    Any 200 WPC or larger amp will do, but it will take a larger sub to fill that size room with balanced sound.

    Yep. Put the amp on hold and get yourself a badass sub instead. The Rti12's are OK, but they're not a substitute for a dedicated sub. A bigass sub will make a much greater improvement in your HT system than an amp.
    HT/2-channel Rig: Sony 50” LCD TV; Toshiba HD-A2 DVD player; Emotiva LMC-1 pre/pro; Rogue Audio M-120 monoblocks (modded); Placette RVC; Emotiva LPA-1 amp; Bada HD-22 tube CDP (modded); VMPS Tower II SE (fronts); DIY Clearwave Dynamic 4CC (center); Wharfedale Opus Tri-Surrounds (rear); and VMPS 215 sub

    it seems my denon at 80 watts per channel, doesnt provide adequate power
    as i can turn the volume all the way up ---max and it doesnt blow me out of the house- dont get me wrong it is loud and probably not played at this level normally, however in SACD and DVD-A mode it is often played at -6 to 0 on the volume setting, which makes me think there is little to no headroom left.

    so i assume at louder levels when one has to use the volume level at more than half way all the time it needs more power, is this a correct assumption?

    power is an issue, and a low levels the speakers just dont shine at all.


    but the sub is not as tight as i would like, but i can shake remove the porcelean figurines my girlfriend has on the shelves in the entertainment center

    anyway
    what sub would you recommend, i have read good things about the SVS subs, but thought i probably needed power first?

    FWIW there are a few Marantz MM-9000 on Audiogon for ~600.00. This is a 5 channel 150W amplifier. That price would leave room for a sub too if you wanted. I have not heard them or seen a professional review but if I had the money would like to try one.
    AVR: Elite VSX-21TXH
    Amplifier: B&K 7250 Series ii
    Misc: Velodyne SMS-1
    Mains: RTi-10
    Center: CSi-5
    Rear: Boston DSi460
    Sub: SVS PC-Ultra
    TV: Panasonic TC-P58V10
    DVD: Panasonic DMP-BD60K

    Welcome MWB.

    I would definately get the amplifier first. Look into getting an Outlaw, Parasound, Rotel, Sunfire, Earthquake, etc. You can get 3 channels or just get a 5 channel & be done with it.

    I wouldn't look at anything less than 200wpc. If you don't mind used, take a look at Audiogon.

    And talk to the people at SVS, they will help you get the right sub for your size room.
    Marantz AV-7705 PrePro, Classé 5 channel 200wpc Amp, Oppo 103 BluRay, Rotel RCD-1072 CDP, Sony XBR-49X800E TV, Polk S60 Main Speakers, Polk ES30 Center Channel, Polk S15 Surround Speakers SVS SB12-NSD x2

    I concur. If you have a $1500 budget, you can get a very good 5 channel amp for $700-900 and spend the rest to get the biggest SVS you can afford.

    Also, if you sell the PSW505, you may have a couple hundred more to put towards the amp/SVS purchases.
    Stereo Rig: Hales Revelation 3, Musical Fidelity CD-Pre 24, Forte Model 3 amp, Lexicon RT-10 SACD, MMF-5 w/speedbox, Forte Model 2 Phono Pre, Cardas Crosslink, APC H15, URC MX-950, Lovan Stand
    Bedroom: Samsung HPR-4252, Toshiba HD-A2, HK 3480, Signal Cable, AQ speaker cable, Totem Dreamcatchers, SVS PB10-NSD, URC MX-850
