[Rwp] EQ, frequencies, spectrum analizers?

[Chris Smart]

Hi Patrick. That's very interesting about 44.1 versus 48.
Does 48 just seem clearer in some way?

I've heard some 192K stuff and have several SACD's. For me at least, 
I can't separate out any differences in better mastering of the 
recordings, better converter designs etc. from actual audible 
differences in sample rates. I suppose I could downsample some of it 
and see if I detect anything.

When I was a kid, I'd walk into the local library and they'd have 
maybe two dozen CRT's switched on. It was dizzying, headache 
inducing, and not at all fun!
