Do you not have to have extremely good hearing to make it all worth while?
One of my cousins spent a fortune on high end kit and to be honest I could tell the difference between my mid priced set-up and his but not that much and certainly not enough to spend more money. I suppose if I won the lottery I would but for the moment happy with my Sony kit, Walkman and PURE radios
Mind you I am a bit of a luddite when it comes to wine as well.

Pete,
to a degree, yes. A combination of goodish hearing and training is needed: SWMBO used to play the Oboe in vrious amateur orchestras and knows what she expects to hear.
But if you cn't hear the difference save your money.
Like you with wine anything more than about £10.00 a bottle is totally lost on me, I can't tell the difference beween £10.00 and £40.00, I have a very poor sense of smell and taste.
But I can tell the difference between cheap fizz and good champaine ony because the good stuff isn't as acidic and doesn't give me heart-burn!
