Please note that this document contains the text from the original product brochure, and some technical statements may now be out of date
Designed and assembled to professional recording studio standards, the 208 delivers unsurpassed levels
of high power combined with an enviable audiophile performance. Every aspect of the 208’s
components, circuitry and features have been developed absolutely without compromise so that a much
impressed reviewer in the respected Swedish audio journal New Music and Sound Technology wrote in
June 1994, “This is the best power amplifier I have experienced ever”.
The specification which earned this and other similar accolades is awesome. First grade components are
employed throughout, including precision metal film resistors, high quality capacitors and a truly massive
toroidal transformer which assures a noise free open sound stage and totally transparent audio quality.
The MOSFET output stage delivers power plus signal speed and control, driving any loudspeaker load,
even below I ohm. Switchable balanced and unbalanced connections are provided with a choice of
professional XLR or phono sockets for more flexible use.
Although the NAD principles of uncluttered design are incorporated into the 208, Soft Clipping and
Extended Dynamic Power circuits are included, which both protect the amplifier from over enthusiastic
use of the volume control and add to the musicality without any loss of dynamics or dramatic
performance.
Absolutely every relevant design detail has been considered, down to gold plating on the connectors
and heavy duty binding post speaker terminals. The nominal 250 watts per channel will extend to 600
watts peak entirely without a sense of strain or effort.
Bridged for mono, a pair of 208’ s (a combination which won Five Star approval by What Hi Fi? in
1993), can provide up to 1800 watts peak, academic figures which nevertheless guarantee serious audio
quality across the entire sound spectrum.
