What's the verdict on the Adcom GFA-5802


I am considering changing(up grading)to Adcom GFA-5802 amp and GFP-750 pre. I currently am using a Parasound HCA-1500a and Parasound P/HP-850 pre, will I be disappointed? Is there a better high power, high quality, budget combo out there? I have Audio Physic Virgo II speakers.
Thanks for your help.

Thanks for your advice. A used Adcom GFP-750 showed up on the GoN like a omen for $525...so I snagged it! I'm going to see how it sounds with my Parasound, then re-think my Amp selection.
My vote would be the Ayre V-3......
