My Benchmark AHB2 does a pretty good job but I don’t get drawn into lengthy listening sessions with it as much as I do with my SET amp. Benchmark seem to be one of the companies leading Class D technology in the US so check them out if you are considering Class D. This amp can either be used in stereo mode or you can use two in mono mode if more power is required
Class D amps that are superior to all or most?
Recently, I have heard about some Class D amps that may be close to the best there is regardless of class. Certainly, this technology has been in development for decades. The main issue has always been the switching power supply. In this regard, I have taken notice of AGD. They have created a whole new power supply that “switches” at a frequency 100 times the normal silicon based MOSFET. The designer uses a gallium nitride based PS. Interesting, it is enclosed in the KT88 glass envelope that sits on top of his amps. I am aware of two more pricey amps that seem to be also at the top- the Solution and the Merrill. There must be others that compete for the title. After my thread, “Is there a SS amp that can satisfy a SET guy?”, I am still on the quest.
