Quicksilver amp owners

I owned the 90 watt Silver Monos for a few years. The good points, (compared to the solid state Mac amp that I was also using in the same system during the same period)were the crystal clear midrange, and the 3-d dimension of voices. The bad part was the plummy bass, and the obviously uneven frequency response. (I was using Spendor SP100 speakers)

Roxy's description is right on. I had a pr. of the KT88 monos and they had pretty much the same sound.

I also had the KT88 monos. I agree with the above, however, with Quad esl 63's
they were an excellent match. Still, subs were desirable (and difficult).

To get the Quickies to stand up and bark, I put in some good caps, polystyrene to be exact, upgraded the power cord over the cheap lamp cord which was rotting away, and they do a great job on bass now. The misperception is that the bass is loose. They need Winged C tubes or JJ tubes to have tight bass, and the mods. I used mil spec caps, but the RT by REL (michael percy) should do the trick. They are .22/600volt types. The most important factor in bass is the matched damping factor from speaker to amp. The bass is very firm and tight on my Maggie 3.6 now. Jallen

Also own KT88 Mono's -remember all the 88's are at least 13-14 years old .Mine were remarkably good sounding even with pretty sad valves in 'em. Once re-tubed (MP's of JJ Kt-88's ),NOS 12FQ7's and Chinese 5AR4's - they are simply wonderful. Bass performance does not have the control or slam of a high current SS amp - but it sure is a lot better ( more extension - better detail/control)than any of the Dynaco St-70's , the Marantz 8B or the Citation II I owned years ago.And the Quickies voice range will leave you smilin , HF performance is very accurate and at the same time very non-fatiguing. I use a couple of pairs of Paradigm Studio 20's and yeah -matching amps to speakers is always a issue.
