"You Tube" sampling for classical music...

I just discovered the "wealth" of selection to evaluate via You Tube, having never bothered with the site before.
I can see what a dinosaur I have been. Yuck.
There's a world of music out there and what a benefit to 'audition' before you buy. I think we are just entering a golden era in music availability and of course the reproduction quality will be mind bogling via the new, true hi res downloads. Reference Recordings have a new system that sounds interesting. Those guys have fussy ears.
Please write further Psacanli! I have found very little on youtube, I must be doing it wrong. I would really like to check out the hi res downloads.
