I'm still a purist when it comes to the different classes of amplifiers specially when you design amplifiers from tubes, darlington transistor and mosfet using manufacturer handbook. I still prefer Class A and A/B amplifier stages it has better sound when you have the proper speaker gear to match.
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?
