Id suggest looking into HarmanKardon and Rotel
Both of those companies have teriffic power supplies in their receivers so no worries there and they both sounds great - Yamaha is good for HT but ive heard (and I really have heard) they sound like ass for music; which is a pity. But they are great for HT
If you end up with a receiver that is considered 'high current' you will get a much better sound - I recently learned that the more wattage you have, not only is it safer, but it sounds much better
I hope I dont sound condescending or anything - Im not a real audio pro I just dabble a bit
