Hey folks, first I want to say hello as I just joined so I could start asking questions, then I want to thank everyone in advance for any and all advice/assistance.
I have a HT setup right now, but I think I need a bump in the quality. I've got a Marantz receiver (I think it is the 5006), Polk Tsi400 fronts, Tsi100 and the similar size Polk Monitor series for surround and surround backs. I have a DefTech center and a polk PSW 505 Sub. I'm hooked into HiDef cable, I stream from my computer, and I have an entry level Samsung BluRay.
The receiver doesn't really drive the mains all that well, especially in surround mode with all channels driven. The Marantz does have one set of pre-outs for the L & R speakers, and I just got an Emotiva 2 channel 300watt amp, so I'm going to throw that in and see what happens.
The next things on my list are a sub, and probably an OPPO. The Polk sub is what it is, but at the time I only had the $125 to spend. I've been lurking and looking; the subs that have drawn my attention are the SVS PC12-Plus, and the Rythmic F-15. Do you good people have any other/better suggestions? Can I get better bang for fewer bucks?
My plan to this point has included eventually getting a Marantz 7701 pre amp (or an 8801 if I can break loose that kind of $$$) and of course another amp to run the rest of the channels.
Am I on the right track? Is it a better choice to replace the speakers than the receiver? If I did what speakers are a good choice? I've really just been looking at Subs, but I've seen a raft of speakers too.
I also have available an older Yamaha HTR 5790. That Yamaha has a full set of pre-outs, but it doesn't have the newest connections or decoding capability. Is there a "best course of action" form this point

?
Thanks Again,
Bob
