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 listened to the A3 a few months ago while auditioning speakers. At the time I took my ARC Ref110 with KT120 so I could have a fair comparison what each speaker sounded like with my own amp.  The A3 did not sound that good with the ARC.  The dealers also agreed and said the A3 like higher powered solid state.

That's a great tip !! Think Iv'e decided which amplifier to buy and i think ill do it this month, if someone won't change my mind here at this forum :).  I probably will go on CAT JL7/CAT JL7SE
Thanks a lot!
All I can say the bass was bloated or muddy. Just didn't sound controlled and tight. The A3 needs juice.  As another post above a Pass X250.8 would be a great amp to try.  If you don't like it they don't last long for sale. 
From all I’ve read over a period of time the CAT JL5/JL7 power amplifiers have more stout/robust power supplies higher reserves and energy storage thus higher current capability compared to ARC . This according to posters on the whatsbestforum.com forum who’ve compared these two brands. I’ve heard both but not in direct A/B listening.
