Like I said, I need to keep the player from that set for 3D playback and stuff, so there seems little point to getting rid of just the speakers. And as I also said, I’m perfectly happy with the sound quality I get from the current setup when playing BD directly through the HT system. It actually packs almost too much punch for my tiny living room and thin walls.
Plus the entire HT setup ran me about $200, so I don’t imagine I could get a very good price for it if I wanted to sell it.
If it only ran $200 originally - that is scary! You really need to upgrade that thing. It’s disturbing to know your listening to the classics on that. 😉
However, if you are dead set up keeping the player (and not just upgrading that too to a dedicated player only), then you will only want to upgrade the subwoofer as others have said. I did that once before too. Mine was a speaker system from Cambridge SoundWorks that came with a passive sub woofer. Once I upgraded the AVR to one with a dedicated sub out - there was no looking back. Nothing like a good thump!
I do think the recommendation for the new Denon AVRs is a good one. But don’t overlook the buying a refurbed AVR from the main companies to save $. Denon’s own site has a link and I bought my first real AVR via the Harman Audio store on Ebay.
I love the warmth in the sound from the Harman Kardon AVRs but for some reason they always have technical issues with connectivity (at least they did years back when I was active on the AVSforums). Denon has been very good to me though.
