Adcom pre amp versus Van Alstine

Buy them both! That's the spirit. Comparing them at home is the best answer.

It will be great to read your findings.                                                  

"@mrdmbman I have decided to buy them both! I will circle back with my review of both."

There you go, nice!  This is truly the only way to know, to help decide in your system, setup, and matching with your amplifier. There is always a buyer for the good used stuff, whatever you decide to resale later.  Be sure to use the exact same cables on both setups, if at all possible. Best of Luck.   

You will never look back ... AVA all the way.

Thus is probably not fair because I have not heard that model of VA. I am commenting because of some of the comments about Adcom. I have heard all of their pre's and consider most poor. However the GFP750 is a fine preamp, No other Adcom is in the same league. It is passive, it is active, it is single ended and it is balanced, doing all fairly well. I have met Frank and heard alot of his gear. For me, if I could get someone that I trust that clearly know them both and could tell me that the VA is better, I might go that way,  if not, the Adcom is a safe bet and I'd run with that. Plus, not likely that you would lose on resale of the Adcom.

I got the Adcom GFP 750 and tested it.

These are the other components:

Mcintosh Audio 2125 (power amp)
Cabasse artis baltic ii speakers and SVS SB2000 pro sub
Rega Planar 8 TT with Rega Ania Pro Moving Coil Cartridge
Bluesound Node 2, streaming from Qobuz
Teac ud-503b DAC
Audioquest cables

Previously I used the pre-amp option on Cambridge Audio CX81

The sound quality is incredible (at least compared to the Cambridge). Soundstage, precision and details have much improved. I am getting the Van Alstine next for the comparison!
