Krell Fpb400Cx vs AR Vt-200


I currently use a pair of the Krell Fpb400cx Amps and I have a chance to get a AR Vt-200. This would be used on the mid/high panels of my Infinity IRS Betas. Would this be an improvement over the Krell. The concern is would the Ar provide enough power. I know the panels are power hungry and also the issues with tube Amps, maintenance, tube life. Thanks for any opinions.

IMHO, the Audio Research VT series was not of one of AR's best efforts.  I do not know what kind of power your need to drive your mid/tweets, but I believe that you can do much better sonicly than a VT-200
The VT200 should be a-ok on the Betas - 200 watts of tube power is fine for the mid/high panels.
