Any love for newer Krell amps?


I recently bought a Krell Duo 175 xd power amp, after debating between it and a less expensive Coda power amp.  I was not able to hear either amp so I based my decision on the recommendation of a dealer who sells both.  I’m liking the Krell very much. I’ve seen a lot on this forum about Coda amps but almost nothing about Krell.  Any Krell owners, enthusiasts or even detractors out there?

I’m looking to replace my 23 year old Krell KVA 300i integrated amp. So I am looking at the Krell Duo 175 xd, i’m wondering if it’s too much power for my Theil CS 2.25 speakers. Anyone out there have any experience and or advice? (There is always the Krell Duo 125 xd. Upgrading the speakers is another option but one that I can’t afford at the moment if I go with the 175.)

Other suggestions?

I have the KRELL K-300i integrated so I know the sound of the new XD line.

I am looking to upgrade a Parasound A21+ to the KRELL 175XD or 300XD. The A21+ sits right beside me when used as a headphone amp otherwise I move it further away in-between my floor standers. Can someone tell me if the KRELL cooling fans are noticeable if the amp is right beside the listener. 

My 175XD is a couple of feet from my listening position and I've never noticed any noise coming from the fans.  I was concerned about this before buying the amp but it's been a non issue.

Thanks. The only negative for me now is the 21-inch depth of the amp. I did not realize it was that big.

I have to decide between a new 175XD or a used 300XD. After I get rid of my Parasound A21+ it will be about the same price for the 2 KRELLs.
