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 .

@haimr we're a Magico dealer and have tried a handful of tube amplifiers with the Magico S- and A- series speakers.

I know someone who is using the S1 MkII with a VTL ST-150 and is very happy with the combination. I've also tried the VTL S-200 Series II and Audio Research ST-80 SE, and they both worked well. I can also recommend the VAC Sigma 170 iQ and PrimaLuna Evo 400 power amplifier as both being able to drive the moderately difficult load presented by Magico speakers better than some other tube amplifiers.
Have you considered a hybrid amplifier?  One with a tube input stage and a solid state output stage.  The ones I've owned are made by Audio by van Alstine (FET Valve 600R) PS Audio (BHK Signature 250 and 300 monoblocks).  I've had high powered tube amps (e.g., ARC Ref 110) and high powered solid state amps (e.g., Bryston 4B SST2) and the hybrids seem to combine the best of both worlds for me.
@nekoaudio 
Great advice's , Audio Research seems to be very interesting, i though about the reference 160 s stereo amplifier and about the vtl.
Thanks a lot !
