probably a dumb question but how do i connect two amps to my speaks. i have an xpa 3 hooked to my frt 3 but was contemplating a biamp for my l/r by buying an addl amp. now i just need to know how the interconnect from my avr can feed 2 amps and if having 2 different brands would be ill advised

    Go buy a "y" adapter for left and right.

    Make that 2 "Y" adapters for L/R, which amps for what speakers?

    200 watts is more than enough for rti 10's no need to bi-amp unless you're running them at crazy levels. You might not hear a big diference.

    i read a couple of threads here about "vast" improvements in sound with biamp on the 10's. i searched the tweak forum and a few guys say that short of replacing these with a better speaker that biamping should help in 2 channel. i also just wanted to know how guys hook up seperate amps to the biamp terminals if the avr can only feed l/r individually, who knows, i may just unload the rti's and go with my mon 70's in the main room

    I would not bi-amp with two different brands. You can do it but I would not. The sound and gain could not match.

    Leroy is right about the Rtis and power...and this also applies to the M70s.

    Are you saying that you can't 'hear' a difference with a power amp running your RTIs? Because I can hear a pretty reasonable difference between running my M70s off a Denon 110 watt/channel receiver and a 200 watt/channel power amp...they sound so much better with the extra power!

    cnh,
    the rti's opened up a bit when i added the addl power, and the better i/c's and speaker wire, but... they still seem to be missing something to me. the sound is just tiring after short listening sessions and i don't think i'm getting a true reproduction of the original source, granted i'm using a ps3 for my streaming/cd player so maybe this is all a source issue. thanx for the replies guys

    ...since you need at least twice the power to have a minimal gain of 3db I believe...

    I would play with the positionning of the speakers before thinking of additional amp. Unless you mean tiring because you bring them up to a distosion level, I believe th tiring would more likely be poor placement, sound management etc... Try the simple and innexpensive fixes prior to involving money on extra amps. As I mentioned, you need to at least duble your amp power in order to see substantial difference. Afterall, you are not driving ALL of your speakers with a single AVR, you are already using an XPA3. Why not trying some amp reconfiguration at this stage? I gather you are using your AVR to drive the remainder of your speakers?

    Cheers!

    yes, i'm using my avr for the rears and surround rears. not sure what you mean "amp reconfigure" , and i know this isn't a dedicated h/t room so i have to live with the acoustics of the room, being the waf and all. i guess i'm just looking for a simple fix to my quetionable sound quality. i do try and push the system to 90dbs for short durations just to see the way the frts behave, so untill i keep adjusting and tweaking i have to live with what i have. i just found a good deal for some outlaw m2200's and wanted to see if they would make a diff
