Thanks for the link, Cno. It is a very good write-up and even allowing for the odd translational quirk it is compelling and in a style not so often seen in the UK.
I was amused at one comment in view of a recent thread here:- "Even height perspective is clear on the right recordings."
On a detail point, the terminal block seems a good idea with its bi-wiring option and link replacement.
Interesting perspective on advances in speaker design in computer age and with Chinese assembly - very plausible but equally so many older designs still sound good so I am unsure what he 'real truth' is here.
