Haven't read it, yet, but TAS has a pretty recent, comprehensive review of this amp.

Yes, indeed! John Atkinson's measurements are always informative. However, I assume you already know that specifications and even measurements seldom tell the whole story. There's never any alternative to your own two ears. Sometimes, the sonic results defy the specifications and measurements. Some manufacturers also tend to be quite conservative with some of their advertised specifications. That being said, for the price commanded for this particular integrated, if the published THD is anywhere near accurate, that isn't particularly impressive. The published output power rating is rather stingy, as well, compared to many high-end integrateds at the same price point.
