Want to upgrade my Adcom GFP 565 preamplifier

I bought a used Linn Kairn preamp here on Audiogon, it is a very good sounding preamp in my opinion, a little hard to find but they show up here from time to time.

I would second the GFP750--very smooth and great soundstage. High quality components for the price. Can be used in active or passive mode--the passive is extremely neutral with a nice deep soundstage if you like that. Imaging is really tight, good sense of space. Bass extension is very good, and treble sounds airy. Just a very neutral sound in pure class A. Plenty of good reviews and discussion threads. Can run balanced and sounds best in that mode as it has true balanced design. Newer designs probably better this one, but for your setup it would be great (and for the price can't be beat.)

Thanks for you responses. I have looked at the 750 and am sure it is better than the 565. I do have concerns about a lot of negative reviews. In particular, the comments that it is clinical, life less and lacks smoothness in the upper end. This is probably a bit of snobbery but who knows. I am intrigued by the claim of increased soundstage and sweetness of tubed gear but tubes scare me. I don't want the expense of regular tube replacement or to worry that they need replaced.

I have not heard any Linn products, but have heard good things about many of their products. I will see if there are any reviews.

I was thinking of Classe CP-50 or 60 which have both received great reviews. However, being solid state, I am not sure they would be that much better than the Adcom 750.

Okay, I further reseached the GFA 750 including a review using my speakers and it is in serious contention if I can find one. The one on Audiogon appears to be sold.

I still would like to hear any comments on the Classe products or others in that league.

The 750 is far from clinical and lifeless. I think it is extremely musical and true to whatever source you feed it. The top end is extremely smooth, at least in the passive mode. Active mode, not so much--so maybe that is the criticism. I think many preamps are a bit too forward for my taste and that is why I like the passive mode. But you do lose some dynamics depending on your set up. I think the negative reviews are snobbery. But to each his/her own. Resale seems strong on these. I don't think you could go wrong if you tried it, didn't like it, and wanted to resell, but you'd want to pick one up for less than 750. Make sure you get the original, made in USA model with blue circuit board--it supposedly sounds better than the later made in Taiwan model with red board, and make sure you get orig box, manual, remote, etc........I have never tried a tube pre. Have thought about it but am not crazy about the heat, bias issues, maintenance, etc. Keep us posted!
