"The sound quality of this audio DVD is simply superb, with an immediacy and presence that gives one the illusion of a live performance. The soundfield is both wide and deep, all around you - using Tacet"s "Real Surround Sound" which places the listener in the midst of the quartet. Each of the four instruments is in its own definite aural space while allowing each one to bloom. Tacet specializes in this form of surround sound and the results are excellent." (Audiophile Audition)
