Well, there are several schools of thought on power amps. One school is interested in low cost and light weight while still providing excellent sound. The champs in this category have been the QSC PLX and Stewart World lines. The Crown you identify is a new player and looks really nice on the specs. The four items I would be looking at in this genre are the QSC PLX 2502/1802, the QSC PLX 1804, the Stewart World 2.1 and the Crown XTi 1000/2000.
The QSC xx02 amps are 21 lbs and all around great performers in the $800-1000 price range.
The QSC 1804 is the light weight champ at 13 lbs and about $700, but doesn't bridge and lacks some of the nice filtering features found in the xx02 series.
The Stewart gets great kudos for tone, but lacks speakon outputs for convenience. It's a middleweight at 17 lbs and can be found in the $800 price range new.
The Crown is the definite price leader and has some funky digital effects built in. If not needed, this new tech seems like a risk to me. The software to manage it is just coming out now.. Also, they only have XLR inputs, no 1/4 at all. That just means some converter cables, though. These are middleweight at 17 lbs.
The other genre is the I want THE tone at any weight category. Crest seems to be the king here with the CA series amps. Either that or the super-expensive boutique tube amps. These things are in the 50 lb plus weight class.
On a budget, there's also the Carvin DCM line that gets some praise. The DCM1500 is about the same power as the Crown 1000 and 34 lbs, but is only $399 factory direct.
With the exception of the Crown XTi, these have all been on the market for long enough that they can be had used to save a few bucks.
