Hi,
If you can find an Onkyo 805, that will do the trick very nicely.
I am also a musician and use my receiver plus a cd recorder to record my own
guitars; acoustic, classical and electric.
Yamaha is also nice, but I will go a little higher in the line up. I like a record
selector as a nice feature, but it is not necessary. Digital inputs and outputs are also good in your case.
If you can stretch your budget a bit, look at Onkyo & Yamaha mid/high ends.
But my vote goes to Onkyo with THX Select2 or Ultra2, plus Audyssey
MultEQ XT and excellent sound quality & value. The Onkyo 706 is also worth
considering as well as the 705. But the 805 is top notch.
If you really like Yamaha, look at the 1900 or 3900. But you will have to stretch a bit more. And in my opinion, it's worth it.
Hope this helps,
