Classe Model 4 and Model 25

Currently using an SP3a1 and a variety of vintage power amps, both tube and solid state.  Depends on the speakers in play.  I would assume the 25 is a better power amp than what I've got, but I had an HK Sig 1.5 from the Madrigal factory circa 2000 that was not competitive with what I kept.  Running Maggies, Thiels, and Altec 604, depending upon the mood, music, and the day.  Also have some vintage electrostats in rebuild that will like lots of power when done.

Great info - thanks!  I know this is mid 90s gear, so it may need a little bench time.  Main concern is resale if it doesn't sound better than what I've already got in place.

The phono stage was better than the Threshold FET 2 that owned before the Classe. BTW, the power amp that I used with the model 4 was a Classe model 15. Make sure that the model 4 includes a phono stage. There was a line only version . I sold the Classe gear about 15 years ago!

@Paradisecom, @yogiboy,
Thanks for your comments. Yogiboy, could you elaborate on the phono stage a bit, perhaps how it compared with other preamps?

@ pickindoug
I’ve owned the model 4. I had it paired with a Classe power amp and the combination was very nice! I doubt that you would go wrong with it!!

I can't comment on the preamp, however I do have a Model Ten amplifier and it is very nice.  It makes any speaker I run off of it just sing. That amplifier family is one heck of a performance bargain now, IMO.
