Amp recommendation for RS6


Hello everybody,

I am searching currently for a new amplifier for my Monitor Audio RS6.
I have narrowed my options to the next amplifiers:
-Primare I21
-Creek EVO
-NAD C355
-Roksan Kandy mkIII
-Unison Unico
-Naim Nait 5i
but I also consider a tube amp (based on numerous suggestions that RS6 sounds best with tubes).

What do you think?
Any other options are welcome.
My source is NAD C542.

Thanks for the advices.
Again,it seems that the tastes are different in this world.
Both,Naim and Creek are known as bright,dynamic and detailed amps which seems to not complement well with RS6, an already bright and dynamic speaker.

R1g_audio,
Why would not use tubes for RS6?
I would not call Naim "bright". Dynamic, Yes. Very lively, you are there, kind of sound paired with the RS-6's. For comparision, I originally had the RS-6 paired with McIntosh amp. No excitement at all. Sounding kind of dull.
There seems to be quite a few folks using NAD C355BEE to drive the RS6. One of my friend who owns the NAD C355BEE is now looking at the RS6. Not too sure if this would be of any help. Yes, I do agree that the RS6 is quite a detailed and bright speakers with an upfront sound.
