Released in 2007 -  this phono stage replaced our well respected ZP2.0.  It features a passive RIAA with tube rectification and tube voltage regulation.  It uses 12AX7 tubes for the RIAA stages and a 12AU7 for the output buffer stage. It has 42dB of gain with a 47K input impedance.  It is a maintenance free design, easy on tubes, noise and hum free and perhaps most importantly it sounds unbelievably good.  If you know anything about the ZP2.0, you would know it was 6 years in the making with the most R&D we've ever invested in a single product.  The ZP3 is better. 

Our feeling regarding Vinyl playback is simply that the sound should destroy digital playback - so to that effect this is a flagship product.  No cheaper models, no further improvements either.  It represents our best effort to take your vinyl to the bodacious lively and dynamic 3D experience it was always meant to be.  We compared many high dollar phono stages with the ZP3 during it's development, some in the 5 figure price range.  Most of them sounded like a really really good DAC.  Sorry, but if we wanted it to sound like a really great DAC we'd just sell you a really great DAC.  A phono stage is the make it or break link in your LP playback.  It is by far more responsible for the enjoyment of the playback than the cartridge.

FOR MOVING COIL CARTRIDGES

We believe the best way to step up a MC cartridge is with a wide bandwidth transformer, and we offer your choice of 3 different types.  This is done in a separate black metal chassis.  You can purchase this separately by selecting the one that best matches your cartridge, or call us and we'll recommend the best match.

All three models feature adjustable cartridge loading via the gold knob on the front of the unit so that you can dial your cartridge in as you listen to it!

The ZMC's feature Sowter of England step up transformers made from Mumetal (76%Nickel) laminated core for minimal harmonic distortion and exceptional bandwidth. 4 separate electrostatic screens for rejection of hum and noise in the cable connecting between the cartridge and transformer. Multiple interleaved windings ensuring exceptionally good bandwidth. The high bandwidth and very low phase shift ensures excellent transient response. Mumetal can for magnetic shielding is standard.

Typical response is 10Hz ~ 100kHz.

* YOU WILL HAVE THE OPTION to add a ZMC1, ZMC2 or ZMC3 when you
   purchase the ZP3 phone stage.  Since it uses European Transformers,
   you'll have to check the shopping cart for the current price.

ZP3 FEATURES

Single Ended Triode Class A1 operation with a tube rectified high current power supply that is five times bigger than required.  The liquidity of this design proves the best form of artifact free regulation is brute raw current - you can hear it. Add to that the tube regulated B+ and the ZP3 gives new definition to the phrase "grain free sound".

There is a standby switch allowing you to keep the unit warmed up all the time if you like.

ZERO maintenance, no adjustments, no biasing, long tube life are just some of what make this such a hassle free pleasure to own and listen to.

The wood chassis is completely foil lined for 100% shielding giving you hum free, noise free operation at all times.
