Some time after my review
of the self-powered Paradigm Shift A2 speakers ($279/each Ash Black Grain, $329/each Premium Finishes), Paradigm
decided to re-think their design primarily to deal with the tweeter noise that I and others mentioned. Well here's the new and according to Paradigm improved Shift A2! In addition to adding some user-friendly features such as a soft mute after 30 seconds without a signal passing through and a full mute after 30 minutes of silence, the tweeter level was knocked down by 8dB.
Fortunately for Paradigm their room at CES was packed with people (I felt like I was at a party) so I did not have an opportunity to hear how much quieter they are. A follow-up review is in the works and I'm very much looking forward to the Shift A2's quieter return.
