Quicksilver V4 Mono Amplifier (one pair)

Quicksilver V4 Mono Amplifier (one pair)

"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."1

"These amplifiers are the most neutral, revealing, and highest performing amplifiers in my experience. The V4s have exceptional resolution and are the most neutral tool for reviewing that I have ever used. The bass is deep, powerful, tight but resonant, and perfectly balanced with the upper bass and midrange. Sound staging is exceptional. You can spend a lot more for similar power, but in my experience, you probably will not get anything better in a tube amplifier than the wonderfully musical Quicksilver V4." 2

"A no-nonsense, timeless pair of amps."3

Product Info


Quicksilver builds equipment to last many decades of deep listening and musical enjoyment. Introduced in 1998 and with a new output transformer in 2014 to increase power, the V4 is an excellent example. Its sound excellence remains and continues. Powerful, musical, and effortless—this is the sound of the Quicksilver V4. As with all Quicksilver 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.
