They old ones sound amazing to me just racked up - the new ones are unbalanced so you just put the 2 cables to ground.
I just sold a rack made by Helios in the 70's for outside the console - i have two more for keeps.

The Neve's sound different racked up - sometimes better, depending on what
your looking for while tracking.
