The A-400x is worthy of distinction in every respect. With its no nonsense styling approach, nothing else in its price range offers such a persuasive combination of abundant power reserves, ultra – detailed transient reproduction, and authoritative deep bass response. Inside, you’ll find some of the world’s most advanced amplifier circuits, providing 200 watts per channel (8 ohms) with the level of sonic purity unmatched by any other amplifier in its price range. We recommend the A-400x for main speakers and home theater systems, or for forceful subwoofer sound in mono mode.

    What is bridging mono power? Also, how do you bridge? And what does it mean to bi-amp., and can this Carver A-400X be bridgeable and bi-amped?

    I have a Carver A400x amp with about 30 hours on it (wife didn’t like surround-idiot) Also have manual. I am wondering what it’s current value is.

    Hi I have question does this amp get really hot. I have a pair of KEF q7’s and I want the
    To biamp them with this amplifier and onkyo 609. Is this a good musical amp. I have heard it gets burning hot.

  11. Chuckster says:

    Carvers aren’t ‘burning hot’ amps…it’s not the way Carver designed/designs them. If anything, it’s a quite a bit cooler-running than ‘class A’ amps of the same power range…I know, I had a Pioneer SPEC-4 and the Carver both. Once.

    BTW, if ANYONE has a good M400a Cube amp and / or a Phase Linear 4000 MKl (with the joystick for front/rear spkrs) and is willing to trade for some DJ-quality amps and a Carver SS pre/tuner, please let me know at cmk59@yahoo.com. Thanks!!!
