Reasonable integrated amp for Magico A3

Depends on what sound characteristics you’re looking for.  You should start a new thread BTW. 

The A3s are not as bright as other Magicos but they like power like other Magicos.

It is possible, even likely, that you will find the Nova too bright and lacking in power/control over bass.  

At the NY Audioshow in 2018, the A3s were launched using AVM gear.  I would look seriously at AVM as tonally it is in the goldilocks zone for these speakers.  Read the reviews of that room and the comments are you basically only heard the music and forgot about the equipment.  

For an integrated, the A5.2 or A6.2ME would be brilliant options.  The 5.2 comes with a DAC option which is very good for the money but externals are better.  Read the review in Positive Feedback by Gary Beard.  The A6.2ME is much better.  See very recent review in Stereophile by Herb Reichert.  These are high power amps that will handle the A3s with ease.  

Both are best with a neutral to forward DAC.  Something like an Audiobyte, Rockna Wavedream (Wavelight is too warm) or Chord TT2 would be a brilliant match with these.  If you go with or have a DAC that is too warm, you will have an issue.  

I am debating between buying a Magico A3 vs Yamaha NS 5000. 
Wondering what amplifier will go with each.
Was considering Devialet expert pro 220, Hegel 390 and Hegel 590 and also Macintosh ma352 with a separate dac&streamer. 
Re thinking if Hegel h590 will be tooooo much power for either one of these speakers which are rated as:-Yamaha NS 5000 - 200 watts at 6 ohms-Magico A3 I think 300 watts at 4 ohms

Re thinking also if the devialet expert pro (220 watts at 6 ohms) is enough for either of these speakers. 
Really confused bcos trying out the different mix and listening to how each sound is not possible due to corona lockdown.
If anyone has any ideas  wud be great.🙏🙏🙏

I listened to the A3’s with Hegel gear at Overture audio in Wilmington De and they sounded very good. Also with Naim and Mac separates and all sounded really good. Only integrated was the Hegel and very nice presentation and good control

I’ve heard Alon Wolf really likes Hegel amps and that they are one of the amps he uses to voice his speakers, so maybe an H300 or H360 would be worth adding to the list.  At this level it’s all about sonic preferences, so maybe calling Magico and sharing your tastes with them would yield some good recommendations.  Hope this helps.  Congrats on your new speakers, and best of luck. 

ML 585 used will set you back 6-7k and you’ll be set. Has high quality dac built in. Glowing reviews and you’ll be shocked that you can purchase this level of integrated amp for this price. It’s a beauty. FWIW

Check out Aesthetix MIMAS great integrated hybrid $7000 you can add DAC and Phono 

I like Jadis tubes with Magico. I’m running Jadis I50 with S1
