On the same subject, how would you CLR users compare them to a studio reference monitor? Which is more accurate? Obviously, monitors can't be a stage solution because they can't compete with other instruments, but for home use and tweaking profiles?
Mhhh... I find he question being slightly misleading; it assumes all the reference monitors sound the same. It would be like asking "how do FRFR cabs sound".
Any serious comparison has to be made between specific models IMO. Ingolf's answer is quite proper in thos respect
I'd also note that a profile is too simple a sound for a proper "by ear" comparison or even evaluation. A full music program (best if a live recording of acoustic instruments with few mics) would make for a much better test, specially if you're already well familiar with the program through other loudspeakers.
