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 heard them at a 'Vegas T.H.E. show (around 2014) and liked them VERY much. Excellent solid-state amps.
Well, with the newer models, the expensive heat sinks of some of the more recent previous models have been replaced with fans, many don’t double down into 4 Ohms, and none are rated into 2 Ohms anymore.
So what were the differences between the CODA (#8?) and the Krell 175xd that made you choose the Krell. I gather for the KEF Reference 5?
