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 hybrid suggestion: Absolare Integrated. I've only heard them once at a show but they sounded very good, very natural.

Am I mistaken?  One poster says he runs his tubes mildly, imp-lying there is less heat.  That is incorrect, isn't it?  For Class A amps. too!
Atmas are, literally, 1 SET per channel functioning in push pull mode.
This is a contradiction in terms. 
jjss492 is absolutely correct haimr,

running a tube amp with speakers that have a 4Ω impedance and are only 88dB efficient is swimming against the tide. Running a tube pre-amp with a H.Q SS amp may give you the sonic signature you're looking for without the hassle/expense of tubes.

Any idea the number of tubes you're going to go through driving that kind of load?

I suppose you're over 21 so you're going to do what you're going to do. I'd recommend the Antique Sound Lab, Hurrican. 200 watts of juice, they're reasonable priced, and with your budget they'll be plenty of elbow room left over to buy tubes. https://www.hifishark.com/search?q=antique+sound+labs+hurricane
