on demand faster than a conventional transformer can respond. The result is tighter bass control and better dynamic response, particularly on transient-heavy material where the amplifier needs to deliver sudden bursts of current to the loudspeakers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/etude-top-inline.jpg?v=1773253932\" alt=\"Chord Electronics Etude top view showing ventilation and internal blue LED glow\" style=\"max-width: 100%; height: auto;\"\u003e\u003c\/p\u003e\n\n\u003ch5\u003eMOSFET Output Stage\u003c\/h5\u003e\n\u003cp\u003eThe Etude uses Chord's proprietary MOSFET output transistors, custom-designed and closely matched between left and right channels. Off-the-shelf MOSFETs vary in characteristics from unit to unit.

This pairing works particularly well with the Prima preamplifier and DAVE as a source, creating a full Choral-range system with no compromises in amplification. Balanced XLR connections between components allow long cable runs without signal degradation, so the Etude can sit close to the speakers while the source components remain across the room.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/etude_lifestyle_inline.jpg?v=1773678249\" alt=\"Chord Electronics Etude power amplifier in a listening room system\" style=\"width: 100%; height: auto; max-width: 938px; border-radius: 4px;\"\u003e\u003c\/p\u003e\n\u003ch5\u003eThe Choral Range\u003c\/h5\u003e\n\u003cp\u003eThe Etude is part of Chord's Choral range, sharing its form factor with the DAVE, Prima, Symphonic, and \u003ca href=\"\/products\/chord-electronics-choral-ensemble-stand\"\u003eChoral Ensemble Stand\u003c\/a\u003e.

The wideband amplifier design maintains phase integrity from well below the audible range to well above it, so the sound stays clean and coherent at any volume.\u003c\/p\u003e\n\n\u003ch5\u003eStereo and Mono Operation on the Cyrus 80 PWR\u003c\/h5\u003e\n\u003cp class=\"p3\"\u003eA rear-panel switch lets you configure the 80 PWR for stereo or bridged mono operation. In stereo mode, you get 200 watts per channel from a single unit. Switch to mono and the amplifier bridges its two channels into one, delivering 300 watts to a single speaker. This is a practical upgrade path: start with one 80 PWR in stereo, and when you're ready for more power, add a second unit so each speaker gets its own dedicated 300-watt monoblock. The balanced XLR inputs support either configuration cleanly.\u003c\/p\u003e\n\n\u003cdiv style=\"text-align: center; margin: 24px 0;\"\u003e\u003cimg style=\"max-width: 100%;\" alt=\"Cyrus 80 PWR rear panel showing XLR inputs, bridge\/stereo switch, and speaker binding posts\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/cyrus-80-pwr-rearpanel.jpg?v=1773166220\"\u003e\u003c\/div\u003e\n\n\u003ch5\u003eSpeaker Control\u003c\/h5\u003e\n\u003cp class=\"p3\"\u003eThe 80 PWR is designed to drive speakers that need current and control. Planar magnetics, large floorstanders, and low-impedance designs all benefit from an amplifier with the power supply reserves to maintain damping factor across the frequency range. The 200-watt stereo rating is continuous, not peak, and the over-specified power supply means the amplifier doesn't run out of headroom before the volume knob does. If your speakers are rated for 4 ohms or have complex crossovers that dip below their nominal impedance, this kind of reserve matters.\u003c\/p\u003e\n\n\u003ch5\u003ePaired with the Cyrus 80 PRE\u003c\/h5\u003e\n\u003cp class=\"p3\"\u003eThe 80 PWR was designed to partner with the \u003ca href=\"\/products\/cyrus-80-pre-streaming-preamplifier\"\u003eCyrus 80 PRE\u003c\/a\u003e. The PRE handles all source management (BluOS streaming, DAC, phono, HDMI eARC) and sends a clean balanced signal via XLR to the PWR for amplification. Separating the preamp and power amp into dedicated chassis reduces interference between the sensitive analog circuits and the high-current output stage. The result is a lower noise floor and more precise imaging than you'll get from a single integrated unit, especially at lower listening levels where noise becomes more apparent.\u003c\/p\u003e\n\n\u003cdiv style=\"text-align: center; margin: 24px 0;\"\u003e\u003cimg style=\"max-width: 100%;\" alt=\"Cyrus 80 PWR Power Amplifier in living room media setup\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/cyrus-80-pwr-carousel3.jpg?v=1773166218\"\u003e\u003c\/div\u003e\n\n\u003ch5\u003eBuild Your Cyrus System\u003c\/h5\u003e\n\u003cp class=\"p3\"\u003eThe 80 PWR pairs with the \u003ca href=\"\/products\/cyrus-80-pre-streaming-preamplifier\"\u003eCyrus 80 PRE\u003c\/a\u003e for a separates system with streaming, or with any balanced preamplifier.
