quicksilver v4 monoblocks

Many have owned them and most will tell you they are a great value, very reliable, and able to drive most speakers. What specifically do you want to know about them? What speakers do you want to use with them?

i have usher 6381's 87 db. @ 8 ohm. since i will be unable to audition them, basic sound, pors and cons compared to other brands in that price range.

They are powerful, great, great bass, and magical midrange, which is the trademark of QS amps. I have never heard anyone say anything bad about QS, look and search. I compared them with my CAT JL2 which are among the very best P/P tubes amps in the world, and while ultimate I prefered the QS, your talking about amps 3x the price and I could have lived happily with either. These amps are neutral with tube bloom, but not classic euphonic sounding - that works for me. You'll not find a more reliable, lifetime amp on the market and you will always be able to sell them for what you pay for them if you buy used - quickly to. I don't know what elese you are considering, but I've been a QS fan since my first 8417s years ago, and they remain Amercican made, reliable, with sound engineering and no flavor of the month nonsense.

also considering the atma-sphere m-60 mk3.

Another excellent choice. Are you speakers appropriate for OTL? I think you could love both.
