Released in 2007
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.
that if it doesn't sound WAY better than digital
playback it's pretty much a waste of time.
The ZP3 represents
our best effort to take your vinyl to the bodacious
lively and dynamic
3D experience it was always meant to be. We've
compared many high
dollar phono stages with the ZP3 during it's
development, some in the
5 figure price range. Many sounded like a really
good DAC. Sorry, but if we wanted vinyl to sound
like a really
good DAC we'd just sell you a really good DAC. A
phono stage is
make it or break link in your LP playback. It is
equally as important as the cartridge and tonearm if not more so.
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
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.

The ZP3 comes with hand selected low noise tubes. It is self-biasing so no adjustments are
the life of the unit. The signal tubes are 12AX7 and the buffer
is a 12AU7 all supported by the 5U4 rectifier and OA3 voltage regulator
tube. All included.
The ZP3 comes standard
with your choice of black figured wood base shown in the picture at the
top of this page
or you can have a contemporary style base in natural walnut shown
Custom bases can also be
made in the style shown below from any
hardwood including many exotics for an extra charge. Custom bases
are non-refundable. The wood bases for the ZP3 are user
interchangeable. That means you can purchase a custom base at any
time for your ZP3 and change it yourself !
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.
For low output fMC cartridges
1:20 ratio for use with 3~25 ohm
For high output MC cartridges
1:10 ratio for use with 3~100 ohm
For high impedance MC
1:12 ratio for use with 25~100 ohm
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!
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
* 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.
