At the heart of ULTIMA is a dual feed-forward error correction architecture where two amplifiers work in tandem: the main amplifier generates the signal and power, while the second monitors and corrects errors in real time. The result is consistent distortion performance regardless of output load, keeping THD at 0.02% whether driving headphones or speakers.\u003c\/p\u003e\n\n\u003cp\u003eThis trickle-down from Chord's high-end amplifier range (the same basic topology powers the \u003ca href=\"\/products\/chord-electronics-etude\"\u003eEtude\u003c\/a\u003e at $7,165 and the \u003ca href=\"\/products\/chord-electronics-ultima-2\"\u003eUltima 2\u003c\/a\u003e mono blocks at $61,000) means the Anni inherits a level of amplification refinement that its compact size and price do not suggest. The single-ended Class AB sliding bias design feeds both headphone and speaker outputs, switching automatically when headphones are plugged in.\u003c\/p\u003e\n\n\u003ch5\u003eHeadphone Amplifier\u003c\/h5\u003e\n\u003cp\u003eThe Anni treats headphone amplification as a primary function, not an afterthought. Both a 3.5mm and a 6.35mm jack sit on the front panel, and they can be used simultaneously for shared listening. Output drops from the full 10W speaker rating to approximately 3W at 32 ohms and 500mW at 300 ohms, which is more than enough for planar magnetics and high-impedance dynamic headphones.\u003c\/p\u003e\n\n\u003cp\u003ePlugging headphones in automatically mutes the speaker outputs and changes the power indicator from cyan to green. No button press required. The volume control on the front panel works identically for both outputs, and Chord's circuit ensures the same low-noise, low-distortion signal path whether you are driving speakers or cans.\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\/anni_rear_inline.jpg?v=1773417142?v=1773170267\" alt=\"Chord Electronics Anni rear panel with RCA inputs, speaker terminals, and DC output\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\n\u003c\/p\u003e\n\n\u003ch5\u003eDesktop Power Management\u003c\/h5\u003e\n\u003cp\u003eThe Anni ships with a 15V external switching power supply that connects via a 4-pin socket on the rear. What makes this power supply clever is the DC pass-through output on the Anni itself. Connect the included 5V conversion kit (a short USB-A to micro-USB cable and a voltage adapter) and the Anni feeds power directly to the Qutest DAC. Add the Huei phono stage and the Anni's DC out handles that too. Three components, one wall plug, one power supply brick.\u003c\/p\u003e\n\n\u003cp\u003eThis shared power architecture is not just convenient. It eliminates the noise that can come from multiple switching power supplies running on the same circuit, and it reduces the cable clutter that makes desktop audio systems look like a science experiment gone wrong.\u003c\/p\u003e\n\n\u003ch5\u003eSpeaker Amplification\u003c\/h5\u003e\n\u003cp\u003eThe rear-panel 4mm banana plug sockets connect the Anni directly to compact loudspeakers.

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 \u003ca href=\"\/products\/chord-electronics-dave\"\u003eDAVE\u003c\/a\u003e, every product runs code that Chord wrote themselves.\u003c\/p\u003e\n\n\u003ch5\u003eWhy an Ultima Integrated Exists\u003c\/h5\u003e\n\u003cp\u003eMost manufacturers put their best technology in separates and offer integrated amplifiers as a compromise. Chord went the other direction. The Ultima Integrated uses the same dual feed-forward error correction circuit found in the \u003ca href=\"\/products\/chord-electronics-ultima-6\"\u003eUltima 6\u003c\/a\u003e and \u003ca href=\"\/products\/chord-electronics-ultima-5\"\u003eUltima 5\u003c\/a\u003e power amplifiers. The preamp section shares its design philosophy with the \u003ca href=\"\/products\/chord-electronics-ultima-pre-3\"\u003eUltima Pre 3\u003c\/a\u003e. The difference is packaging: one box instead of two, with a shared power supply and shorter internal signal paths. For a system built around a single source (a Chord DAC, a streamer, a CD transport), the Integrated eliminates the interconnect between preamp and power amp entirely.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/chord-ultima-integrated-side.jpg\" alt=\"Chord Electronics Ultima Integrated amplifier side view\" style=\"max-width: 100%;\"\u003e\u003c\/p\u003e\n\n\u003ch5\u003eULTIMA Topology at 125 Watts\u003c\/h5\u003e\n\u003cp\u003eThe dual feed-forward error correction circuit monitors and corrects the output signal at two points in the amplification chain, catching distortion that single-loop feedback designs miss. At 125 watts per channel into 8 ohms, the Ultima Integrated has enough power for most speakers in typical listening rooms. The 16 proprietary MOSFET output transistors are closely matched between channels, maintaining stereo imaging accuracy even at high output. This is not a stripped-down version of the ULTIMA circuit. It is the same topology with a power output scaled to what an integrated amplifier reasonably needs.\u003c\/p\u003e\n\n\u003ch5\u003eAV Bypass and Pre-Out\u003c\/h5\u003e\n\u003cp\u003eThe AV bypass input lets a home theater processor pass signal through the Ultima Integrated directly to the power amplifier section, skipping volume control. When the system switches to music, the Integrated takes over. The pre-out on the rear panel lets you add a separate power amplifier if you outgrow the internal 125 watts, turning the Integrated into a preamplifier feeding an Ultima 6 or Ultima 5 while keeping the same source switching and volume control.\u003c\/p\u003e\n\n\u003ch5\u003eChord Electronics Ultima Integrated Power Supply\u003c\/h5\u003e\n\u003cp\u003eChord's proprietary high-frequency switch-mode power supply delivers current to the amplifier stages faster than conventional toroidal designs. The SMPS operates above the audio band, so its switching frequency cannot interfere with the signal. In an integrated amplifier where the preamp and power amp share a chassis, keeping power supply noise out of the sensitive preamp stages matters even more than in separates. Chord's approach isolates the power delivery from the audio signal by frequency, not just by physical distance.\u003c\/p\u003e\n\n\u003ch5\u003eThe ULTIMA Range\u003c\/h5\u003e\n\u003cp\u003eThe Ultima Integrated is the simplest path into ULTIMA-level amplification. For those who want separates, the Ultima Pre 3 preamplifier and Ultima 6 power amplifier provide the same technology with more flexibility and upgrade potential. All ULTIMA products share the dual feed-forward topology and proprietary MOSFET output stage, designed and built in Kent, England.

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 \u003ca href=\"\/products\/chord-electronics-dave\"\u003eDAVE\u003c\/a\u003e, every product runs code that Chord wrote themselves.\u003c\/p\u003e\n\n\u003ch5\u003eULTIMA Topology in a Compact Package\u003c\/h5\u003e\n\u003cp\u003eThe Alto borrows directly from Chord's ULTIMA power amplifier architecture, specifically the dual feed-forward error correction circuit that defines their flagship mono blocks. Where the \u003ca href=\"\/products\/chord-electronics-anni\"\u003eAnni\u003c\/a\u003e uses a similar topology at lower power for the \u003ca href=\"\/products\/chord-electronics-qutest\"\u003eQutest\u003c\/a\u003e range, the Alto scales that circuit to professional output levels. In most amplifier designs, feedback is applied after the output stage to reduce distortion. Chord's approach applies correction at two separate points in the signal path, catching errors that traditional single-loop designs miss. The result is measurably lower distortion at real-world power levels, not just on a test bench at 1 watt.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/alto_angle_inline.jpg?v=1773417140?v=1773252047\" alt=\"Chord Electronics Alto showing volume control and illuminated status orbs\" style=\"max-width: 100%; height: auto;\"\u003e\u003c\/p\u003e\n\n\u003ch5\u003eHeadphone Outputs for Every Connector\u003c\/h5\u003e\n\u003cp\u003eFour headphone jacks cover every standard in professional and consumer use. The 4.4mm Pentaconn balanced output handles high-end planar magnetic headphones that benefit from balanced drive. The two 6.35mm outputs serve studio cans and most high-impedance dynamic headphones. The 3.5mm jack works with IEMs and portable headphones without an adapter. At 2,250mW into 100 ohms from the balanced output, the Alto has enough current to drive demanding loads that choke lesser desktop amps.\u003c\/p\u003e\n\n\u003ch5\u003eAlto as a Speaker Amplifier\u003c\/h5\u003e\n\u003cp\u003eThis is not a headphone amp with speaker taps bolted on as an afterthought. The Alto delivers a genuine 50 watts per channel into 4 ohms through 4mm banana binding posts, enough to drive efficient bookshelf speakers or nearfield studio monitors to serious levels in a desktop or small room setup. The ULTIMA topology maintains its grip and control at speaker-level power, making this a legitimate integrated solution for anyone running both headphones and speakers from the same source.\u003c\/p\u003e\n\n\u003ch5\u003ePreamp and System Integration\u003c\/h5\u003e\n\u003cp\u003eBalanced XLR inputs accept signal from any professional DAC or source component, including the \u003ca href=\"\/products\/chord-electronics-hugo-tt2\"\u003eHugo TT2\u003c\/a\u003e or Qutest. RCA inputs accommodate consumer-level gear. The XLR preamp outputs let you feed active studio monitors or a separate power amplifier, turning the Alto into a preamp\/headphone amp in a larger system.
