When we fired these Quicksilver V4's up for the first time we were BLOWN away. They honestly just do everything right. And with their polished nickel chassis, they don't look half bad either :) These are equipped with a very special set of matched tubes: The Shuguang Black Treasure KT-88z. Hand-selected and tested, this particular matched set was from the first production run of KT-88z, as confirmed by the manufacturer, Grant Fidelity. All later batches used a different Chinese script, which they registered as an image trademark. Rare, and ohhh so nice.

- Liner Notes
- The V4 recreates a musical event on a scale and with a solidity, roundness, and three-dimensionality matched by few and surpassed by no other amplifiers, with sensational dynamic-range to boot.” Paul Seydor – The Absolute Sound, October 2002.“Connecting the Quicksilver Audio V4s quickly revealed that these were very good sounding amps indeed. Space, delicacy, transparency, and overall musical believably were of high order.” Bascom King – Audio, February 1998.Powerful, musical, and effortless–this is the sound of the V4. As with all Quicksilver’s amplifiers, the V4s are all tube and hand wired point-to-point. A bias meter is mounted in the chassis and individual controls allow each output tube to be biased separately. The amplifiers come with KT150s, but EL34s, 6550s, or KT88s can also be used.Matched quads will work best but are not necessary. The low screen voltage on the output tubes (300 volts) makes them last for thousands of hours of “on” time. The output stage has a separate power supply so that even maximum power levels will not diminish the sound quality. A new output transformer coupled with KT150s increases the V4 power to 170 watts into 4 or 8 ohms.
