So far as I can tell, carcass93 will agree with you on macro measurements. That is, if the system has measurably boosted bass or boosted treble, he too will agree that it is either boomy or shrill.
However, when it comes to micro measurements, so far as I know, there is nothing out there that can reveal whatever it is that carcass93 hears.
Now, for all I know carcass93 may be right. There's just no way to demonstrate what it is carcass 93 (among others) claims to hear.

I recall reading in one of the cics threads as to how noise related to computer processing was measured on the output of a DAC. The spectrum of the noise was related to the buffer processing rate in the software, e.g. would change as buffer sizes were adjusted.
Not sure if this is what carcass93 was hearing, but it's a good explanation of some of the differences that I and many others have heard. It also explains why real time playback of FLAC files often sounds different from converting the FLAC files to WAV and then playing the WAV files. (Among other reasons, this avoids an extra buffering stage and the necessary processing, probably at a different cycle rate because of variable bit rate encoding used by FLAC).

The point I'm trying to make, perhaps clumsily, is that while there are measurements that everyone can agree on: frequency response, distortion, etc, there are still no measurements for the things people cannot agree on. For example, I'm unaware of any measurement that would let me tell which of two amplifiers would have a "wider and deeper soundstage," or which preamp has superior PRAT.
Audiophiles have been remarking on these details for years, yet the engineering necessary to track these details has not kept up. We're still stuck with the same tests that have been used for generations. As a result, audiophiles are forced to either grin and bear it with whatever they've brought home, or have to follow the path of laboriously auditioning components with no real clear direction of where to go.
