could someone compare krell vs. classe audio ?

I own Krell and have listened to Classe a few times at shows, dealer show rooms etc. The "choice" really depends on what level in each of these manufacturers lines we're talking about. And especially in the context of the system you're considering running them in. So the answer depends. Top of the line Classe probably brings more to the table than the low end of Krell's line, and visa versa. And what sort of load are you asking what specific amp model to drive and interface with from the pre/source level? Both are top quality manufacturers; their engineers have done their home work and woodshedding to produce what is generally the state of the art on solid state amp design, otherwise they wouldn't still be around after all this time, regardless of what the bashers may think, if you can call that kind of sentiment actual thought to begin with. And there are other manufacturers worth considering as well. Depends on what you have, where you're going and what you want to achieve. And by "compare," what are you really asking? Otherwise you're likely to find this thread dying on the vine. We goners want to help but these sorts of thread starts are a dime a dozen and it's much more fun if there is something to "bite into and chew."

My opinion since I am using older Classe' gear is to go with the older DR series.

I can vouch for the reliability of my 15 year old Classe DR 8 amps run in mono.They are working just fine and sound as good as most of the more expensive solid state out there. Not looking to change since I've had these. I've had plenty of tube and solid state amps these are keepers.

Mapleleafs3, lighten up, dude! You've been a member here for one month, no threads initiated, no feedback, and your multiple posts sound like regurgitated dogma! In addition, some of your comments are abrasive and border on obnoxious. Agon long timers have seen newbie "flash-in-the-pans" come and then vanish, shortly after engaging in their personal "mission" known only to themselves. Hopefully, you won't be one of these.

Personally, I do happen to agree with your opinion about Rouge amps and Coincident speakers. But some of your other comments are way WAY off base.
