Pass Labs' X-Series gets my vote over Classe, Krell and ML everytime as long as similar priced items are compared. The Pass X series X250 and above will have no trouble running the Maggies.

Having owned amps from all three manufacturers, the Pass is a walk away with the other amps seeing nothing but tail-lights and dust. As Bigkidz mentioned though, the Pass needs to remain powered up at all times to really sound its' best. You can try powering it ( or other similarly biased amps ) up and down as needed, but Bigkidz speaks from personal experience. How do i know this ? I remember when he first asked the same question himself : )
Honestly though, it's a good thing that he mentions this here as a reminder though, as one might not be quite impressed or ever really get to hear what the Pass is capable of if one based their findings on an amp that was being cycled on and off as needed. Just bare in mind that these amps DO run hot and need adequate ventilation. They will also pull a good amount of power, so look at the big picture when shopping for amps. There are very few amps that run as cool or draw as little power as the Sunfire's, so be prepared when making the change. Sean
IMS sytem consist of andra,art audio preamp,siltech wire,
ps audio 300, the pass did not even sound musical at all
very dry, it generate reasonable heat, compare to Krell
the heat of x250 is nothing,then I return the x250 to
my friend,who has thiel CS6,then again is not musical at
all but it sound good, compare to the extreme stratos
oddyssey, the extreme are musical in my system, and magical
with the thiel,GUEST WHAT?He sold the x250.I will both
try this 2 amps before buying.
How does an amp not sound musical? I just don't understand that popular term. Dry? as opposed to wet, I suppose?
This is what I get from the Pass amps I have owned. An amp that gets out of the way of the music. The music is generated by the front end, not an amp. Sure, an amp can ruin the music, through distortion, and purposeful coloration.
Pass amplifies as purely as is conceivable. All the tiniest nuances are clearly transmitted through my reference grade speakers. I am spoiled.
I use a tube cdp. Each tube is laid bare for any defect, the Pass system is so good. Luckily, there are near perfect tubes available.
