A friend of mine is looking for an entry level receiver, and is looking at the onkyo sr501. He plans to use a headphone amp as well, so I figured using pre-outs would be the best way to get a clean signal into that amp, but the sr501 doesn't have L,R preouts. Would the VCR or TAPE stereo outputs work the same way as standard pre-outs? Is it all just line level output? he would need those outputs to be working regardless of the input signal as well. thanks for any help.
