Krell KAV-400xi, how good is it?


Hi
My current system consists of:
Krell KSA250
Krell KSP-7B
AudioNote DAC2
Jadis JD-3
Dunlavy Alethas
Not so hi-end cables
I actually is planning to replace my KSP-7B with a tube pre-amp such as Sonic Frontier SFL-2, until I read the Stereophile magz Feb 2005 issue regarding the new integrated-amp Krell KAV-400xi. It says "My favorite krell ever" !! Is it really that great? I am just thinking that by investing approx. $1000 more (after selling my Krells), I can get a brand new 400xi. My question is: Is the KAV-400xi better then the combination of KSA250 + Sonic Frontier SFL-2? I could not compare them as I have no luxury to audition the KAV-400xi. I have tried the KSA250+SFL-2+Dunlavy, I am actually quite satisfied with those combination, but they are old!!!
Please help me, thanks so much.

HI!
IM NEW IN AUDIO, I HAVE A COPLAND CSA8, AND MY RESELLER OFFERED ME A KRELL 400XI, WORTH THE DIFFERENT?
I DIDN`T HEARD DE KRELL.
THANKS
I had the Krell 300i which I used with Dunlavy SC-III's for years. I always enjoyed it. Last year I got a Primaluna Prologue 1. Since that time I haven't hooked up the Krell. The PL is much more musical, bigger more 3 dimensional soundstage, more natural sounding. The mids are incredible with the PL when compared to the Krell. I am hearing things in the mids I never heard with the Krell. The only thing I lost was a slight amount of bass punch. I have never heard the 400xi and it may be completely different from the 300i so my experiences may be pointless for you. I thought I'd throw my experience here since you are a Dunlavy owner in case it helps.
