David Berning Co Quadrature Z with Stillpoint circuit board isolators and feet

Serial numbers 08391 and 08392 

These monaural amplifiers, are fully optioned with internal Stillpoint circuit board isolators as well as Stillpoint Ultra external "feet. They are the only pair  optioned with two sets of speaker binding posts. They were lightly used by one meticulous client (that owns many world class amplifiers and has multiple systems). They were traded in on a pair of the new David Berning 211 / 845 (switchable) Class A OTL mono amplifiers.

Buy with confidence.  The amplifiers are factory warrantied by Hi Fi One, for one year to the buyer. 

Only 4 tubes per channel are required for 220 watts per channel in the patented Berning OTL design, and they last 20,000 hours before replacement. Contrast these technology driven benefits as well as auto bias and plug n play use from 60 to 240 volt AC vs the competition and you have the reasons these OTL's are 21st century marvels. 

Technically and sonically.

This is an exceptional opportunity to purchase amplifiers that rarely come up for sale in the secondary market. Moreover, Berning amplifiers retain extremely high resale values. In some cases, considerably more that the last published original mfg. suggested retail price. e.g. the Siegfried and Micro Z which remain in very high demand many years after production ended.
