In my experience I agree that the 'best' sound tends to come when preamp volume control is 10.30 to 12.00 o'clock best balance between openness, power, dynamics and clarity. This has been subjective on 4 amps over the years and whilst not fully sure on the science suspect may be related to minimising possible preamp overload in some cases and allowing the power amp to function properly I am sure the more educated may be able to clarify.


Another Neh. They make them do nearly full output at around 1 o'clock to sound impressive! Been there - didn't like it - resigned.

Hi, pictures in new website great and notice the Proprius has a different power supply to the normal psu. Is it a different case or differing supply?

Yes, it's a 48 volt bought-in switched-mode with built-in short circuit protection and excellent regulation. Does 120 (real) watts.

These little gems need no tweaking whatsoever.  

They are driving my 6Ohm Harbeths with ease and then some srtrapped to the back with super sticky velcro.  It's just amazing how quality sound travels at normal listening levels.  

It's fair to say everything else sounds poor to middling by comparison.
