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.

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 speaker with an upfront sound.
I previously had NAD C325 BEE.
Average to good but far from my expectations.
Like someone pointed in another forum,RS6 tend to have a bloated (uncontrolled) bass when used with not enough powerful amps despite its relative high sensitivity.
I suspect that a good tube amp would mate very well with these speakers but I don`t like the idea of having a high level of dissipated heat and all the required burn-in time before audition.
Naim is very appreciated on all forums and I think that in the end will be my final choice.
Before you pick the naim, I think that you should try to demo it if you can. You mention that both amps are noted for being bright. You can argue that the naim may be bright and forward. I thought it sounded ok on naim speakers and a pair of BW lm1's on my computer. But when you put it on a better speaker like the one that have, it falls apart. I thought it did not have a clean sound. It is hard to explain, that's why I say listen to it first. The creek is just the opposite. It is more powerful and just as lively as the naim. The top end, though, is in a different league altogether. The reason that I went into the passive pre amp section in my first post was to stress this point. In my opinion, a good active line stage will cost a lot more than the type of components we are talking about here. I this case, the passive pre will work greatly in your advantage in that you are eliminating a large bottleneck in sound quality that an active line stage will create at this price point. The reason that I would not chose a tube amp in this setup is that your speakers, with a good british amp, will give you that propulsive sound that the british electronics are noted for. (although I am sure that tubes will be ok as will; just not my first choice. Hope that helps.
Thanks for the detailed explanation.
What interconnects would you recommend if I pair Naim to RS6?
Previously,with NAD C325,I used Supra EFF-ISL,Atlas Equator mkIII and Chord Crimson.
The best result was obtained with Supra cable which seemed more detailed and musical than the other ones.
