Looking to move to a Tube Integrated setup

I have a Ayon triton Evo and completely love it. I only have one recommendation and that is go with KT 170 tubes. 

Had a Cronus a number of years back, even with NOS preamp tubes it just sound solid state to me; may have been the KT90s power tubes which it came with at that time .

Maybe consider looking into the lineups of Line Magnetic , Trafomatic and Finale Audio as well.  In my main system the speakers are Daedalus Argo V2s 97db 5ohm flat impedance and drive them easily with either a Line Magnetic 518IA (newer model is 845IA) - 845 power tubes 22wpc , or a Finale Audio 7189Mk2 - EL84M or 7189A power tubes 22wpc (I also at times use a Modwright tube pre and ss power amp)

With your budget you can probably go separate call Aric audio. My friend own MOAB he love his Aric gear.

You may want to consider a pre - owned Rogers High Fidelity tube integrated amp they offer direct w/ their full lifetime warranty. They offer a free home trial too. I compared their EHF 200 Mark II to the top Prima Luna & it was in a completely different class in every way & bought it. It’s big, heavy & built extremely well but most importantly sounds excellent! I have no experience w/ Ayon. 

Of the two, despite the beauty of the Ayon, I would go with the Prima Luna's. There are a lot of good points made by Kevin in that video. I've heard my friend's Prima Luna Mono Blocks on his JSE Infinite Slope Model II's which I helped him get/setup (I owned/loved mine for years), and on his current speakers which he prefers, I forget the maker, but they sound terrific, we both prefer tubes to his prior SS. 

Running them cool for long life combined with the adaptive auto-bias dream feature, makes me want one, my early Cayin has manual and dangerous internal bias adjusters. 

Spare tubes should always be on hand, you would only need a few, I gather that they will come with KT120's. As it is a major shift to Tube sound, I would encourage you to buy (now or eventually) a batch of EL34's, and compare them.

Break in new tubes: on, no input needed, just leave them on for around 60 hours is what Brent Jesse advised me to do.
