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've had 3 Krell amps, last a FPB600.  Familiar with 300i that I find 2D and hard.   I have a Hegel H30 and it's light years ahead of the Krells I had.   All Hegel I've heard is far from hard and flat sounding especially compare to 300i.  
Krellman is right. I have been pretty much a Krell user most of my time with this hobby (although not having the illustrious models Krellman has used) and the current Krell gear is very differently voiced from the older Krell gear. The Vanguard is in this new vein - more musical and forgiving, less visceral. Most importantly, the traditional bass slam that Krell is known for is no longer there. In the place of that is a more textured bass. Highs are slightly rolled off (not such a bad thing with some recordings), PRAT is no longer as good and the sharp transients and leading edge is much diminished. I am referring to the older main Krell line (and not the KAV line which sounded lighter and leaner). The FBI would still have the older sound. It really depends on what you like.

Just my 2 cents.
Excellent point- mikey8811
some of the newer Krell is made in china as well.
I finally talked to Patrick Bresnahan at krell,  he said the departed x president bill Mckeagan is what happened to the vanguard,  no pre-amp out,  no tape loop,  and ahh, the terrible voicing! , Bill did all this to attempt to save money and bill had the vanguard made in China! , my opinion,  what a way to shoot your self in the foot,  didn't save money,  promoted a lack of sales, and more than any thing,  no long term ownership! , have all of you seen the vanguard on the used market? , LOL!, there is no modification available!
