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,

Research dave_b and his take on the difference between the Krell 400xi and the Vanguard.  I don't believe we're off topic here.  Research, research and listen for yourself.  Why regurgitate all of this when there is great insight that exists within these forums?  Best regards.

What's the difference between the two amps?

Price.
Power seems to be the same.
Ok, so the question is whether or not the Krell Vanguard is superior to the 400xi.  Well, yes in absolute terms and no if you are strapped for cash.  Overall the Vanguard is clearer, more dynamic and slightly warmer.  It also will not overheat and produces a more fleshed out soundstage.  Bass has more texture and sounds natural as compared to the 400xi's taughter, leaner presentation.  Both are great values and outperform the competition by a wide margin, IMO.  FYI, Audiophileliquidaters have the Vanguard priced well below msrp!  
I'm going to pick up a used 400xi and do a shootout in my system!!  Stay tuned...the looser gets posted on Agon:()
