I read the measurements and they are quite respectable and aren't pejorative in substance or assessment. I'm not sure of the point of this post, other than an axe to grind with the concept of Pass? These amps are massive, heavy, and there are two of them. Adjusted for inflation, the XA100.8 pair would have been about 6.5K in the mid 80s, back when a Levinson 200W, unbalanced, stereo ML-3 was 5K. A pair of ML-9 amps was 6K which would be about 18-20K today.
Want to spend less? Choose the X60.8. I have a pair of XA100.8 which replaced the XA60.5 which replaced Classe MA-600 and Luxman M800a, which replaced a pair of Bi-Amped Accuphase A50s, all of which were excellent.
