My 2 cents: it will be very difficult to get tube-like sound from a SS amp without paying $$$. I had a Cayin CS100a which I sold and I briefly tried SS amplification for the same reasons (no more tubes, less maintenance, etc). After 3 months I sold the SS amp and bought a Qualiton X200. I get the concern about the prices of tubes now, I purchased a Tung-Sol quad KT170 for $450 in December 2021, the price now for a quad KT170 on Viva Tubes is $1,600!
I really hope that the lack of supply will be a temporary situation and that tube prices will go back to normal after the madness of the war is over. Time will tell, I'm just glad that the rest of us are living our lives in safety.
