Ive decided to upgrade to one of these from my 555II and would like to know what the difference between the two is as the 715 sells for a little over a 100.00 more.I want the 715 but cant find any on ebay or audiogon right now but Im sure one will pop up soon...I hope.

maybe its GFP not GFA ?

Yeah,, Sorry about that. GFP-710 vs GFP-715
Is right...that's a pre-amp not a power amp so the prefix is GFP. Read Tools' thread if you want to see raves about the GFP-715.
The GFP-750 is, supposedly, even 'better'.

Seen it.Its one of the reasons I want one.Im just curious as to the difference between the 710 and the 715 is all...
Check out heiney9s post on Adcom pre-amps....this is a brief review by someone who knows these units very well!
The best pre amp Adcom made was the GFP-750. It was a Nelson Pass design based very closely on his $4000 Aleph P, which is considered among the best sounding SS pre-amps. The 750 is a dead neutral preamp in both passive and active mode. If you don't like dead neutral sounding components I'd steer clear of it.
I have one I'm borrowing from my brother...........it's dead neutral and when paired with my warm, open Aleph 30 amp it certainly sounds much different then what I'm used too. For me the jury is still out as to whether or not it has the correct synergy I'm looking for. That said, it's a fantastic sounding pre-amp.
The GFP-750 retailed for between $1250-1500 depending on when it was purchased. Typically mint units sell in the $800-950 range used with lesser units (many missing the remote) selling for $650-800. I believe you can still get the remote from Adcom, but if you find a unit w/o it I'd call Adcom to make sure.
The GFP-710 and GFP-715 are also among their better designs. Anything with a tuner in it is not the greatest and leaves a lot to be desired. The GFP-555 is also one people commonly see.......not the greatest unit either.
This would be my only recommendation for Adcom pre-amps
GFP-710.......in that order. Anything else short of free; I'd look else where.
Hope this helps

P.s. we were using the GFP-750 to run Ted's currently acquired (by my brother) BAT VK-120's since the Adcom is a true balanced pre and they sounded absolutely fantastic, dynamic, balanced, very open and detailed, not a hint of harshness. If it's good enough for those; it's good enough for anything

I really wanted the 750, but i am very happy with the 715 right now.
If I ever come across one I might have to get it and do an A/B test between the two.

All I want to know is what the 715 has that the 710 doesnt have.IE: Better quality parts,remote,phono stage,etc,etc...
