This is just so typical of some posters here on the 'gon. The OP comes on looking for some reasonable advice about power amp or possibly preamp, and immediately he's told he make a big mistake and needs to get rid of his speakers. My recommendation is to sift carefully through the information you've been given so far. You can definitely go the beefy tube power amp route, but a lot of people find happiness with the tube preamp + SS power amp combo. There are some sweet tube preamps out there, particularly the ones with the 6SN7 tube. Check out some of the recent threads on the topic.
Tubes?
I have Revel Salon 2 speakers. Sensitivity is about 85 db. and 4 ohms. They are power hungry speakers. Currently, I am driving them with McIntosh 601's and a McIntosh solid state preamp. I was look looking at a pair of McIntosh MC2301. They are tube amps rated at 300 watts into 2 - 8 ohm loads. I listen to all types of music (sometimes at very high levels). I never run out of power with the 601's, but I am very intrigued with tubes. This may be a misconception, but I remember some friends who played guitar saying, tube watts were louder than solid state? Perhaps this is not really true or not true regarding home stereo. Perhaps the best idea is to keep the 601's and get a good tube preamp? Thanks, Dave
