Any love for newer Krell amps?

OP. If you like it, you like it. Why not just enjoy? The only way to know if you like something else better is to try it in your system. If you do want to try something else and are shopping for opinions, then you'll get more constructive feedback by saying want you feel like you're missing (or want more of) with the Krell. Otherwise, congrats on your purchase. It's good you're not on here posting "what's wrong with my gear??" That's a win for both you and Krell.

I’ve owned Krell, and others, for thirty years. I can’t say enough good things about their customer service and sq, especially with the XD upgrade. Currently, I am pairing Krell 575 XD monoblocks with ML 13a, Don Sachs tube preamp and PS Audio as source. Always a joy. 

I'm a big Krell fan so hope company regains iold glory.    My audiophile  baptism was purchasing 1st Krell amp that was 25% of my gross annual salary but so many fond memories.   It was sad when Dan was kicked out ....   Momentum is my favorite SS amp and waiting for Krell to make one someday.

You simply cannot beat the performance of the recent lineup of Class A KRELL CD amps. Utterly musical and breathtaking ability to soundstage and present distortion free music.  Take it from a Krell customer who has owned the big “muscle cars” of their amps like the 400 FPB CX. So congratulate yourself for a great decision. 
My decision was based on hearing their new integrated amp at a trade show. At only 150 wpc it BLEW ME AWAY. So I proceeded to buy the 300 XD Duo AND their 5 channel 5200 XD. BOTH FAR exceeded my highest expectations. 

Sorry, but in reviewing I post I caught a minor typo. Sb “XD,” and not CD!  Enjoy the music as you’ve made a great choice.
