I haven't either, however speaking from paper too:
- why exactly are they orienting the drivers toward the ceiling; unless the tweeter is of a special design for this application, this will offer you a direct sound that is not representative of the on-axis tweeter response;
- they are also into cryogenically treated monocrystaline continous cast solid core power cables with Furutech plugs; I won't comment any more
- this pic

Nap.
