Product Description

When NAD's Masters Series M15 surround sound preamplifier was introduced in 2005, it redefined the performance and value expectations. With a string of rave reviews and awards including the prestigious EISA Award for 'Best Home Cinema', the M15 has become a classic in its own right. There is now a new generation of video source and display products that support high-resolution video and high definition audio. The new M15 HD has been re-engineered to take full advantage of these new High Definition formats.

There is also a requirement to 'redirect' bass frequencies, depending on the capabilities of the particular speakers used in your system. All this processing is controlled in the M15 HD by the latest high speed DSPs, loaded with NAD's proprietary software. These DSPs are capable of hundreds of millions of operations per second! All of this processing power keeps the everyd
