A review of the heresy III's from a reviewer that I have bought products on his recommendation/s with no ill affects. Basically I have trusted him since the 90's.I own a pair of H-IIIs (and four pairs of pricier speakers) and I mostly agree with his assessments.

For low-volume, late-night listening, the H-IIIs with a 20 watt tube amp are hard to beat.
Any speaker at the $2K price point has strengths and considerable weaknesses. What the H-IIIs lack in bass extension they more than make up for with bass speed and definition. What they lack in refinement they make up for with a lively and dynamic sound.
