If you’re going on measurements, sure.
It’s a case of “live by the sword, die by the sword”. The focus by Benchmark is about its measurements, which are almost matched by an amp using similar technology for $400 instead of >$3,000, and which the deltas between are well below the most generously considered audible thresholds.
But everything in audio, or at least everything that’s competent, is subject to the ravages of “the law of diminishing returns”.
The THX AAA 789 measures better than the Phonitor X too. But having done blind listening tests with them (and the HPA4) there’s no question which I’d rather listen with.
Beyond that …
There isn’t a Phonitor X in the preview program at the moment. I can’t see adding one until there’s a reasonable number of people that are at Tier 1 either. And even then it’s dependent on a number of other factors … though that’s really @taronlissimore’s call.
If you wanted to compare software that provides the same sort of cross-feed/speaker simulation that the Phonitor line has, that’d be interesting. Though comparing it TO the Phonitor X is going to be an issue per the above. But most of the interesting software of this nature is available on free-trial. “Waves Nx” (on sale for 50% off at the moment), with the head-tracker, is probably my favorite (and the most convincing) implementation I’ve heard.
And you can just post impressions (it does not need to be a full-blown review, just enough to help others understand the nature and sound of the thing) of something you already own to get started. It is more about showing willingness and ability to do so than it being about something new or that hasn’t been written about before.
It’s not that hard, it’s not a very high bar, you can do it with gear you already have and my repeated experience (from other forums) is that people that won’t take that initial step generally don’t wind up posting impressions about loaner gear either.
