You're looking at, among other things, a Western Electric 11A horn system c.1924 (before the advent of electrical recording) courtesy of the fine folks at Silbatone Acoustics
. Silbatone's own electronics designed by J.C. Morrison provided the juice (using vintage, and I mean vintage VT-1 and VT-2 triodes), while one of Frank Schroeder's or Thomas Schick's tonearms rode the grooves. All-in-all, this was the most goosebumps inducing sound at The Show, at least according my goosebumps-O-meter, as it was able to convey the life
in music. I find some systems, OK some modern systems, pale in comparison on this note, delivering a strained sounding imitation more intent on sound effects than music or in the worse case serving up music that is, for all intents and purposes, DOA. A corpse.
