Has anyone tried the ATI AT54XNC Class D amps?

If I like the At527NC I will purchase a second. the problem with the Rotel RMB-1585 is that is so large I could not fit it and a AT4007 in my AV cabinet but I could fit a AT527NC. I can fit both a AT4007 and a AT527NC.
Based on SteveH’s observations, he prefers the signature series (AT4000 or AT6000) followed by AT52XNC, and less for the bridged AT54XNC. I have the AT528NC and am quite pleased. Currently have a Parasound Halo A31 for front three but plan this fall to compare the two in stereo.
Edit: I did run my mains on the AT528NC for quite some time but did not do any careful evaluation.
