LPs + ZEN = Magical combo.
Youāve spent years building your dream LP collection. We know because we have done the same! TheĀ ZEN PhonoĀ is a wonderful enhancement to your vinyl setup. It will max out every MM/MC cartridge. Choc full of AMR/iFi trickle-down vinyl technology, it will have you poring over your LPs into the wee, small hours.
Specād to make you smile
Unlike any other entry-level phono stage. TheĀ ZEN PhonoĀ has:
- MM/MC fromĀ 36dB >72dB gain. Super-silent noise floor -151dBV
- Precise RIAA with Balanced output, performance comparable to +$1k phono stagesĀ
- AI sub-sonic filter. Addresses warpĀ withoutĀ eliminating bass or causing phase issues
Hissless whisper
Flagship phono amplifiers create their own power supply off the mains, like a mains regenerator. This is fundamental to a well-designed phono stage. Without this, it will struggle to amplify the signalĀ withoutĀ added noise. This is why phono stages āhissā so annoyingly.
Unusually, theĀ ZEN PhonoĀ has its own high-tech clean power supply. It creates a 1.2MHz power supply (20,000x mains frequency of 60Hz). In this circuit, a 10uF filtering capacitor = 200,000uF at lower, audible frequencies. With serious levels of noise filtration, it performs at the level of well-designed LC filtering circuits as found in classic tube amplifiers. Further, located on its own āislandā PCB, it is isolated so there is no noise pollution of the analogue stage. Just super clean +/- 12V DC.
Measured EIN (Equivalent Input Noise) is -151dBV. It is 20dBV quieter than some Stereophile Class A+ phonos which are -131dBV.
Mil-spec RIAA
The EQ circuit uses multiple TDK C0G capacitors in parallel. This is for best stability and the least distortion. They beat polystyrene capacitors and are close to Teflon. Already using the lowest tolerance capacitors combined with multiples in parallel, tolerance is exponentially improved by the square root of the number of capacitors. This is quite a natty circuit design.
The RIAA EQ tolerance level (+/- 0.15dB) is impressive as it is en par with hand-selected capacitors!
With great circuit comes great components
TheĀ ZEN PhonoĀ has some seriously good audio components backing up the fab circuit design which has trickled-down from its ultra-fidelity AMR PH-77 and iFi iPhono siblings. Scroll down for more on the most consequential circuit highlights/boutique components.
Super sub-sonic
The intelligent sub-sonic filter is from the iPhono range and is quite special. Normal sub-sonic filters remove ārumbleā AND bass and cause phase issues. Our unique AI phono sub-sonic filterĀ removes ārumbleā only.
