Phono preamp question

I have to chime in with agreement, the GFP-565 phono pre-amp is quite good.  Better in fact than anything I tried in the $500 range from the likes of Graham Slee, Creek, and the like.  Among other things it has an extremely accurate RIAA equalization curve.  Mine was bought new in 1986 and still meets spec. too, which is rather remarkable.  It really sings with a good MM cartridge like a Shure V15, Stanton 681 or 881, Ortofon 2M Bronze or Black, or Goldring 1042.

Which  Graham Slee did you try.?  I haven't used the Adcom but am impressed with the Graham Slee I have been using.  The Graham  Slee Gram Amp 2 SE, with a high output MC Dynevector 20X.

Thank you folks for all the input. One of the reasons I really stretched my budget to get the 565 back then was all the great reviews for its phone stage since I only listened to LPs at the time. Last week a buddy of mine brought over his Vincent PHO-701 preamp he had just bought and the thing looks real beautiful with the tube lit up, etc. I must confess the overall sound was a little warmer. Not sure how to explain but the pops and general LP surface noise was less noticeable/annoying. I initially thought it had less detail but after a few records it seemed all the detail was there but just more fluid. I’m thinking the age is taking some toll on the 565 and some electronic TLC could revive the unit. I just ordered a tube preamp that has a phono stage for my other system and expect it any day so I can try it with the turntable and see how it goes. Might consider a separate tube phono stage since they seem to have a different sound texture.
