Upgrading to a Hegel H590

I am debating between buying a magic 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.🙏🙏🙏

@puzzledconfused When I went speaker shopping 2 years ago, before COIVD, I demoed a few speakers in your range.

- my first listen was the Magico A3 when it cost under 1$0K. I liked it for the most part but I did hear the drivers a bit. I believe it was in the woofer and mid-range region.

- I then went to listen the Paradigm Persona line 3F and 5F.  I thought the top end was better on this and liked it more than the A3. Though the speaker needed warm electronics and I did not like warm gear too much (at that time). I was considering the Luxman 509x at that time but did not like it as much as other integrated that I heard later.

- I then went and heard the Vivid Kaya 90. I thought it was great but maybe too close to the KEF sound. I was planning on getting a KEF model too for another room (those plans not likely now). I liked the Kaya better than the others listed.

- Then I went and demoed the Yamaha NS5000. Unfortunately, the demo was in a bad room but I could tell the drivers on the NS5000 were better than all the others. They also had a seamless integrated sound. That is I did not hear a specific driver. The NS500 also sounded very natural and realistic to sounds I have heard live. So the Yamaha NS500 is the speaker I expect to get. 

For amplification I was considering the Hegel 390 or 590. I have heard all the models before these 2 models with KEF Blades so I have  an understanding of the Hegel sound. I think it would be very good with the NS5000.

I ended up buying a Thiel CS3.7 for my office and started buying gear with the plan on using some of this gear on the NS5000.

- the following I have or now sold would work great with the NS5000

- KRELL K-300i integrated (super smooth and amazing bass)
- CODA CSiB (great in every way but not as smooth sounding as the KRELL)
*- Benchmark HPA4 | Gustard X26 Pro DAC | Benchmark AHB2 x 2
*- CODA 07x and CODA #8

* today, I have these with the Thiel CS3.7 and 1 of these will eventually go downstairs with the NS5000. The Benchmark stack is about the price of the Hegel 590 while the CODA stack is a little more. In all cases, I plan on using the $1500 Gustard X26 Pro DAC, which I find astounding for the price.

I demoed the NS5000 with the $10K each Yamaha preamp and amp. It was pretty good though I though the $15K each Luxman preamp and amp were better (on TAD ME1 speakers).

My main concern is reviews of Harbeth talk about "warmth" and possibly less revealing.

I think some of these impressions were formed maybe 10 years ago or earlier. The new'ish Harbeth models strike an excellent balance between warmth and details/revealing. I have a SHL5+ and I can assure you it's the most balanced speaker I've ever owned. The super tweeter will give you as much detail as you like but without ever getting bright or fatiguing. If you ask me, choosing Harbeth to go with your Hegel amp is a no-brainer. You will, however, have to invest in quality stands ... they make a huge difference for Harbeths.
