Which Counterpoint Preamp SA-5000 or SA- 5.1???


I have a friend with both of the Counterpoint preamps and he says for me to pick the one I want and he will keep the other. So Counterpoint owners, which one should I pick and why?

Thanks and Happy Listening.

Just to add comment on this. I have always loved Counterpoint sound. I started with SA 3 some 20 years ago. Never, Never had reliability problems.

I have been using Mike upgrades for a while and they are nothing short of spectacular! I have upgraded SA 5000 and it beats pants off of CAT Sig II, Herron and BAT 5i that I also own. Better imaging, overall tonal balance, quiet etc. I listen to Classical and Jazz only. Rock listeners may not have same reaction. Mike is responsive and stands behind his work. It is actually a good thing for us audiophiles that Mike is away from the restrictions of manufacturing Counterpoint and is able to offer a truely unique and valuable service.
I have a 5.1. Go to the Counterpoint site, altavistaaudio.com, and read up on both preamps. The 5.1 appears to be generally regarded as better. They are relatively inexpensive, but in time you will likely have to ship it to Michael Elliott for repairs. My advice- when you experience your first breakdown, save up and get the unit upgraded. Reliability issues are not an issue with the upgrades.
My SA-5000A is a fabulous sounding preamp, never any problems. Mike is an honest guy and totally backs his work.
So far we own 5 SA5000s among our audiophile friends and all of them are trouble free and noise free. I do agree that it is a lot more complicated than SA 5.1. We prefer SA5000 over 5.1.
