Aron Garrecht has posted a review of the Classe Audio Sigma Amp5 multichannel amplifier ($5000) at SoundStage! Access. His conclusions:
“Listening to Classé’s Sigma Amp5 over the past few months has reaffirmed my opinion that digital amplifiers need not sound “digital,” and that the future of digital amplification is secure. For use as a home-theater amplifier, the Amp5 acquitted itself without flaw, and, perhaps more important, instilled a sense of quality.”
