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 .

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.
Seriously, what you were always going to get is an exceptionally long list of member‘s own favourite amplifiers. Which may help somewhat. But in the end you are going to have to make a shortlist of suitable amps yourself and listen to them in you own home environment: there are no shortcuts.

The idea that there is one best option out there, and that you would get a consensus recommendation on this Forum is a fantasy. Moreover, you would be a fool to buy blind on the basis of a recommendation.
I saw on this site a 300B Set costing $10,000. I was disappointed that such an expensive amp uses electrolytic capacitors in the plate power supply instead of the far superior never go bad with age polypropylene capacitors instead. An SET amp is easy to design and to build. You could use 833As driven by a good 600 Ohm transformer output direct to the grids. 
I like the sound of the Audio Research gear - and in my opinion have the ability to provide rock solid bass and the ability to delivery dynamic music as good as any solid state amp including my McIntosh.

I'd also give a listen to McIntosh MC901 at that price point.  Good luck and enjoy the process and the music

I have a Cary SLP-05 Preamp with the Ultimate Upgrade and Cardis wiring. Don’t waist your time with the SLP98 when you can get one of the best sounding preamp around. It’s a two chassis rig. I use to have Cary Audio CAD805 AE. As great that amplifier is, it wasn’t enough power. Trust me on that. It is perfect for an efficiency speaker which the Magico isn’t. To calm the screaming tweeters down, you are right to go with a tube amplifier and definitely a Monoblock. Keep it close to the speakers which give you the opportunity to run a shorter length of speaker cable to the speakers. I use to have the Audio Research Reference M160 as well as the Reference 250SE. The McIntosh MC2301 was better with imaging, midrange and bottom end. Everything sounded natural with plenty of grip. This will run cooler than the Audio Research by a lot due to proper spacing of their tubes within the chassis. Trust me, you will appreciate this. The tubes will last 2 to 3 times longer than Audio Research and VTL. I hope this helps. 
Duder, you need to do the leg work this time.  If you're asking about amps   Then you made the wrong decision on the Speakers 
because you need to know how to set those babies up
  Let's get that right 
 
I've owned VTL amps for 20 years and have been very happy.  My current amps are VTL 450MKII and have never had an issue with them.  My previous VTL 300 Deluxe Mono Blocks were upgraded by VTL twice and during my visits I met with Bea Lam and Luke Manley, super nice people.
