Class D is just Dandy!

He later told me in ~2006 or thereabouts that John Dunlavy used the Spectron amps to voice his SC series of Dunlavy speakers.

" I’ve set up Duntech Sovereigns, it is abundantly clear that John Dunlavy designed them to be used with the very lowest output impedance amplifiers available. They don’t even wake up when connected to even quite prodigious valve amplfiers. Even highly capable amplifiers like the ME850 barely get them under control. It takes something like the big Krell monos, or an ME1400/1500 to make them sing."

ME is what I use, in a bi-amped setup

Pretty sure the Dunlavy SC’s didn’t vary much at all from the Duntech speakers. The SC’s have a nice impedance response (6-ohms). The Spectron Musician III amp has a fairly low output impedance (< 0.1-ohms) and a high damping factor (500:1). 

Nice amps, George.

Sounds like Hypex N-Core Class-D can’t cut it with them here.

No matter how nicely you ask George to start his own nay-sayer’s thread, he’s always going to share his impressive collection of articles about how planes can’t fly.

No sir, they are too heavy and completely unreliable. Plus, you will fall off the edge of the world if you go too far.

God help those of us who want to talk about how much we like Class D, because there is George telling us we are wrong. George would skip his own chemotherapy treatment to come and tell us this.

As is the case with most of what we are taught as our understanding, we must be willing to surrender our understanding to gain insight into truth. There will always be those who refuse to surrender their understanding to learn truths. And that’s ok. We just need to acknowledge it for what it is.
