I am considering getting some entry level Hifi headphones (possibly Sennheiser HD660s). Though this might not come right away, I am willing to complement it with headphone amp as well.
I already own an entry level 2ch system with an integrated amp (Sony STRDH190) and two sources : network streamer and turntable.
My question is this : what is the best way to use both sources and let me easily switch between the speakers and the headphones?
Using the front microphone output of the poweramp would work, but I haven't find any technical specs as to wether it would drive enough power for the headphones I'm looking into. I understand it might also be a bit stupid to buy such expensive headphones to listen through a possibly cheap component of the integrated amp.
Hence I am considering headphone amps as well. But from what I can tell, I would either need hook in between one of the sources and the integrated amp (and give up on listening to the other source through the headphone amp) OR get a pre-amp which will play the role of input selection (and possibly dish the integrated for a dedicated power amp).
Looking for some examples of how this situation is usually solved. Thanks!
