Is there Really a difference between a Krell 400xi intergrated amp and the newer Vandgard?


I currently own a Krell 400xi intergrated amp. It has 200 watts a 750k toroidal, balanced inputs, etc. Its very similar to the current vanguard intergrated amp in terms of similar spec's. I would like to know if anyone upgraded and if it was worth it? Is the sound different does it go lower, deeper, more of an open sound stage or should I just consider another route to improve what I already have.

thanks,

I agree Brian, I tried them all as well!  

Octet11, I highly recommend Music Direct...they are a class act and you can return anything you don't like after a thorough listen.
No cast connections on the Vanguard.

Also something of note, there are no pre-outs so if you want to run subs via rca, it's a no go.
