How much better is the Krell 400xi compared to the

I have had both and plenty of other amps, my question is has anyone made direct comparisons between the 300i and the 400xi?
They are both terrific units but other than the 50w difference which is not really vital for me based on my secondary system driving high performance monitors...difference between 300i and 400xi side by side listening anyone? :) thanks

Is it worth then buying a used Krell 400xi over a used Krell 300i ? The difference is probably about $750 to $1000 ?

How's about the re-sale value? Currently, 400xi listed for 1600.00 uo to 1700.00 with 1 year or less of usage. The discontinued, vintaged 300i listed average 1100.00 with average 6 to 8 years of usage. It's the question of re-sale value and the marketability of the current unit vesus vintage unit. Don't we have the upgrade desire every once a while?

Dave29:

The manufacturer rates it a 200wpc/8ohms. How can it be rated higher by someone else?

I am looking for a new amp. I now have a Jungson JA88, chinese yes but amazing value for less than 1.000 Euros...I was wondering if a Mc MA6800 second hadn would be something but reading these comments on Krell make me doubt. Over here Krell is often assosiated with little refinement...
