Ethan, I've listened to your most excellent discourses on 'expectation bias' and how doing ones own unbiased homework is important ... to prove-disprove all the mayhem out-there. Your excellent logic has stuck with me.
I've bought your portable vocal booth ($300) which I eventually ditched ... by your own logic.
Perhaps it works for some singers, but the bulk and hazardness makes it unfeasible for serious singing.
That logic would also preclude bass traps when something simpler and easier comes along, like ARC ... not just an EQ adjuster!!!. ARC adjusts stereo for resonances and early reflections. And, TBH, IK-M is NOT a credible supplier for many Sonarites, due to its poor 64-bit support, currently.
The days of 12' ceilings and bass-traps are obsolete for me. They'd be OK for a home theater, perhaps.
I'd trust Danziland (Danny above) mastering house over Katz and Abbey Road only because the human factor rules over the psycho-acoustic factors.
Btw, Danny would probably win as the greatest artist, producer, and ME, that has ever graced the Sonar forums. Anyone care to differ?
I learned this from you, Ethan. Bit is also extremely respected here, but few of us artists and producers would justify excessive room treatments ... when avoidable ... for artistic reasons as stated.
