Today I got one of Duncan's (Tubehunter) class D amps which he was flogging the other day. Amp based on modules from Sure Electronics.

Switched out my Radford STA25 and inserted the Class D Amp - and Wow! Amazing ...

Had a few hours of settling in and these are singing very sweetly. Wide open, fast and just 'grips' the music. Very precise sound with nice balance across the dynamic range. An easy non fatiguing listen, especially once warmed up. I rather expect that over the next days they will settle in more.

Honestly I'm shocked how musical this amp is, not as sweet/warm perhaps as my Radford STA25, but still very engaging with lots of depth and 'presentation' - really quite the opposite of what one generally expects of a Class D amp - normally expected to be thin sounding and whatnot.

Just saying ...
