153 WESTERN ELECTRIC TRANSFORMER ④ performance test with : David Fray ♪ Bach Concerto for 3 Pianos

Performance test shot on ipohne8 attaching with stereo mic ( iQ7 : 120 Degree )
First of all, I apologize for allowing noise to be mixed in the video. The cause of this noise is the microphonic noise generated from the vacuum tube. This is an event that occurs because the warming up of the tube amp used was not enough at this time. Thank you for your patience and understanding.

＊ What is “magic force” in audio products of the 1930s Western Electric Golden Age?
The sound of mysterious beauty is what is called "Western Sound".
A strong impression that time and space spread endlessly,
and a microcosm that sparks a metamorphosis appears.
The supreme wisdom and smartness of modern science
seem to bring back the ancient lost shamanic magic.
I call this effect “Elan Vital".
