Who has heard Accuphase C2400 and C2800?

They are electronically the same.
The C-2800 is just a more luxurious execution. But they both sound great, the same.

PS I must add the the C-2000 is already excellent !
Quite as good as the C-2400 and the C-2800.
The real difference relies in the optional cards, extensions : mainly for phono, turntables.

You can add a better Accuphase card (more expensive, of course) as option on the C-2400 and C-2800.

Having a Lamm LP-2 for phono, I didn't mind that and bought the C-2000, a great preamp.

For what it's worth, this is from Echo Loft. BTW, I got the Marantz SC-7S1 preamp and love it:
