Revel paid a visit to our headquarters prior to the launch of their Performa M126Be bookshelf speakers. Luckily for me, they had arranged an extended listening session for us.

I found that the M126Be created detailed, neutral, and non-fatiguing sound — even at extended high listening levels. One of the most impressive attributes of the M126Be is its off-axis listening. The beryllium tweeter uses an acoustic lens waveguide, which helps it produce remarkably accurate sound, even if you're sitting off to...
