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 .

Those new Merrill Mono blocks with the Gan tech are getting great reviews. I think they have an INT available. Call Merrill. Smart guy.
in NY or NJ.
Sorry, no input, can't relate...for 20k I can almost buy a new compact pick up truck (about 24-26k)😳
And I thought spending 6k on my speakers was expensive...what do I know...they sound good to me.
