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 .

I agree with the others regarding Coda. Even though you have a preference for tubes (I have also for most of my life), try to audition the Coda No 16 amplifier. I think in this very recent review, the reviewer nails it; the best of solid state coupled with the best of tubes (for the far less costly Coda CSiB integrated) without the heat and cost of ownership (tube replacement).

Iv'e heard only good things about Gryphon , but I'm a bit fixed on tube amplifiers . I love there sound more than solid state amplifiers....
Thanks for your suggestion ! 
@haimr, 
Given your stated objectives and  desires I believe that the CAT JL7 is a very good choice for your short list. This is a tube amplifier that I feel could drive the Magico A3 quite  well.

The https://rogershighfidelity.com/ Rogers 34S2 or KWM88 are great. I use an 88 to drive inefficient speakers. These are intagrated amps. 

I mean you'd figure anyone with a pair of Magico A3s would engage a preamp by default, right? After all Magico recommends (at minimum) 50 watts / 4 ohms.
