Apparently, a lot of classical music studios really
are using B&W 800 series speakers as monitors, so it does make sense that those would recordings would sound better on those speakers. Circle of confusion in action.
It's really time we retired the "circle of confusion" notion. It's decades out of date, and full of misconceptions now. In the real world, no mixing engineer sits back at the end of the day and says, "This mix sounds great on the B&Ws this studio installed, so my work here is done."
Instead, the final result almost certainly
won't sound great on the B&Ws, or the Neumanns, or the Genelecs, or the ATCs, or the JBLs, or whatever, but the engineer sits back and says, "My
professional educated guess, upon which my reputation and future employment depends, is that overall, this mix will sound good on cheap earbuds, decent IEMs, fashion headphones worn over a beanie, decent headphones, in the car, on the homepod speakers on the kitchen counter, the soundbar under the TV, the cheap stereo, the decent stereo, the audiophile rig, and the speakers in the grocery store ceiling."
Thus there cannot be a "circle", because the end-point is totally undefined now. At best, the chances of a track being consumed on the same speakers it was created on would be a million-to-one coincidence.
All that an engineer needs from a monitor is his own notion of extreme clarity, and that can be found through several different options. The 8361 is an excellent choice (I own 20 of them) but there are others equally serviceable, some of them preferable to different people for different jobs.
All that said, I realize that having been a recording/mixing/mastering engineer makes me, per ASR orthodoxy, a deaf moron, so feel free to ignore.
