Ok, so you are using a 2 channel Amp at 125/watts/ch...

What is it you are trying to do? It sounds like you are thinking of bi-amping your speakers?

If so, what type of speakers do you have?
I have a set of nht 2.5I speakers that I want to bi amp.I would like to use a nht sa 2 amp or something similar.

BTW I know what you mean about the dogs I have 2 pugs

You could try using your Yamaha receiver’s (which model?) L/R amps. Since the 8” woofer in the 2.5s are crossed over fairly low at 100Hz, less power is required to drive them than the upper frequencies of the midrange/tweeter. I’d try using the B&K for the upper section and receiver’s amp for the woofer.

But truthfully, I wouldn’t bi-amp at all and just go with a more powerful amp.

I would have to agree. I had my speakers bi-amped with a Yamaha v3900 when I trialed the unit. Sure, it sounded better than the single amp, but the single was only giving me 140 watts/channel when running in stereo. Bi-amping gave my speakers more power and therefore I thought, wow, bi-amping is great.

I then upgraded to a dedicated Emotiva XPA2 and didn't bi-amp. The Emotiva is 250 watts/channel.. It sounds better than the bi-amped Yamaha. Just get a better Amp and you should be fine.

Doesn't that make your two channels dominate over the overs when your running 5.1 or 7.1 or did you adjust your channel levels accordingly . Im thinking of getting The XPA 2 or 3 thats why im asking .

A lot of 7.1 receivers today allow you to re-assign the 2 amps used to drive the extra 2 channels if you only have a 5.1 system for bi-amping. Unless you have the same 3 speakers as your fronts, bi-amping your mains is fairly typical. Most people use different center channels and typically those center channels don't require as much power as the mains.

As Adam said, if you level match them, you should be fine.. Now if all 3 are the same, then that's a different story. The power should be the same...

If you listen to a lot of stereo music, the XPA2 is supposed to be a much better Amp than the XPA3. It has more dedicated transformers and is supposed to bring out subtle nuiances more easily at lower volume levels than the XPA3..

I'm using an XPA2 to drive my mains and my reciever to power the center and rears. Everything is level matched. I had the same misconception and Adam and PDawg helped me clear this up. A good Amp should deliver clean power to a speaker. As long as the same speakers (your mains) are getting the same amount of power, you should not hear a difference in your surround modes.

Thanks Im leaning towards the XPA 2 now that you've explained to me its more clear figuratively speaking : ) The Only thing is my center channel is a cc690 whitch is pretty massive and I think would utilize the extra power more then my 60's that are my left and right channels .My center is probably equivilent to studio 100's im guessing .

Wow... that's quite a Center. My Center is big, an HTM1 B&W but it is no where near the size of my Mains 802's. You may want to do an XPA3 then.. I'm curious to see what some of the other guys recommend, but that Center is pretty beefy. Maybe time to upgrade the Mains??? :D

UGHHHHH Nooo dont say that :p lol Ya my center ways in at about 70 pounds and is rated at a amplifer range of 15 to 300 watts were my 60's are only rated at 15 to 200 watts . You know I guess I could upgrade to 100's and use my 60's for rears and go to 7.1 :D Actualy not lol I wish but i've I got bigger fish to fry im in the process of upgrading my sub and then possibly the amp .

Such problems, huh? I'd stick with 5.1, I think 7.1 is overkill unless you have a huge room. The idea of eventually using those Mains for your back, is a good one. Then you could just upgrade the mains to match or go a little larger than your Center...

I know but I just upgraded my rears to the adp 470's and there incredible for rears, I mean they really sound very good for rears and even in 5.1 stereo . I guess I could always move the 60's to the bedroom or sell them on audiogoN . But there no slouches either , I've had them cranked up pretty good and never showed any signs of destortion with my ELITE 94 130 watt pushing them . Guess I'LL Worry about that bridge when im ready to cross it and just concentrate on my sub and possible amp upgrade .My room is pretty small for 7.1 but I was running that for a while before I passive bi-amped my fronts and it sounded pretty good to so thats still another option I guess .

The simple solution is to do an even trade. Give me the 690 and I will give you the 590.

Otherwise, that 690 will need an amp. I am just trying to save you money!

Hey TheFactor,

I'm thinking, ok I'm voting that you save up for 3 channels of amp, if you're going to do it. That way you will never second guess, or worry, and it might allow flexibility in any speaker changes/upgrades in the future.

I've been buying all sorts of crap like a bat out of hell the last two years. Everyday that passes by, I do understand a bit better why there are those who say do it right, do it once. I tried my best, of course, I think everybody does... but that's where my "vote" stems from really.

Also, (forgive me if there's a different pic that I missed), but, I might consider (depending on present height of display, height of your eyes, how far you sit), getting the TV up higher to allow the center so sit on top of shelf (whether building something, or actually placing it on the center speaker). I think you would love the improvement to center speaker audio by getting it off the floor. Mine is low too, and I put a lot of absorption on the floor. My center is actually sitting on a treatment, which helped a LOT. still quite compromised, but I do what I can. It's the midbass that one would want to aim to absorb in this scenario.

Some speakers can handle TV weight. Contact Paradigm and see what they say. I know I've already helped someone at AH in deciding to do exactly that already.
