The Dynavector P75 Mk4.1 is a compact, full-featured MM/MC phono preamplifier with gain from 40dB to 67dB, MC loading from 30 to 470 ohms, three capacitance settings, and Dynavector's patented Phono Enhancer (PE) mode. New in the Mk4.1, it runs from a USB-C Power Delivery adapter, and its internal power supply operates at 1 MHz, far above anything you can hear, so hum never gets a foothold. At 160mm wide and 500 grams, it fits anywhere but performs well beyond its size.

The P75 Mk4.1 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 Mk4.1

Seven Gain Settings: 40, 42, and 46dB for MM and high-output MC, 52dB for medium-output MC, and 62, 64, and 67dB for low-output MC, all set with internal jumpers.
Wide Loading Range: 30, 60, 82, 100, 150, 220, and 470 ohms for MC, plus 47,000 ohms for MM, with board positions for custom resistor or capacitor values.
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.
Four PE Coil Ranges: PE mode is set by cartridge coil resistance, with settings for 4-5, 5-10, 10-20, and 20-50 ohms.
USB-C PD Power Supply: New in the Mk4.1, the isolated internal supply runs from a USB-C Power Delivery adapter and operates at 1 MHz, well above the audio band. It draws about 2 watts in use.
Three Capacitance Settings: 180pF, 280pF, and 380pF input capacitance for fine-tuning MM cartridge response.
Subsonic Filter: Also new in the Mk4.1, a steep rolloff subsonic filter removes turntable rumble and the effects of warped records.
No Mains-Frequency Parts: The power supply contains no mains-frequency or other low-frequency components, so the hum problems common to conventional phono stages are designed out.

Phono Enhancer (PE) Mode

The P75 Mk4.1'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 set by your cartridge's DC coil resistance, with four ranges (4-5, 5-10, 10-20, and 20-50 ohms). Dynavector lists 5-10 ohms as the most common setting.

What's New in the Mk4.1

The headline change is power. The Mk4 ran from a 12V DC wall adapter; the Mk4.1 replaces it with a USB-C Power Delivery input. The P75 negotiates the power it needs from a USB-C PD 3.0 (or higher) adapter (25W minimum, 30W recommended, with a 15V at 2A profile), and the adapter is supplied by your dealer. Inside, the isolated supply switches at 1 MHz, so its noise sits far outside the audio band, and there are no mains-frequency parts to hum in the first place.

Dynavector also added a steep rolloff subsonic filter to tame rumble and warped records, and revised the gain and capacitance options. Low-output MC gain moves to 62, 64, and 67dB, and MM capacitance moves to 180, 280, and 380pF. The P75 ships set for low-output MC at 64dB and 100 ohms, which Dynavector says suits over 95% of low-output moving coils.

Versatile Loading and Gain Configuration

The P75 Mk4.1 accommodates virtually any phono cartridge through its comprehensive loading options. MM cartridges run at the standard 47k ohm impedance with selectable capacitance (180, 280, or 380pF) to fine-tune high-frequency response. Remember to add your tonearm and interconnect capacitance, which can be surprisingly high. MC cartridges can be loaded from 30 to 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 67dB (for the lowest-output MC designs like Dynavector's 0.26mV Te Kaitora Rua). All settings are made with internal jumpers, no soldering needed. Always power down before changing them.

It’s clear, but not clinical. Detailed, but nowhere near excruciatingly so. So quick, agile and able to move the music along with superb alacrity that it’s nearly addictive. Any slight glare or vague artificiality that occasionally pegged the old P75 as a reasonably affordable design is gone, baby, gone. Everything here is high resolution and cohesive, musical, taut, tonally colorful, texturally rich and largely neutral. This is darn good hifi.

Ed Kobesky,Positive Feedback · August 2026

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.

Jason Kennedy,The Ear

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

Dennis Russo,Critical Blast

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?

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 four settings (4-5, 5-10, 10-20, and 20-50 ohms) matched to your cartridge's DC coil resistance. It works with any low-output MC cartridge, though results are particularly impressive with Dynavector models.

Does the Dynavector P75 work with moving magnet cartridges?

Yes. The P75 Mk4.1 supports both MM and MC cartridges. In MM mode it runs at 47k ohms with 40, 42, or 46dB of gain and selectable capacitance (180, 280, or 380pF). Add your tonearm and cable capacitance when choosing a setting. With seven gain settings from 40dB to 67dB and MC loading from 30 to 470 ohms, it covers virtually any cartridge on the market.

How does the P75 Mk4.1 differ from the Mk4?

The biggest change is power. The Mk4 used a 12V DC wall adapter, while the Mk4.1 runs from a USB-C Power Delivery adapter (USB-C PD 3.0, 25W minimum, 15V at 2A) and its internal supply operates at 1 MHz, well above the audio band. The Mk4.1 also adds a steep rolloff subsonic filter for rumble and warped records, and revises the settings: low-output MC gain is now 62, 64, or 67dB (was 60 and 63dB), medium-output gain is 52dB (was 56dB), and MM capacitance is 180, 280, or 380pF (was 100, 200, or 300pF).

What gain and loading settings should I use for my cartridge?

For MM cartridges, use 47k ohms and the standard MM gain of 40dB, adding 2dB or 6dB if you need more level. For high-output MC cartridges like the Dynavector DV-10X5 Mk2 (2.5mV output), use the MM settings. For 1mV medium-output cartridges, use 52dB at 470 ohms. For low-output MC cartridges like the DV-20X2 Low (0.3mV), the factory setting of 64dB at 100 ohms suits most, or try PE mode matched to your cartridge's coil resistance. Always power the P75 down before moving jumpers.

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. Seven gain settings and MC loading from 30 to 470 ohms, plus positions for custom resistor and capacitor values, cover the full spectrum of cartridge requirements.
