Not true! A very misleading thread title and a false conclusion. The ML is a follow up to a full review with measurements. It addresses whether the stereo version is as good as the mono. As pointed out above, the Parasound write-up is in a section that has never provided measurements.
Stereophile, no more bench tests????!!!!
Looks like Stereophile may be cutting back on expenses, no more bench testing for measurements and specs to keep the manufacturers and reviewers honest, it'll make you think twice on what to believe now, without the proof to back it up.
