Any love for newer Krell amps?

millercarbon-I really appreciate your sarcasm. You obviously are a very nice person (couldn’t resist emulating your sarcastic example).

Appreciate your projection. (See now that is sarcasm) But its called wit.
On which pjr801 has me beat all to hell:

A phone call from the CEO - priceless.

Brevity is the soul of wit.

I never engage in a battle of wits with an unarmed man.  

Miller,
Carbon posts are lighter than most other equally sized posts.

Would a Krell amp work with a Modwright tube preamp and Dynaudio Special 40s?

Here is my 2 cents - I have used Krell integrated amps for over 15 years. My oldest Krell KAV 400 xi just died. 

I replaced it with the new Krell integrated - K 300i two months ago. It uses the XD amp design and puts out 150 watts per channel into 8 ohms and 300 watts per channel into 4 ohms. It pushes my Maggie 1.7is very well. No fans are used to cool the integrated amp. I have a bigger sound stage and way more detail especially in vocals. My second system uses the Krell Integrated - S550i. This design precedes the XD design. The new Krell sounds better in my main system. 

Krell’s new XD amp design is an advancement -IMO - in quality sound. Per Krell the amp runs longer in Class A power before is goes to Class AB - and i can hear the difference.

To Krell’s credit - they tried to repair my 15 year old KAV 400 xi. I ran up an $800 bill on these repairs and the Amp was still ‘not stable’. They gave me a credit so I could apply it to their new integrated amp. I bought the new Integrated Amp and I cannot be happier.

you have to put a value on a manufacturer that stands behind their equipment and works hard to keep their customers happy.

Happy listening
