Simaudio Moon 600i v2 VS Naim Supernait 3 for Dyanudio C20s


Hello Everyone,
I have narrowed it down to two int amps for my contour 20 speakers. My current room is 15 x 20ish and I am trying to decide between simaudio moon 600i v2 or the supernait 3. I have listened to them at different times in different stores but with the same speakers so I cant directly compare. I am looking for blacker backgrounds, better separation good bass control and of course good vocals etc.. I have bluesound node 2i connected to an external dac. I am strictly intersted in these 2 int amps. I know Simaudio is almost twice as expensive (if both units are bought brand new) but either could be had as used for a lot cheaper than their MSRP.
Any recommendations and experiences would be highly recommended. Again I am only intersted in simaudio 600i v2 or the supernait 3.

Thank you thank you!!!

So you’ve used the services of a couple of dealers to hear the amps but still can’t make up your mind and have no intention of buying from either whichever you decide?
@yeti42 - Different music played in different rooms with different room treatments so it is difficult to compare side by side.(if you reread my statement above). Both sounded great!
What I want to know if power is going to be an issue with supernait 3 when it comes to control and dynamics at mid to higher volumes as dyns are 86db sensitive?
Both sound great but I just wanna be sure before i buy either because I am going to be keeping it for a long long time. 
How comes you didn't answer this basic question from your own demos?

You've auditioned two amps; one amp twice the cost of the other, and liked them both, and remain interested only in deciding between these two products. This thread is strange.
