I have a pair of quicksilver amps, the silver sixty's, I use them to drive my 4425 monitors. And they sound fantastic. They are very dynamic amps. You have a great pair of amps. Amp and speakers should match. The 4425 monitors are 8 Ohm and their efficiency is 0.8%. They have great detail, they are neutral and very dynamic. You can play them at 65dB or 105dB and their composure does not change. With the 4425 20 watts is all you need. Also, your quicksilver amps have a gain of 25dB and need a preamp of at least 14dB of gain to drive the amps to their full sixty watt output. IMHO: I would try a preamp first, and if you do not like the sound look for different speakers. If you change your speakers make sure they are 8 Ohms or higher as that will make the quicksilvers very happy. I hope this helps.
