Hey,
Anyone remember "Quad" sound from the 70's? They had to come out with super high freq. cartridges to pick up the rear channel data which was encoded in ultrahigh (beyond hearing) freqs. At least in one scheme. Response specs without dB's to tell you the max. variations can be misleading or useless. I guess it is nice to go up to 50k, like on my Grado, it may hint at some refinement, but what exactly it proves is a mystery to me. But analog master tapes can go higher in freq. response than CD's so maybe that is a good reason to go beyond 20k, whatever harmonics are there, maybe it will delight housepets. Maybe transient response is enhanced by HF extension beyond 20k in a ctg?
