NAD C658 Network Streamer Pre-Amplifier

$3,499.00

Free Delivery in NZ
for orders over $100 or $5 under $100.

Product Description

The C658 is an entirely new type of component that combines a network streamer, a state-of-the-art DAC and many aspects of the traditional pre-amplifier in a single highly cost effective package. The two MDC slots present on the C658 allow for expansion to accommodate 4K video pass through. Dirac Live Room Correction helps to combat the short comings on the room your system is in, getting the best possible sound in any situation.
