Default Quicksilver Audio

>>Mono 120 Tube Amplifiers<<

Received a pair this week. Burning them in now. Nice presentation. KT120s now, KT150s next, NOS input/driver tubes coming soon. No QS mfg forum here on AA, posting here.

Interested in hearing from other QS owners.

Whatcha got?

I have a pair of original 8417 Quicksilver monos. Very open mid-range. Lovely little amps.

Nice. Those little 8417s are cool. Heard they sound good too.

QS Integrated amplifier. EL84 tubes. Very, very happy with this amp. No desire to look for the next best thing in this class/type of amp. Sounds natural, balanced and neutral within its power capabilities of 20wpc.

Stock input/driver tubes used in Mono 120s: new production JJ with EI Yugoslavia. They sounded okay, a little forward.

Ended up with NOS Mullard drivers and Tungsram or Mullard input tuber in front of the large Tung Sol KT150s for output tubes.

About 150hrs burn in time and it evolved to more of a 3 dimensional sound once broken in.

tima,
By chance are you keeping an extra stash of 8417 output tubes around?

If not, I see Mike@QS offers an alternative conversion service, and while not quite real triode, he converts them to EL34s for customers at a fairly reasonable price. Curios if anyone has done the conversion and how it turned out.

"System Dependent" of course, but worth noting after trial, error, and success:

INTERCONNECT changes sure make a notable difference (for better or worse) on the Mono 120s, and taking full advantage (top-to-bottom) of the KT150 output tubes after settling on preferred NOS input/driver tubes.

Sound stage, depth, texture, and detail comes through with more open-clear cables and midrange musicality can shine through too with slightly warmer ICs.

My "dealer" friend sells QS. He has the line stage pre, and it sounds even better than the JC2 pre-amp he uses most of the time for demo's (I use a JC2 in my system). I'd buy one, but I "need" a remote control and I prefer (not sure why) to use balanced (xlr) cables. If you've not listened to the QS linestage (non-remote version) - you really should because it's fantastic. And less than $1500!!!???
