Eighty CD's... high Definition... seriously though, you're better off investing in a turntable and amp if you're really into music. Vinyl is only slightly more than standard CD's and you have just about every title to choose from, no limits there, record it at 32bit float and you're set.
Analogue trumps digital all the way. Is what those expensive DAC's are trying to reproduce .lol.
It's bloody hard to fit a turntable in your pocket though!
