Best Power Amp for Adcom GFP 750 Pre?

I agree with Sean, however if you plan to use the pramp in the passive mode, the 750 with the Sunfire Signature amp is excellent.

Well I'm a firm believer in sticking with same manufacturers. . .so I say go with and Adcom amp. ..

I used the GFP 750 with a Pass Aleph 3 and it was a great match. Or if you need more power Aleph 2 monos. The GFP 750 IMO sounds a lot more transparent in passive mode. If your speakers are 89db @8ohms efficient you should be able to get plenty of volume with the 30watts per channel Aleph 3.

I have heard the 750 matched with a beefy Mac tube amp.The active mode sounded ok,the passive mode dry amd uninvolving.I would match the 750 with a C.J-55.The 750 needs all the liquidity it can get from an amp.Its just too dry.As far as the Aleph-3 as a match,maybe so but not in the passive mode.You would never get enough volumn and dynamics.The Alepth-3 needs more than unity gain.

I've used the gfp with Sonic Frontiers, AR and mccormack amps. I didn't think it mated well with the AR amplifier. There was quite a difference in sound quality using the preamp verses the CD direct. I recently put one together with the mccormack and find that the system actually sounds better with the preamp (in passive). The active mode isn't bad either, but does lose a little detail. I find that my tuner doesn't have enough oomph (how do you spell oomph?) to drive the passive mode well.
