First of all hello and nice to meet you all! I have been lurking as a guest for some time and doing a bit of reading here and there to try and figure out what exactly I'm after, etc. Anyway, to keep things short(er), I currently have a hodge-podge 5.1 system comprised of: Denon AVR-1612 receiver Yamaha NS-AM200 mini-monitors as fronts http://usa.yamaha.com/products/audio-visual/speaker-systems/home-speaker-systems/ns-am200/?mode=model Yamaha NS-A638 bookshelves as rears http://usa.yamaha.com/products/audio-visual/speaker-systems/home-speaker-systems/ns-a638/?mode=model an ancient Yamaha NS-AC140 center (I can't find a specs page for it, it's from the early 90's I'm fairly sure!) and a cheapy "DCM" 10" powered down-firing sub. Oh and to top off the ghetto-style setup, I'm rocking a 42" Samsung LCD screen from ~2008Anyway, I have decided it's time to build a passable setup before i quit working to go back to school - and have thusly been researching to try and figure out what new parts I will really want/notice/can justify spending money on. So far, I picked out a very nice 75" Samsung 120Hz LED-LCD display: http://www.amazon.com/dp/B00ID2HI7U/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1XXMDIFC22AM7&coliid=I182VAHYFMM4AK&psc=1 Yamaha RX-A1030 7.2ch AVR: http://www.amazon.com/dp/B00D1VX2HS/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1XXMDIFC22AM7&coliid=I1SALR0ZKX6DFD Yamaha NS-C444 center: http://www.amazon.com/dp/B0000W4U2M/ref=wl_it_dp_o_pd_S_ttl?_encoding=UTF8&colid=1XXMDIFC22AM7&coliid=I31Z8UW6AUT9EZ Yamaha NS-6490 to replace the rears (and mount the current rears on the back wall): http://www.amazon.com/dp/B00018Q4GA/ref=wl_it_dp_o_pd_S_ttl?_encoding=UTF8&colid=1XXMDIFC22AM7&coliid=I3Q69MHCIQO17R and this BIC PL-200 sub to replace the laughable excuse that I have currently: http://www.amazon.com/dp/B001W3FXAQ/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1XXMDIFC22AM7&coliid=I3IC16ZJRCOLZC ------ For the questions: I know my current fronts are not exactly "home theater audiophile" equipment but they sound just fine (to me) now that i have them on stands at the correct height and aimed correctly so I am wondering if I should still consider replacing them with more modern 'home theater'-specific standing floor speakers? 2. Is my choice of center pretty good? I was trying to find something that went down to 60Hz, and above 20kHz and this seems to fit the bill - certainly much better than my early 90's junkbox. 3. Do you think it will be fine to swap my current rears to the far back, and use the new 6490's as the sides? My thought was it should be ok since I want the newer, better, higher-frequency-response boxes on the side as their sound will be more easy to audibly pick-up than something that's completely behind my head. 4. Is that AVR a good choice? I wanted a solid 7.2 AVR with a few features: more than 1 each of optical audio and digital coaxial audio inputs, several s-video inputs, and full analogue-to-digital video conversion + upscaling so I can hook up lots of old video game systems (NES, SNES, N64, SMS, Genesis, PS1, PS2) and only have to run 1 cable to the TV. I don't like Denon's menu system, or how the volume works (hold for more than a microsecond and it jumps up 100000dB), so I decided to give Yamaha a try since I like the sound of their speakers. 5. last but not least, what do you think about the subwoofer choice? My 'theater room' is about 12' x 24' x 8', carpeted floor and I have currently set the speakers and furniture up such that the 'sweet spot' is ~ 11' from the TV wall. Last weekend I cobbled together some stands to get the speakers all at appropriate heights relative to my seat, and that already made a HUGE world of difference improving perceptible sound field, clarity, directional perception etc but I want to really bring this room up a few notches before I don't have the luxury of a full-time income. I don't really have a 'strict' budget per se, but this is already amounting to ~$4500 for the new pieces I already expect to purchase, so I would like to keep total cost in the same ballpark if there are different things I should be doing. -- Thank you so very much for reading my novel of a questionnaire and I appreciate any and all advice or suggestions!
