Hi, need some help with my new plan Right now I have my Htpc passing through video and audio to my 3D av receiver and this then being sent to my 5.1 speakers and tv by hdmi My current setup is Htpc gpu with 1. 4a hdmi Yamaha v371 which is bottom of the pile Boston acoustics soundware xs I know Ineed to uupgrade the amp, would prefer to stick to Yamahabut not eessential Problem is I will probably want to keep my 5.1 current set until I have a 5.1 set based around bx5 and whatever I get in future (I'm guessing it would be silly to run the bx5s as fronts in a 5.1 with the speakers I have as rears!) How do I proceed? Do I need 2 amps? Or would the receiver I'mgoing to get be able to run bbothsseparately? I really don't know how to proceed.
