Krell 300 il or 400xi or ? What would you do ?


I think what I want to do is get a pair of Magnepan 1.6 for my fronts and use my MMG's for the rears. I like what I am hearing with Magnepan.
I want to use a Integrated amp. The Krell 300il seems to be a good canidate and or the 400Xi.
Trying to understand why the 400xi has a lower list price but has more power then the 300il that has a higher list price but offers less power?
What am I missing and not understanding in these 2 units.
Open to suggestions and help on this.
Thanks,
Dave

The 400 is fast, detailed and powerful. Precise, but a little cold. Taut, controlled bass. It's a Krell, you'd expect that. I've got one. Stereophile did a review several months ago. The only knock on the 400 is that the heat sinks are inadequate. So if you're driving the amp pretty hard for a long period, say at a party, you'll get some distortion. I've never experienced this, but I don't have big parties anymore, either.

I've not heard the 300.
In my system/room the Krell 400xi comes across as neutral and if anything a bit warm but very smooth/rich/robust. The new list price is $2,750- Which is still a steal considering its sound/power, reliability/warranty and gorgeous looks.
