Thanks gents. It appears that not
all Sadoun S95's were created equal.
The attached spec sheet shows the model I have. It's a few years old. I guess this one doesn't support 22khz?
Much appreciate all the input and effort here.
Tks 'Sadoun'. Perhaps the Sadoun S95 spec sheet should indicate the transparency to 22kHz that the current model affords.
Looks like I'll have to upgrade.
PS Mine was made in Taiwan and not China.
