To go a bit further.
I did feel a bit burned with the noise issue on the amp, Rogue suggested it was a product of implementing valves and class D, unfortunately my dealer had a no return policy after home demonstrations, I did not notice it until the unit was purchased (I did not at that point check amps for noise on demo) I probably could have got a refund/exchange had I argued the noise issue but stayed with it as in practice during use it was not noticeable when sitting away from the speakers.
I accepted that amps will make some noise, until checking out the aforementioned NAD, it was easily the quietest amp i've (not) heard. My old naim nait 3 by comparison gives a slight audible hiss.
Hopefully sphinx V2 has fixed the hum/buzz and it is perhaps telling that V2 comes so very quickly after the release of the original model. I'm surprised such an obvious flew was not picked up prior to release of the original. It is disappointing as had the sphinx been quiet I would no doubt still own it.
