Digital Amp Comparison 2006

This little get together actually compared the latest digital, semi-digital, class D, class T, switching amps and the like. The aim is to help promote the use of these new amps, the companies, and to give some feedback as to how they compare. This technology may well represent the future of all entree level, mid-fi level, two channel, and home theater amplification. Some may even over take some of the big names in the high end market.

Special thanks to all the companies that sent amps. Without them none of this would have been possible.
