Not the case in my studio, where almost every famous piece of equipment is racked. Without shame, along with some Behringer gear as well, when it proved my ears to be helpful.

I could've ordered a 6176 without thinking, but I wanted to give the 676 a try. In my experience, talent is way more important for the end result, than the last 5 or 10% goodness difference between 2 pieces of gear. Some gear is exceptional though. For example I found no replacement that did the trick as immediately obvious and convincing as an original CL1B on vocals.

Esoteric discussions about differences between EQ on vocals are kind of amusing, when you have working experience with really gifted ones. I think the lucky among you, will exactly know the phenomenon where you hear, that such a vocal hears the sound and instantly adapts in an EQ-like way. Is it missing a dB in the highs? They -will- sing a bit brighter without thinking and asking.. In a second they render so many discussions obsolete.

It is all about adapting. We all know the comments to YT videos of very talented guitar players where people react and write:
"You can make a cigar-case with a string shine and sing..."

Exactly. While they and their skilled hands are able to adapt to the Squier or the Epiphone and blend out -breath taking easily- the 10% difference to the A-brand.

It is poorness which dictates to -not- work with gear from brands which prove your ears, to do the trick. In my space everything and everyone is invited which/who proves to be an authentic servant to moving music.
