    The only one that comes to mind are the discontinued Crown K series...are there any others? I play some smaller three piece gigs once in a while and it would be nice to have one rig that can cover this nice and quietly

    I need about 500 watts a side at 4 ohms

    Just a thought, I wonder if an alternative is an amp with a multi-speed fan. For instance, my GK head has a 2-speed fan, and for virtually all playing, it runs at the low speed and is silent.

    Stewart World 250/600/1.2 are all fanless, convection cooled power amps that take up only 1 rack space.

    I gotta do some searches on these Stewart amps, but to get to the point: do they bring on the beef?

    You'll want to read the entire "QSC PLX versus Crest CA9" thread for an exploration of whether switching-supply amps bring the beef any differently than traditional big-iron amps.

    I certainly was not disappointed with the two World 1.2 amps that I had in the past. :)

    BTW, I had a World 250 that was fine, also; the guitarist in the band is using it with his POD as his guitar amp now.

    Look for a bridgeable studio monitor power amp.
    Most are actually reasonably priced.

    I would seriously recommend this one, I know several guys using this one....

    Alesis RA 500


    For the cheapskates, there is of course a Behringer clone available...

    However, if only the best is good enough, this one just kills anything else in terms of quality and sound...

    Glockenklang Bugatti


    But I guess, for your application, the Alesis is probably the sensible choice ... :)
