The Quadrature Z is a twin pair of monoblock amplifiers that
retail for $33,000. You can get a brand
new one right here on this site directly from the company's exclusive sales
agent, a great guy to work with. My Quad Z may
as well be brand new. It's lightly used
and in pristine, nearly mint condition inside and out as were the other items
I've sold here recently. I'm sure my happy
purchasers would attest for you personally. I did not find a single scratch or blemish
while taking pictures in bright light and therefore the rating of nine. Regrettably selling for personal reasons.
You'll find all reviews range from positive to glowing or
better. The advent of the OTL was a
monumental achievement but damping and impedance mismatches were by-products. David Berning pioneered and patented
solutions to the issues of load tolerance and heat dissipation. It's the ONLY solution in its class, the only option this side
of $75,000.
The Quad Z utilizes radio frequency re-mapping to circumvent
the stresses of heat generating power consumption. Since the audio signal rides a carrier instead
of a transformer there is nothing to distort the signal. This allows for a better than 25:1 turns
ratio. So the output tubes can work with
lower current and higher voltage. The lower
current greatly prolongs tube life while the voltage capacity remains largely
unaffected. Re-mapping using radio
frequency instead of an output transformer is the genius of David Berning.
So only 220 watts per channel with four
tubes per channel. You may experience more than 20,000
hours of tube life! That could outlast your mortgage!!! My original 33JV6 tubes probably have fewer
than 1,000 hours of usage. And you can
easily find them online for less than ten bucks a piece.
You get both Quadrature Z amplifiers in their
original boxes along with the manual.
