Which amplifier should i buy


Hi,
Iv'e already asked , quite similar question , but i would like to clarify my question. So , Iv'e ordered a new speakers, Magico A3 and now i want to buy an amplifier, a tube amplifier. The amount of money that i can allow myself is up to 20,000$. The possibilities that i thought about are : zesto eror 300 / vtl MB -450 series ||| signature / vac phi 170 (two - i mean transform it monobloc) . Those are the options that i thought about till now. Does anyone can recommend which is the best option in this amount of money , it doesn't have to be from the option list that i mentioned.Unfortunately  there are brands that i can not buy in my country (ISR) , for example cat....
Thanks to anyone .

Ayon make excellent tube gear if you are set on tubes 
they have the only true microprocessor biased amp 
not fake self bias that averages all tubes .
the Ayon individually calibrate each individual tube for optimum 
stability and longevity. If a tube goes it goes into stand buy 
instead of possibly taking out a transformer then just run the rebias and 
you are back up and running.also they use Worldclass Lundahl transformers and chokes ,which is the heart of any tube amplifier.
Hello,
I have a preamp lampizator subminiature (lukazs fikus) with a sony ta-5650 SS (v-fet)
The sound of the V-fets transistors is similar to the triode, the combo preamp valve and power amp SS is better than my mc-225, the sound is more fast and natural!
May I suggest Audions by AGD Productions. New gallium nitride transistors. They sound good into my Acoustats 2+2's.
