I don't see a thread like this and decided to start one. Got my Parasound A21 a little more than 2 weeks now. Using it to drive my Paradigm Signature S2 mains (as part of 5.1 playback system), I am very happy with the results. I listened to Two Men with the Blues this morning and this is the first time ever I don't have listener's fatigue after playing multiple songs loud. I believe the main reasons of the improvement is due to the initial 10 watts of class A power. Owners of Paramount amps, do share your thoughts here. Thanks!
