Thanks, but far from it. A lot of stuff was never written down in the day it was just assumed that it was common knowledge, a lot of this has been lost and slowly discovered again.

There are a lot of info in there, but Bell Labs did a lot of things that were aimed at telephone use that ended up at Western Electric that was ignored in later years.

You'll need to trawl back on AOS to when Marco was re-capping his with gooey designer stuff, dedicating a whole thread to it. Loads of pics then, but I do remember it being very simple underneath and very neatly made.

That's it? That's the famous listening room :lol: I doubt one could swing a mouse in there, let alone a cat.
My walk in wardrobe is about the same size and probably has better acoustics :doh:
Also, why so many isolation stands? For one it looks ridiculous, never mind how much they cost (unless he bullied his way to a "fat" discount?).
