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 .

Another vote for tube preamp and ss amp. I have Cary SLP-98P F1 and modied SLP-05. Either one driving a Pass amp sounds excellent. 
I’ve read that also about the BHK mono blocks. And do know that I’ve never had them go into protection mode on my Magneplanr 3.7i’s. Could be I just don’t push them hard enough I suppose. 
Thanks a lot to all of you, you really gave me lots of great suggestion and i discovered new and interesting amplifiers . I've already decided that ill go for the CAT JL7SE .
Thanks again to all of you here for your great attitude and your will to help !!!
@haimr, 
Congratulations and I believe that you will be happy with your choice of the big CAT😊.

If I were in your position I would get the McIntosh MC2301’s and never look back. They are 300 wpc, McIntosh reliability, and last I checked come in right at $20k.

The only other high powered tube amps I’d put against the MC2301s are 1.5x - 2.0x the price, being the VTL S-400 and the Conrad Johnson ART300s.
