Is Class D Analog or Digital ?

Wow!!!..what a conversation! I called Music Matters yesterday in San Francisco inquiring about an older Spectral 
Preamp since their an authorized dealer for many years. The salesman I spoke to was not familiar with the DMC-10. He took my phone number and said I'll have someone get back to. I received a phone call today from the co-founder/owner Jay. I asked about the DMC-10.He trashed the piece saying it is grainy, bright and the newer designs are the opposite.
Nothing could be further from the truth. Us Spectral geeks know exactly how those older models sound. I told him I already had made a decision on amps. He asked, which amps are you getting? I said the Nuprime Evolution Ones since
Demiam Martin from Spectral is co-designer. He said don't buy them... their digital amplifiers and I tell my customer's to stay away from them because of that bright digital sound. Wow! I said they are analog amps and Class D is just a category. He said no, the D stands for digital. This is another prime example why so many Audiophiles are skeptical and will not put their toe in the water to go the class D direction.

binary and dual switching have nothing to do with each other.

"it is binary, not digital, and it is quite confusing"    no such thing as a binary mosfet transistor. binary is only a digital term, for the 1+0 reading from the CD or other formats where 1+0 applies.

Erik....you are confusing an analog Class D amplifier with a CD player. Binary is a single term/method only of how a laser reads the pits on a compact disc. The space in between the pits are "bumps" results in reading pits,bump,pits,bump, 1,0,1,0,1,0.....switching only applies to switching transistors. Mosfet's are dual switching, moving current in both directions. Diode transistors move current in one direction. Just about all Class A/AB amps use switching transistors. Binary only applies to the digital domain and nowhere else. Nothing confusing about that.
