Should I keep Naim Uniti Nova as streamer/dac or trade for a new streamer/dac


Hi guys
I had been using Naim uniti nova as all in one and they very good to excellent. No complaints what so ever. I am more addicted to class A musicality and have just purchased luxman 590axii. That is the only reason, else my nova is still excellent sounding and still love it. I only stream tidal and Qobuz with roon. I don’t use vinyl or CD. Now I am thinking whether to keep nova as streamer/dac or buy a new, possibly better streamer/dac. I was thinking Mytek Manhattan 11, lumin s1 or Aurender a10 (budget < 5k new or used: or any of above for nova trade in). Unfortunately Aurender a10 does not support roon. I am huge roon fan and have their life time subscription. Of course, I will see how nova-luxman combo sounds. Let me know what you guys think.

no worries. There is always preference in sound quality. For me, Luxman 590 was much better. 
Thanks for the response. I never said "you said" Nova sounds better. It was someone's else post. Sorry for the confusion.
I sold nova longtime back. I never mentioned nova sounded better than luxman 590. No way: luxman 590 is different level compared to nova. All I said was for the price with all features, nova sounded good. I also mentioned in that post that instead of selling them, I could have placed in my “secondary system”.

Recently, I sold luxman 590 and went for separates for my primary/ main system. I got audia flight strumento no.4 mk2 and VAC preamp. 
What did you end up with? There's a post on usmart the owner mentioned that the Nova sounds better than Luxman-590AXII for him. I thought that's odd as have read nothing but amazing on the 590.
