NAD M27 or Parasound A31, which will sound better?

I would like to replace my Home Theater amplifier around Xmas time and I'm considering these two amps. Budget is $3500 at max.This will be replacing my 20 year Yamaha DSP A1 which I still think to this date, sounds very good.
Currently, I only have 3 front speakers L,C,R. Martin logan Motion 40, and Motion 30 center @ 4 ohms each. I will though, add later on ceiling surrounds, but not anytime soon. So I only need a 3 channel amplifier for now. I have 3 active (250w) subs. One 10" and two 2 dual 6 1/2" that will handle the lower frequencies. This new amp will be paired with NAD M17v2 Pre/Pro. That's one reason for my interest in the matching M27. It also has 7 channels for when I add the surrounds later on. The Parasound A31 has only 3 channels, but I like the looks and I wouldn't mind getting a 5 channel amp for the surrounds later. The A31 has more power (250w), VS (180w) for the M27.
This will be use 50/50 (music/movies). I mostly stream from Amazon Music now HD and Prime Video, but also use a 4k player to watch movies. 
I have not listened to these amps, nor have I ever owned the same brand. So I don't know what they sound like. Ex. Warm, neutral or bright. Parasound is class A/AB against M27 class D new Hypex nCore amplification. 
Comments and suggestions are greatly appreciated. I will like opinions on these amps or any other 3 channel amplifier. I prefer 3 channels for the fronts. There are many options for 2 channel amps. But I do not like to listen in stereo anymore. I Prefer multi channels or Enhanced Stereo. Could consider hybrid tube 3 channel if there are any.

Thanks!

Between only those 2, I would go pick parasound for reliability.

 For the price point you mentioned, there’s a LOT of wicked amps u can choose from, keep watching 

 3500 u said?
 You have a huge selection of amps, integrated, Hell, for 3500, you can get a killer amp AND preamp.

Happy hunting

Edit:

I've owned the NAD, and though I think the NAD is a good buy at that price point, with the speakers you have you could use more current delivery than the NAD provides at 4 ohms and below.

Since the OP, I have bought myself a used Krell Showcase 7 amplifier, but have not been able to try in the system because is in the process of getting serviced. (All new Audio Note caps on all channels and power supply.) meanwhile I've looked at the Emotiva XPA-DR3 and wondered how it would compare to the Krell Showcase after getting re-done. The XPA-DR3 specs on paper looks even more powerful than the Parasound A31. I've only own one amplifier all these years, and that's the Yamaha DSP-A1 and while it still provides decent sound, I would like more power for movies and a cleaner more detailed sound for music. Comments and helpful advice are appreciated.
