Krell K 300i Vs Hegel 390 Help

hegel will sound smoother
krell bit brighter bass sound bigger (but not tighter) than hegel
B&W speakers err on bright side, suggest Hegel over Krell

Actually, I completely disagree with this.  If you are referencing the new K300i integrated, it has the new Krell sound, which is very smooth and lush.  The highs are not bright or harsh at all, but very smoothed over.

The Hegel might sound a bit bright and harsh, to be honest.

The new Krell K300i is probably somewhat similar to the Vanguard integrated.  The Vanguard is part of the first Solo/Duo/Trio/Chorus line of amps.  These are also voiced on the lush/smooth side.

The older S-300i integrated is part of the Evolution generation of Krell equipment.  It is much cleaner and higher resolution without the amount of "bipolar Class A" type of lush/smooth sound that the current generation has.
