I own this amp. It does sound awesome. I pair the GFA-6002 with an Adcom GFP-565 and I am very happy. For those without a GFP-565, I have paired the GFA-6002 with a Little Bear P5 (with audio grade tubes installed) and it sounds fantastic. I also have an older generation Adcom GFA-545; the GFA-6002 sounds better.
