I have a GFP 75o, and old ARC SP-11 and a Melos Maestro Gold driving Melos Monoblocks or Bryston 7B Monoblocks with Dunlavy SC V speakers. My primary source is a Theta Data III to a Genesis Digital Lens optionally a Z-Systems rdp-1 digital preamp and a Theta Pro Gen Va upgraded to 24/96. I can drive my amps directly from the Gen Va using the Z- Systems. I use quattro fil on the audio and Orchids as the digital interconnect. I only use the GFP-750 in the Passive mode. It is quite somewhat drier compared to direct onto the monoblocks. It is fairly interconnect and amp sensitive. It does add hum compared to staight in. These are all minor changed compared to what the active preamps add. However many recordings subjectively sound better with the euphonious additions of the active preamps. In my experience with carefull listening to multiple combinations, Woodman above matches my experience.
Adcom GFP750 ??????
Heard fantastic raive about this preamp. Has anyone been listening to the newer unit and on what system and WHAT IT LIKE????? Have the 5802 and Canton Ergo102 speakers with the adcom GTP740 as the preamp. Sounds Great But I'm Sure I'm missing something by not going to a reference preamp!
