Pure Class A SS vs Tube Amp

Prima Luna are great amps, made by  Spark ,,,I perfer Spark's own line Cayin,,,for a  better price and almost same  design, but i perfer Cayin's design.
which Prima  Luna do you have?

@mozartfan I have an EVO300 integrated, currently with stock tubes. But not for long :-)

Seems like with gain complications I’m still not going to get great benefits with Michi P5 and passlab first Watts J2 ?

Any of the Pass Labs  XA amps would be a great fit for your system. You can get one here and other sites and the resale value is great in case you decide to go tube.  You would be doing yourself and injustice if you don’t try a Pass Labs amp.  

Now I’m thinking about XA 30.8
since eventually I may move to focal Electra 1038 when my 4 months twins grow little bit 
I want separates and I really want to keep my Michi P5 Preamp gain is complicated with first Watts J2 
the question is passlab XA 30.8 is better than Parasound A21+
