There are all kinds of problems with this "review." Among them: The unit was acquired used, so there’s no assurance that it was functioning properly and - more important - PS Audio wasn’t given an opportunity to respond. So it’s just a hatchet job. Typical ASR. Nothing to see here. (Unless of course, ASR wants to accept the standing offer from @ted_denney . Then maybe we can discuss ASR’s credibility.)
There are many other issues with this "review," which itself is just a measurementalist’s fantasy.
