Pitting Class-D against Class-A is not even a fair argument. When 95% of all mid-high end amps out in the world are Class-AB.... isn't that where the comparison should be? I have zero interest in owning a VERY inefficient and costly Class-A or Tube amp, and have owned many great class AB amps in my lifetime. I've heard $2000 amps that sound amazing, and ones that sound lifeless and boring. Switching amps are finally up to that level of quality.... matching amps in the $2-3k range, but maybe not beating out $8k amps. It's an interesting time in Audio!!
High End Amp Price Collapse musings
If Class D amplification becomes accepted by audiophiles there should be a glut of high end amps (Krell, Levinson, Pass etc) becoming available on the used market at prices a fraction of what they are now.
Think CRT TV when the flat panels began emerging.I think Ill hold off on a new/used amp purchase for a little while. Maybe I will bet a Boulder.
Has any one else considered this?
