Thanks, I'll look into the upgrade on the sub side. I could go with a PB2000, or if the price is right, a 3000.
On a nit-picky note FLAC is actually it's own codec. It stands for Free Lossless Audio Codec. It's similar to MP3 but it's completely lossless...so no information is sacrificed or compressed. That's why audiophiles like it. ***Edit, sorry, you DID say lossless already, my bad.***
But thanks for your help here. I've looked into the HSU's and yeah, hard to get in Canada without paying TOO much for them.
