The P75 Mk4 is always enjoyable thanks to good timing and strong bass allied to good low level resolution, the fingers on tabla of Patricia Barber's 'Constantinople' are very finely resolved and contrast superbly with the tension produced by the electric guitar. The P75 Mk4 is a bit more pricey than it used to be, what isn't, but it delivers sound quality that's fully commensurate with that asking price. What's more it's a great partner for any cartridge not just those from the same company as the Apheta 2 proves, especially when you set it up in PE mode which is undoubtedly it's strongest suit.

Dynavector P75 Mk4 Phono Preamplifier
Regular price

Unit price
The Dynavector P75 Mk4 is a compact, full-featured MM/MC phono preamplifier with five selectable gain settings (40dB to 63dB), six impedance options, three capacitance settings, and Dynavector's proprietary Phono Enhancer (PE) mode. The two-piece design separates the audio circuit from the new ultra-low-noise switching power supply introduced in the Mk4, keeping electrical interference away from the sensitive phono signal path. At 160mm wide and 500 grams, it fits anywhere but performs well beyond its size.
The P75 Mk4 is the natural phono stage partner for any Dynavector cartridge, but it works equally well with cartridges from other manufacturers. The PE mode is what sets it apart from the competition at this price point. Rather than amplifying voltage like a conventional phono stage, PE mode operates as a current amplifier, fundamentally changing how the cartridge interacts with the electronics. Dynavector designed it specifically to extract more from their own MC cartridges, but the results are impressive with any low-output MC. If you're running a Dynavector cartridge and want to hear what it's truly capable of, this is the phono stage to pair with it.
Key Features of the Dynavector P75 Mk4
- Five Gain Settings: 40dB, 46dB, 56dB, 60dB, and 63dB selectable via internal jumpers, accommodating everything from high-output MM cartridges to the lowest-output MC designs.
- Six Impedance Options: 60, 100, 130, 220, 470, and 47,000 ohms, covering the full range of cartridge loading requirements for both MM and MC types.
- Phono Enhancer (PE) Mode: Dynavector's current-drive amplification mode presents a near-zero impedance load to the cartridge, changing the electrical relationship between cartridge and phono stage for improved dynamics and detail.
- Three PE Impedance Ranges: PE mode selectable for 4-10 ohm, 10-20 ohm, and 20-50 ohm cartridge impedances.
- Ultra-Low-Noise Mk4 Power Supply: New in the Mk4, the switching power supply converts the external 12V DC input to dual high voltages with noise levels that are virtually unmeasurable.
- Three Capacitance Settings: 100pF, 200pF, and 300pF input capacitance for fine-tuning MM cartridge response.
- Compact Two-Piece Design: Audio circuit and power supply are physically separated to eliminate electrical interference.
Phono Enhancer (PE) Mode
The P75 Mk4's most distinctive feature is the Phono Enhancer mode, a current-drive amplification topology that Dynavector developed specifically for MC cartridges. In conventional voltage-mode operation, the phono stage presents a load impedance to the cartridge, and the cartridge generates a voltage signal proportional to stylus motion. In PE mode, the amplifier presents a near-zero impedance load, effectively a short circuit, forcing the cartridge to generate a current signal instead. The amplifier then converts this current to voltage before the RIAA equalization stage.
The practical effect is significant: the cartridge's internal impedance becomes the only factor determining the electrical load, eliminating cable capacitance and connector resistance from the equation. This results in improved transient response, greater dynamic range, and more detailed low-level information retrieval. PE mode is available in three impedance ranges (4-10, 10-20, and 20-50 ohms) to match different MC cartridge specifications. Most Dynavector cartridges with 5-6 ohm impedance work optimally in the 4-10 ohm PE setting.
Mk4 Power Supply Improvements
The most significant change in the Mk4 revision is the completely redesigned power supply. The new ultra-low-noise switching design is electrically isolated from the input power, converting the 12V DC from the external adapter into the dual high voltages required by the audio circuit. Power supply noise, which in lesser designs can manifest as hum or a raised noise floor, is reduced to levels that are effectively unmeasurable. The external power supply keeps the transformer and its associated electromagnetic field physically separated from the sensitive phono amplification circuits.
Versatile Loading and Gain Configuration
The P75 Mk4 accommodates virtually any phono cartridge through its comprehensive loading options. MM cartridges run at the standard 47k ohm impedance with selectable capacitance (100, 200, or 300pF) to fine-tune high-frequency response. MC cartridges can be loaded at 60, 100, 130, 220, or 470 ohms in conventional voltage mode, or operated in PE mode for current-drive amplification. Gain is adjustable from 40dB (suitable for high-output cartridges) to 63dB (for the lowest-output MC designs like Dynavector's 0.26mV Te Kaitora Rua). All settings are configured via internal jumpers, accessible by removing the top cover.

What has become apparent to me is that what this "next step up" in natural-ness for me was, is this greater feeling of space between all the instruments and singers, allowing them to breathe in a more natural way. It gave a sense of life to studio recordings and allowed more of the "event" in a live recording to come through, giving music a greater sense of realism. You can spend more, way, way more, and get less, much, much less music for your money than you can with this new MKIV version of the P75. It certainly has no equal for the money, and it may just be one of the top five best bargains you can find for high end audio. Grade: 5.0 / 5.0
Of all the generations of the Dynavector P75, the new MK4 version represents by far the greatest gain in performance and build quality. The performance of the Dynavector P75MK4 will be nothing short of a revelation for almost all turntable owners. It is the best sounding unit I have ever heard on MM and the combination of this and a well chosen cartridge will rival or best most MC/Phonostage combinations for the same or lower total cost. For any Dynavector low output MC owner, this latest version running in phono enhancer mode will be near on impossible to beat at any price, given the cost of the P75MK4 is less than any of the MC models this makes it a veritable no-brainer.
What is Phono Enhancer (PE) mode on the Dynavector P75?
What is Phono Enhancer (PE) mode on the Dynavector P75?
PE mode switches the P75 from conventional voltage amplification to current amplification. Instead of presenting a fixed impedance load, the cartridge sees near-zero resistance, forcing it to output current rather than voltage. Dynavector designed it to improve magnetic field linearity inside MC cartridges, and the result is noticeably more dynamic, open sound. PE mode has three settings (4-10 ohm, 10-20 ohm, 20-50 ohm) matched to your cartridge coil resistance. It works with any MC cartridge, though results are particularly impressive with Dynavector models.
Does the Dynavector P75 work with moving magnet cartridges?
Does the Dynavector P75 work with moving magnet cartridges?
Yes. The P75 Mk4 supports both MM and MC cartridges. In MM mode it provides 40dB of gain with 47k ohm loading and adjustable capacitance (100, 200, or 300 pF) to match different cartridge requirements. The five gain settings (40dB to 63dB) and six impedance options (60 ohms to 47k ohms) cover virtually any cartridge on the market.
How does the P75 Mk4 compare to the Mk3?
How does the P75 Mk4 compare to the Mk3?
The Mk4 is a significant step forward. The most impactful change is the new ultra-low-noise switching power supply, which substantially lowers the noise floor and improves dynamic range. The casework is completely redesigned with an extruded aluminum chassis and glass front panel. Internally, a new high-current line driver improves signal integrity over longer cable runs. The gain, impedance, and PE mode options are expanded from previous versions. Critically, the performance gains come without a major price increase.
What gain and loading settings should I use for my cartridge?
What gain and loading settings should I use for my cartridge?
For MM cartridges, use 40dB gain and 47k ohm impedance. For high-output MC cartridges like the Dynavector DV-10X5 Mk2 (2.5mV output), use MM settings or 46dB with 100-220 ohms. For low-output MC cartridges like the DV-20X2 Low (0.3mV), use 60-63dB gain with 100 ohms in standard mode, or try PE mode matched to your cartridge coil resistance for the best results. The internal jumpers are accessible by removing the case side panels.
Can I use the P75 with non-Dynavector cartridges?
Can I use the P75 with non-Dynavector cartridges?
Absolutely. While Dynavector designed the P75 (and especially PE mode) with their own cartridges in mind, the wide range of gain and impedance settings makes it compatible with virtually any MM or MC cartridge. Reviewers have had excellent results pairing it with cartridges from Rega, Ortofon, and other manufacturers. The six impedance options and five gain settings cover the full spectrum of cartridge requirements.
