I'm sure you understood JA measured words and understand enuff yourself to see the fly in the ointment test results ...
This amp will have issues driving real world loads and is truly only an 8 ohm load amp , secondly it's distortion knee is pretty sharp , so there is no gradual rise in harmonic distortion which is necessary for audiophilia warmth and since JA did not do a low mW test without the noise for us to see what the first what looks like i csnt comment there ..
IMO If you place this Halcro amp on a 4 ohm nom speaker, with Z-Min in the 1- 2 ohm range you will find the drive disappointing , also with such low thd/imd levels the pre amp will provide the sonic charateristics of the Halcro , pre-amp and cables will be ultra sensitive here ..
