I've got a Denon 3802 in the bedroom system, and really, I'm very satisfied with it's performance as is. However, I've also got a 12 year old Adcom GTP400 tuner/preamp and an Adcom GFA 535 power amp (very conservatively rated at 60 watts per channel, although I've heard or read somewhere that it's really more like 80) combo that I'm not currently using at this time. I also picked up an old Adcom GFP 565 preamp that seems to work OK dirt cheap at a yard sale of all places. Should I integrate some combination of the Adcom equipment into the system with 3802 for 2 channel, and if so, how would I hook it up? I think I could do it through the tape monitor loops on either of the Adcom preamps into the Denon preout/ins, or is there a better way? I think I read a review somewhere before where they measured the 3802's 2 channel stereo output at like 127 watts per channel, or something like that. Would I be better off not using the little Adcom power amp instead. I mean, I could see it for sure if it were one of the little baby Adcoms bigger siblings of say at least 100 watts per channel, but in this particular case, would the 3802's amps actually be stronger? For one thing, I'm pretty sure that the tuner in the Adcom would be better than the Denon's, and I know the preamp section of either Adcom model I have would be better for 2 channel stereo. Also, I'm pretty sure that the Adcom GFP565 is a better preamp than the GTP 400, but it has no tuner (but that wouldn't be a problem as The Denon 3802 would still have one on it). Plus the 565 has 3 sets of main out jacks and a switch to engage a processor on the front panel, whereas the 400 has none of that. The 400 only has 1 set of main outs, and no processor switch. Would any of this be a worthwhile upgrade, especially since it wouldn't cost any additional money other than maybe cables? BTW, the speakers are Polk RT1000i for the main left/right channels. The cd player is an old (about '97 vintage) Yamaha changer. I think 735 or something like that is the model #. At that time, it was either their top of the line or 2nd from the top of the line cd changer. I figured I could run the CD players outputs straight into one of the Adcom preamps. Also, would the Denon 3802's DACs be better than the Yamaha cd players internal built in DACS? Would I maybe actually be better off hooking it up to one of the 3802's digital inputs? Opinions, advice and suggestions please, and thanks in advance.
