The Adcom GFP-750 seems to get little respect on this forum, yet if you read every online magazine review the opposite is true, it's compared favourably to preamps costing 2-3 times its price. Used passively I have a gut feeling that it's an excellent preamp but its crucial that there isn't an impedence/sensitivity mismatch with the amp and the front end source. This is often the case with passive preamps and I suspect its coloring the impression that many have with the GFP-750. I've also found that with passive preamps it's important to use short lengths of cable and some cables work better than others. In my case I found Nordost Quattro Fil worked better than Cardas Golden Reference in a passive preamp I once owned, more dynamic and faster. In fact the cable change alone made my system go from sounding 'OK' to sounding excellent. Does anybody out there have anything to add regarding my comments above and is there anybody who's found the GFP-750 to be an excellent preamp even compared to much pricier preamps? I know at Audioreview.com there are many who swear by the GFP-750 and these same people have owned much more expensive preamps in the past. Thanks to all who responded.
