Krell New Pre-amps?


Hi, has any one auditioned or own any of the new Krell pre-amps?, if so, How does the best from krell stack up against The krell KRC-HR and KCT, and anything else Krell has ever made for pre-amps?, also, what is the favorite Krell pre-amp of all time?, Thankyou to all, I thought this may be an interesting subject for everyone to chime in on, cheers.

The pre-amp section in my Krell Evo 707 is fantastic, much better than the Krell KCT, my prior pre-amp. The comparison is not even close.
Thankyou for your reply JMCgrogan2, very interesting your post is to me, I have never listened to a Krell KRC-HR, so you was a great asset, with a good explaination.
Matjet, when was your evo 707 made?, is that a home theatre proccesor that is a pre-amp as well for two channel?, what was the sound that you did not like with the krell kct?, cheers.
