One of the most distinguished reviewers in the U.K. press, Mr Paul Messenger had some very complimentary things to say about the LS-77s: “Both the bass and treble extremes work very well, but the midband is the most important bit. Here the LS-77 demonstrates seamless transition from one driver to the other, exceptional overall coherence, and very superior stereo imaging, so much so that the steep slope filters used in the crossover seem to be entirely positive, while their inevitable complexity didn’t seem to be any impediment to the sound quality.”….”Though certainly costly, it’s also quite discreet and very elegant.
Good set-up flexibility and a fine ability to distinguish between the various components and accessories with which it is used suggests its Reference Class Professional Monitor tag is entirely appropriate.” We would like to formally thank Mr Messenger and HiFi+ for such an insightful and wonderful audition of the LS-77.
