Quicksilver Preamps?

They drive the tubes so they last about a year before microphonics and what not starts.

id like to add to the OP’s inquiry from Previous  owners and what they moved up to.

I started with Audible Illusions 2B ——> original Quicksilver Full Function preamp (better bass and dynamics) ——> Jadis JPL (bigger sound stage and more colorful) ——> Audible Illusions 3A (truer timber—I am apparently sensitive to this—not quite the bass or dynamics of the Quicksilver but really good; more realistic than the Jadis). Downside is too much gain. If I were in the market today, I would look at Supratek, Benchmark, and CODA.

Forgot to add—I went from Quicksilver 8417 amps to Silver 90s. Wish I had picked up a 190, 6C33C, and 120 monos—I obviously love Quicksilver amplifiers. They will drive anything within their power rating, seemingly immune to low impedance loudspeakers.

I had one on loan years ago, ans I thought that the sound was what some would consider classic tube in that the timbre and textures were good, and it was not at all harsh, but I thought that it was a bit lacking in drive and the big architecture of some other preamplifiers. Agree with pmm, not the best, but good value.

Some of the purist QS fans like the non-remote version claiming it sounds better.  Have friends with both and they like them.  Put really good caps in it and some nice tubes and decent interconnects and you'll enjoy it for many years. When you are done, someone will take it off your hands willingly.
