I've been using a pair of A2s for a while, until recently I've upgraded to a pair of bookshelves, a sub, and a stereo receiver. It definitely sounded better, but the receiver is slightly faulty and won't drive the bookshelves if I plug a pair of headphones in and unplug them later on. (yeah that stuff was sort of unrelated but if anybody has any suggestions it'd be great; the receiver is a Yamaha RX-E200, old stuff.)
Anyway, I've stumbled across a deal for a NAD 7125 receiver and a pair of Polk T15s for under $150 CAD. Looking around, it seems like this would be a decent deal, correct?
However, how would I go about connecting my sub to the new system?
Thanks!
