cool, would be good to get your take on it.  there's a long thread on audiocircle I think about it.. I hear the speakon connectors are better than the banana jacks

Yea. I know it got a praise and popular cause guy on avs forums. Said liked it as much  or better than his parasound halo a21 with his b&w 802d speakers or something . I don't know. I know crown been working on class d tech since the 70's. That's how they developed their "class I/bca (balanced current amplifier)" amps. The drivercore series is I believe collab of crown and texas instrument. They use a specially designed chip to track the class d ouput stage to keep crossover distortion very low. They have the xti series which are like hybrids (class a/b output stage with heavy duty t-03 transistors and class d smps power supply) untill you hit totl in the series which is the xti 6002 which in it's case a class I/bca design all around like the bigger I-techs and Marco Tech I's.

I'll let people know how I like crown's class d xls 2500 when I get mine sometime beginning of next week.

I also can agree about the speakon connectors.  I love them. 40 amp current handling, easy to use (basically idiot proof) and makes things so much easier with plug and play/quick speaker swapping with no risk of shorting anything out. One reason why I like pro amps. I doubt consumer gear ever adapt it except maybe for some marking thing maybe (even though I'll like see speakon on all amps of all kinds).
