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 .

One more vote for Atma Sphere MA-1. They are driving my Sound Lab A3 (which are much more harder to drive than your Magico A3) and I absolutely love them. I prefer Atma Sphere over EAR Yoshino, McIntosh, AR, Prima Luna and VTL, mentioned here. 
Try a tube preamp into a solid state amp.  Try a tube preamp into a decent quality Class D amp, even something like Icepower.  You might be surprised. 
Interesting thread responses. The OP has written several times he clearly prefers a tube power amplifier.  It seems many disregard his taste and recommended 'their' preferences of transistor amplifiers.

Now that you have seen opinions from everyone else, I'll add my 2 cents.

For considerably less money, I strongly suggest that you look at the UNISON RESEARCH   "UNICO 90 or the "UNICO 150". Hybrid design allowing reproduction reflecting the best of both worlds. I consider these to be "musician's amplifiers". If you desire to spend more, consider their monoblocks and preamps. 
Carver 350 monos will handle any speaker you throw at them.  And at under 10 grand you will have money to spare to change out the signal tubes to NOS.  The power tubes are kt120's and with Carvers DC restorer circuit they run very cool and have huge long life.  I believe they warranty the tubes for 10 years.  Unheard of.  Definitely something to consider.
