    I've been comparing the two for a while now, and I was woundering how the TB community felt on this subject.
    I have played thru a Crest CA9 and a QSC PLx3002 for an
    AB comparison, and there is a difference in girth and sound.
    From this test I would have to go with the heavyweight
    amp. I'm still experimenting with other amps but, so far the
    heavyweight are ahead as far as sound goes.

    weight nonwithstanding, i'm pretty sure it has more to do with the particular "class" a power amp is built upon, than how heavy or light it is.

    I'm not sure about this but I believe that regardless of weight issues, the better power amp will sound better than the cr@ppy one.

    Lightweight with good quality. My back agrees. :D
  5. The best sounding power amp I've heard is a Crown Macrotech and it's real heavy.

    Which sounds better, lightweight or heavyweight?

    That's like asking "how long is a piece of string?"

    Unless you match the gains precisely, the louder amp will tend to sound better, with the same program, speakers, et al.

    I think generally it would be lightweight amps, because they are usually designed and engineered with greater care.

    I'm with GreyBeard. The Crown Macrotech and Microtech 2400 is my all-time favorite.

    Now now people, you're doing it again!

    Read my sig.
  10. Well, I can answer that Bob.

    It's about 34 inches, plus enough to span the bridge and pegs.


    Oh, re: the power amp thing. I was involved in another forum discussion regarding 'switchers' and 'lead sleds'. Funny thing is, one of the most collectively experienced forums (pro sound web LAB) did a subwoofer cabinet shootout. Their favorite poweramp, to power the sub cabs, was a switcher (QSC PL series). Knowing that they could have used virtually any type, brand etc. of amp for the shootout, it was interesting that they chose a switcher. Bob, I think you're familiar with the shootout, and choice of amp that I'm referring to.

    I personally use a lead sled to power subs in my band because:

    a) I need the exercise
    b) I ain't got the coin (about double) for an equivalent powered switcher

    Pete, I'm listening for the sound of your post, but I'm not hearing it. Only seeing it. What am I doing wrong?


    Oh, BTW, I agree. ;)

    Turn your speakers on silly!
  13. Ok, my take on the 'question at hand.'

    All things being equal (and they rarely are)

    -atmospherics - temperature / humidity / barometric
    -your state - of - mind,
    -& stage

    will impact what you hear ....

    ... moreso than the power amp.
