Fair comment, but what I am principally concerned with is 'normal music'
at fairly normal levels and remember I'm more vinyl than digital. Anyway,
I've posted a couple of fairly dire sweep tones (not at all easy to do):

Forgot to say I left the announcement of the *next* track on as a
'reference point'...!!

Are these a sine-wave sweep, white noise or pink noise? Reason I ask is that
the sweeps all droop towards the top end, the Fidelios fall away
drastically, so I'd like to know what is *should* look like.
