These were/are well-respected amps and received good reviews as I remember. I'd also like to see inside... anybody got the schematics??

I have a DNM preamp, early model in metal case. It seems to be a budget model, as many components are "missing" on the boards, mainly the complementary output stage. I did some reverse engineering, too and could do a hand drawing of the schematic.

Soundwise, it is definitely better than a Naim 82 with Hicap.

BTW, if someone would send me a DNM power amp, I could do reverse engineering for that, too.

kind regards,

long time ago, but I had one, drew it out, it flummoxed me a bit, quite simple as I recall.

single diffreential pair with a current source tail, single transistor, can't recall bias.

loaded with current mirror.

can't recall VAS, quite simple, similar to naim one, perhaps a darlington,

and I thinnk into 2 mosfets, power, simple as that, total transistors I recall to be around 11.
