Slam possible with Tubes instead of SS ??

Grannyring imagine what the A1's would sound like with MA2's or MA3's what a great sound that must be;maybe I will head down to Atlantic City and see if I can get some $$$'s out of Trumps pocket.Did you consider a larger tube amp like a VTL,Vac,Audiovalve or Manley's?

Rleff, yes I did consider those as well as the Wolcott P400's. I could not afford both the A1's and those big tube amps right now. I decided to try a used Sunfire Signature for $1500 and I was and continue to be amazed.

I doubt any SS amp could make these SL's sing any better to be frank. I see one for sale for $1750 now. Mine, like the one for sale, is the original one that is 19 inches wide and weights more than the 2nd version. I modified it to accept an IEC. I also sent it into Rita's Repair Service (authorized Sunfire repair shop) to have it checked out. It did need new power supply caps and some other things. It cost me $375 plus shipping to do this, but I am good to go for years now.

All of these Sunfire Signature amps should go to Rita's as they do have to be updated with newer parts based on comments from Rita's Repair. Consider this in the purchase price. They were made in 1998 or so and the power supply caps seem to have a fixed life. Rita's puts larger caps in so as to avoid any future issues. They also double check to rail voltages to be sure the amp is in spec assuring great imaging etc...

Trust me when I say this amp is magic on our SL speakers. Not at all typical SS sounding. It is very rich and full bodied with wonderful stage size and what seems to be limitless power delivery. Bass is scary good and the music is simply beautiful. My seller paid for 1/2 the repair bill so in the end the amp cost me about $1500.

Bob Carver made a great one here and for the money it is perfect on my A1's.

I just read the thread posted by Tvad about the noise problems associated with Plinius amps. Yes, they are a bit noisier than a lot of amps, but in my situation, the noise level is far enough below the threshold of hearing it at normal listening volume (and up), it's a non-issue for me. I do use a passive line stage, as suggested in the thread, this may help in lowering the noise floor.

The performance of this amp is so good, I don't mind a bit of extra noise, which I don't hear at all when playing music. The two trannies do hum, though, even when the amp is in mute mode. Though not perfect, the way they make music sound far outweighs their deficiencies, at least for me.

I am very tolerant of many different flavors of system sound, but I have very low tolerance for noise of any kind.

If I put my ear up to the speaker and hear anything other than silence when the system is on even if only at higher than normal volumes and nothing is playing, I consider it a potential problem, even if practically it is not apparent during normal listening.

I agree with Tvad that noise can and often does have a negative effect on overall sonic performance when present even if virtually impossible to hear flat out.
