I see your point about the BD and I use a PS3 for my BD viewing. I like the Oppo because it offers true SACD output at a price that fits my budget.
Hehe, duh, I totally missed that, lol. You know, Klipsch is one of the better reputed sub values for entry-mid Big Box Brand subs, AFAIK.
The usual candidates are the ID brands (although I have a BM brand). SVS, HSU, Outlaw, Epik, Elemental Design. Smaller budget may include others like Dayton, x-sub from AV123, others. I won't be the only one, but I heartily recommend in thinking
overkill for the sub. It will
completely change your HT experience.
Some are ugly (eD), some have long back-orders, some have pricier shipping than others, but they almost all have month long trial periods. If looks have no bearing at all, eD seems to be the best value. I'd be curious about the Epik entry sealed sub, but then there are those who believe ported subs that are tuned low enough work better for HT. (Mine is sealed).
I think most here would agree that the brands I've listed will
generally get you more for the money, or just more period, than Yamaha or Klipsch.
Cheers.
