Class-T amplifier for Harbeths?
By coincidence I have just returned from the home of a BBC sound engineer to whom I was giving the UK-first demo of the Monitor 40.1.
After the main demo his friend arrived with a home-made stereo 2 x 20W Tripath Class-T amp in a small box powered from an internal 12V battery charged from an wall-PSU type external mains supply. I have no direct experience of 'digital amps' (although I'm told that Class T is not actually digital but Pulse Width Modulation) and was very curious.
I was astonished how good it was: warmer and sweeter than the main amplifier. I was doubly astonished that such a low power amp could drive the M40.1 adequately loud and to such an excellent standard. I've borrowed the amp and ordered from him the 2x100W big brother.
I'm so impressed with this miracle amp and its sweet sound - which would certainly drive C7ES3, M30 and probably M20 that I wonder if there is a small market for it at a sensible price? I am not saying that it would compete with big 'audiophile' amps or have a long life expectancy - I am saying it opens up many possibilities and is definitely a small investment worth considering.
