    I have been upgrading my system a little. I went from an H/K AVR25...75wpc x 2, 65x5 I think, with an old 50W Velodyne. Now I have an Integra DTR-7 for my pre-pro, a 500W Infinity sub, and two Audiosource Amp Ones...one for each front channel giving me around 200wpc x 2. I had two sets of floorstanders...Klipsch KG5.2's (sensitivity 96d, 100W RMS rated) and a pair of Polk Audio LS50's (sensitivity 89db, 250W RMS rated) both 8ohm. I always thought the Polk's sucked so I stuck them as my rears and used the Klipsch up front, but I guess I never threw enough power at the Polks because ...DAMN!....hooked up to those 200wpc external amps they kick butt! YOW...frickin'...SAH!...is all I can say.
    Since I have a matching Polk Audio center channel I sure would like to get another pair of the LS50's for the rear now. Anybody wanna trade [​IMG]
    But seriously....if anyone out there has some high power capability speakers and is throwing a piddly amount of power at them, you might want to reconsider.

    Oh yeah...and BTW....Rush 2112 makes a great test for your system!

    I had some Polk LS50's. Those speakers were so uninspiring that I almost got out of the HT game altogether. A host of bad memories come to mind everytime I think about them......OMG, here comes another bad memory.[​IMG]

    Rob, what are the differences in sound between that and using only a single Amp One in stereo?

    Well the single Amp One is only 80wpc, of course, although a pretty hefty 80wpc I might add. But, when I was listening at very loud levels I found the single Amp One to be near max power when powering the LS50's. These are 89db sensitivity, keep in mind and can handle 250wpc. For something like my Klipsch @ 96db sensitivity it prolly would have been fine. But, overall, very clean, clean sound even at very high volume with lots of power to spare.
    Besides...I got the two off of ebay for a combined $240 shipped to my house [​IMG]

    Rob,

    I agree I have a Klipsch KG HT. 5.2's as mains and surrounds. I use a Rotel RB-1070 and RB-985mkII with them and they sing. IMHO, nothing makes a speaker sounds its best like clean strong amps.

    Oh, so it was using the 89db speakers where it made the difference. Whew. I was about to ask about your hearing. [​IMG]

    Rob,

    Or an orange, potato, or any other electrical cell. Ever seen a clock powered by an apple? [​IMG] Seriously though, some people actually use 12-volt batteries (maybe the kind used in cars, or smaller) to power their amplifiers and other equipment. And I say the optimum solution to power problems is not to buy more powerful amplifiers but more efficient speakers.. well, I don't practice what I preach. My speakers are 87db.

    Seems to me I read somewhere that there is a trade-off when going with more efficient speakers. Can't remember what is was though [​IMG]
    Anybody ever heard this?

    It is amazing what a good amp can do.

    I had some old Advent 1's with a Techniques 120 wpc stereo receiver. I used it in the VHS Pro-Logic days. The results were ... so so.

    One Christmass, my wife gave me my first HT receiver: a 80 wpc Yamaha.

    Bravely, I un-packed the unit to hook it up (all the while planning to re-pack it and take it back for something 'better'/more powerful).

    I was stunned at the difference that the 'lower-power' receiver made. It was a whole new system.

    More experienced members have already done the math:

    Techniques stereo receiver, 120 wpc X 2 = 240 watts total
    Yamaha HT receiver, 80 wpc X 5 = 400 watts total

    Not all that power was available to just 2 channels, but the newer Yamaha had other quality improvements over the old Techniques receiver.

    See Rob. I run a Rotel RB-1070 with my 5.2's and love their sound. The 1070 is 130 watt/channel. I noticed at lower levels the speakers had more weight than with just my receivers amps
