cayin A70T vs. Rogue Cronus vs. Prima Luna PL2

I am considering a tube integrated to run some Harbeth M30s (also looking at Ayre and other ss, but leaning toward a try at tubes). Read good things about all 3 amps, but wonder if anyone has done a head-to-head?

I'd pair the Cayin with a Cayin CD player, and the Prima Luna likely with a PL CD player, no idea what I'd use with the Rogue. Am open to suggestions for all. Want to keep things simple and also aesthetically pleasing in a nice secondary 2ch system and my first foray into tubes (other than an old Fender Twin and a few other guitar amps).

Would consider others (Cary, etc), but these seem to be so well-reviewed...

Thanks for any comments.
