Miked, I have the Adcom 5802 Amp with a Carver C4000 Preamp and Canton Ergo 81 speakers. Let me tell you, the Adcom 5802 blows away the old Adcom Amps like the 555 Amp. The 5802 Amp sounds very sweet with a touch of warmness. But here's the catch. I had mine modified by Stan Warren. Stan Warren used to be the S in P.S Audio. This guy is an amazing modifier. He modified my 5802 for 300 dollars. He took out the so so parts and put in top quality parts. After this mod, i have to tell you, this Amp sounds so great. The Amp as it is, is a great Amp. But after the Stan Warren mod, this Amp goes to a new level. You can talk to Stan. He will tell you about the mods he does to the 5802 Amp. His number is 541 344 3696 Stan is an amazing modifier of Dacs, CD Players, Amps, Preamps. Ric_Wison@Yahoo.com
