Datasat RS20i Surround Sound Processor Review

Reviewing the Datasat RS20i gave me the opportunity to evaluate a product that was designed and built for performance as the highest priority. It represents a product where the engineers apparently focused on optimum component selection and circuit design. The result is a product that tests well objectively and sounds excellent on the subjective level.

Classé Sigma SSP, Sigma Amp2 and Sigma Amp5 Review

The Sigma SSP is Classé's newest 7.1 channel surround sound processor. Classé optimized it for two-channel music playback and gave it extensive customization features. Included in this review are the Classé Sigma Amp2 two-channel amplifier and Sigma Amp5 five-channel amplifier. The combination of the Sigma SSP, Amp2 and Amp5 produces exceptional sound quality for both music and movies.
