I am looking for a good 2-channel power amp to drive my AKG K702 as well as a pair of Boston bookshelf speakers. I've tried Onkyo A-5VL from Amazon but unfortunately it was defective so I returned it and ordered another one and that was defective, too! So I am now wary of Onkyo's build quality. Too bad, I liked its slim profile.
If anyone knows a good power amp with optical input please let me know!
