For sale is a pair of David Berning Quadrature Z amplifiers, Serial numbers 07423 and 07424.
They were purchased from Hi-Fi One and have been updated to the latest electrical and protection circuit specifications by David Berning. Additionally, a new chassis component is incorporated. The SMc Audio (Steve McCormack) "Gravity Base" that is a twenty-pound copper multi-layer damping and mechanical ground system expressly for these amplifiers. It forms the base of the amplifier, adding stiffness, rigidity, and a termination path for vibrational energy. Stillpoints OEM Ultra bases are installed, and the base will also accept any 1/4-20 pitch 'foot'.
The Quadrature Z incorporates the latest circuitry trickled down from the flagship 60 watts per channel class A 845 ZOTL. The amplifier will drive very difficult loads based on their patented ZOTL impedance matching circuitry. In this circuit design, 4 x 33JV6 tubes generate 220 watts per channel with 20,000-hourtube life. These amplifiers have built-in AC filtration, weigh 58pounds each, self-bias and run anywhere in the world without adjustment.
Price is $16000 for the pair. Reasonable offers will be considered. US lower 48 sales only. I do not have the original boxes, but I have had custom boxes made for the amps, so they are safe to ship. Shipping weight per box is approximately 75 lbs. Buyer to pay for shipping and insurance via FedEx from 94559.
Payment via wire transfer or certified funds only.
