When NAD had a good design team.

The 2600 is a Monitor Series power-amplifier with a "lab" input (to be fed from the preamp out and bypass input controls), 1x 1,6kW (at best) of peak output available maintained in listenable regions with NAD's staple Soft-Clipping circuit.

That much output goes with the Power Envelope circuit : two voltage rails for high and low power ranges. When listening loud, switching back and forth between rails therefore happens...
I believe the 2600 was also available without the PE circuit (?) and there also was a 2600A (with Power Envelope) - differences ?

Of course, to offer as much for as little as 598$ in 1987, the actual build-quality is far from luxurious or even beautiful and inside is no Bugatti : one biggamonster EI trafo, two long sharkfin heatsinks and lots of hectic cabling made in Taiwan.
But the 2600 works and was planned to do that for a long time.

And it is pretty, because, then, NAD, like Proton, really had a very good design team.


The owner's manual is still available for download at NAD's NAD's - that's for the 2600A.
