Dick Olsher of The Absolute Sound concludes in his January 2016 review, "The L3A distills the best attributes of modern tube sound: swift transients, a detailed presentation, and natural yet non-euphonic textures. It is its insistance on the sonic truth that defines it as a true reference line preamp. The L3A's ability to retrieve the music's rythmic drive and drama make it one of the most sonically persuasive line preamps on the market and one of the best I've auditioned over the years at any price."

The Audible Illusions Modulus 3A, introduced in 1996, was just named one of the 12 (#8) most significant Preamps of all time by The Absolute Sound. "The M3A delivered reference-caliber sound quality at an affordable price...it excelled in transient quality and soundstage transparency; its textural liquidity was also a most satisfying testimonial to a classic tube heritage." Fast forward 16 years to the new and even better M3B. If you love vinyl you won't find a better preamp at or near this price.
