Help setting up 2 amps at once with speakers??? Help

Hey guys I’m using a pair of Polk rti a7s with a Denon Poa 2800 amplifier and Denon receiver 2801. I just bought another power yamha PC2002M power amplifier which has a little more kick then the denon 2800. But I will be giving the denon 2800 to my dad when he gets back from his trip. I just want to know is it possible to hook up the 2 power amps to my setup at once ? And is it worth will I see a big difference in sound quality and performance ? I’m just curious and want to do a bit of experimenting only if it’s possible? Don’t want to risk blowing anything up. Thanks guys

Tony

    probably but I’m not familiar w/your gear. Either way take your time making connections & 2X everything before flipping switches

    Just pick the one that sounds best to you, sell the other or keep as a back-up.

    "Two amps, one pair of speakers" is an inside joke at another forum -- because the simple answer is "don't effing do it".

    That said, a "break before make" type switch will work satisfactorily.
    There must be no possibility for both amps to be "in circuit" at the same time if they're energized.

    There were (and still are) switchboxes designed to have a matrix of components -- Niles, I believe, may still make such gizmos.

    They were standard equipment in hifi stores in the 1970s and pop up more than occasionally at eBAY and whatnot.

    I have one of these, which is a simpler (and less expensive) version of the "comparators" mentioned above. This is more than the OP needs, but these aren't terribly expensive nor are they too hard to find.

    The only drawback to the Switchcraft is that it's built for 1/4" phone plugs (for amp and loudspeaker connections) -- so one needs to either buy or make 1/4" to RCA cables to use one. Not a big deal, but one other thing to take into account.

    I think he means in a bi-amp configuration. Which, all he needs is an RCA splitter for each side....and more rca cables.

    Though I'd still advise against it. Either amp is more than enough for those speakers. If better sound is the goal, start looking elsewhere in your system, quality of the cables, source your using, pre amp, dac, etc. The Denon receiver isn't doing you any favors, musically speaking,

    From personal experience I’d strongly advise against it. I blew a really nice amp trying to do something similar. I can’t imagine that any benefit would be worth the risk.

    I don't think the OP is quite as advanced in this arena as you... as a matter of fact, most of us aren't! You've done quite a bit of customization with your rig. Hence, the advice to the OP... Don't do it.

    Maudioguy: most humble thank you
    and...
    Does his AVR have pre outs? Does the sep amp make robust power like a P’sound, Rotel, or B&K?

    Derp. Guess I should actually read (or at least, striven to comprehend) the first post's text, eh? :/
    My apologies to the OP.

    Is it possible to use a integrated preamplifier with a power amplifier ? In my case an integrated preamplifier with my Yamaha or Denon Power amplifier ?

    Are we talking stereo (two channel)?
    The answer is (AFAIK) sometimes. It should be possible if the integrated amplifier has "MAIN IN" "PRE OUT" jumpers or jacks on it -- or it might be possible if there's a "PROCESSOR" loop. The 'breakpoint' needs to be after the preamplifier section in the integrated (so that the volume and source selectors are active, as well as any other preamp stuff one might wish to use -- tone controls, filters, whatever).

    A - vintage - example would be the Yamaha CA-810.

    the PRE OUT/MAIN IN jumpers are visible at the lower left in the (borrowed) back panel photo of a CA-810 above.

    Possible....yeah, but why would you ? An integrated is simply a pre amp and power amp in one unit, and you already have the power amp.
