Help - Opinions - Amp for Sonas Faber Olympica III Speakers

I owned the Parasound JC5 . I was powering Kef R900s 

Preamp T1 tube with nos tubes . The JC5 was superior to A21 , Pass 150,Premaluna 300hp, Mcintosh 302. Then I had purchased a Coda continuum TS to compare against the JC5 . The outcome of the comparison between the two was that the Coda continuum TS was a far better controlled and musical presentation in all areas. Ten year warranty. If you call the company you will likely speak to the owner and designer directly. 

I'm having very good results with ARC REF75SE.  Had 2 McIntosh solid state amps,  Pass Labs X150.8 and the REF75SE sounds the best.  

The ARC REF75SE sounds like an awesome choice.  I’d also look at the newer GaN amps from Atma-Sphere and AGD.  Or, buy a used McCormack DNA-1 and have SMcAudio do their full mods on it.  All are awesome options.  

The proverbial quest for nirvana. My opinion is you get bored with your system.

Waiting for a NAD M12 to ship.

After lots of looking at amps I decided to go this route. The only amp I wanted was a Coda Continuum No 8 with meters. 

I figured the pre amp was the weak link in my system and this was less money.
