During the four years that I've reviewed for Stereophile, I've had the privilege of evaluating products from some of the world's best-known audiophile companies: Audio Research, Bel Canto, CH Precision, dCS, D'Agostino, Dynaudio, EMM Labs, Jadis, Krell, Nordost, and Wilson, among others. But one long-standing manufacturer whose exhibits at audio shows invariably inspire ecstatic reports, Germany's MBL, has remained outside my purview.

I've been wrestling with my elders about new ways to measure loudspeakers, lobbying for methods that might correlate more directly with a listener's experience. And wouldn't you know? Right in the middle of this Socratic dialogue, I put the fresh-from-UPS, $1000/pair, Tannoy Revolution XT 6s into my reference system, plunking them down on my 24" Sound Anchor Reference stands in the same spot my Harbeth P3ESRs had been sitting. And I freaked! I was using the Rogue RP-7 preamp and the Rogue Stereo 100 (100Wpc) amplifier, and I could never adequately describe how bad the shiny white Tannoys sounded. Imagine sound that's thin, metallic, herky-jerky, dull, and rolled off completely below about 90Hz.
