Please excuse my ignorance, but what is a 5532 and a TL072 ? What
problems are they causing ? I know I could look it up (and I just have)
but others may be curious too. I find all this interesting.

You'd be surprised (or perhaps not) how many people really aren't
bothered about hearing nice clear audio through a decent system, never
mind the (small?) distortions we are discussing in this NG. Sometimes I
think its because people don't realise what they are missing. Even with
my modest set up, I've bought a smile to the face of some people who've
sat and listened to my relatively good system, compared to your average
low end extremely coloured systems (complete with "3D" sound
"enhancement" and all that)..

I think others who refer to us, who do care, as anal about it perhaps do
not appreciate music in the same way. To me there is nothing better
than hearing the subtle beautiful tones of a well recorded well played
piano or acoustic guitar; these are just plain invisible or distorted on
a lot of todays cheap crap, and people are getting used to it.

Disclaimer: IMHO, YMMV, etc.

Cheers.
