Summary: This review is based upon using Vantages in a two channel audio-only audiophile system for 5+ years. The associated electronics were, at various times, Audio Research SP-8 MkII or SP-10 MkII tube preamps, D70 MkII tube amp, Krell KSP-7B preamp, Krell KSA-50 amp, Ayre CD-7Evo CD player, original Infinity Modulus servo subwoofer w/cross-over, and Linn Sondek TT/Ittok/Grado Signature analog vinyl system.
Summary: From the first moment that I heard Martin Logan products in my home there was a sense of immense clarity over my previous system (a top end system from a respected vendor). One review that I had read prior to purchase stated that "Martin Logan speakers don't bring the performers into your listening room - they bring the performers and their listening room into your listening room".
Summary: My home theatre project has subtly and steadily consumed many thousand dollars of my hard earned money. Martin Logan speakers and subwoofers are expensive, but worth it. I have a 7.1 sound system setup in my home theatre room, and the sound is amazing. As I built out out my home theatre, I quickly realized that sound is more important than video. The ability to track sound of missiles and planes as the fly around you in a 7.1 movie is amazing.
Summary: I have owned many Martin Logan products, including the Vantage, and all are of the highest quality. Electrostatic speakers have a unique, open and airy sound quite different than most conventional systems, and if this suits your tastes, the MLs are among the best. Some folks find the airy openness of electrostats better for music than for home theater, but I disagree.
