Having designed and built some of my own gear over the past few years, I can honestly say that (to my ears) new gear doesnt sound half as good as some of the old stuff. Everyone seemed to hit a good point that vintage + aged components add character to a unit (mostly by adding distortion from dried out caps, etc..)
With that being said, these new designs are "technically" far superior on any graph or chart that can measure THD, SNR, bandwidth, etc... BUT dont forget that by doing so, you're eliminating all of the "character" and "vibe"
I've used an SSL G for 10+ years. The first time I sat behind an SSL J, I thought it was broken. I couldnt figure out which button to hit to make all the good stuff come back to life.
ok but at what point does it become subjective to taste??? if you had worked on a SSL J or duality or aws 900+ and made hit records that everyone raves about the "sound and vibe" and then worked on an SSL G wouldn't it work the same way???
if andy wallace mixed a whole record using a brand new ssl board and a reissued la610 for vocals, it wouldn't sound good and have its own character???
