Re: your greedy grasp should always exceed your ability
Actually, there are turntables out there with built in DACs that encode and transmit the analogue output from the stylus; also TTs with optical outputs, USB outputs and various other modern conveniences.
As for all the sneering at HiFi, I enjoy listening to mp3's but I also have a (once upon a time) expensive HiFi set up; parts of which are now over 40 years old.
It is not that mp3 sounds "bad", it just misses bits out (no pun intended); the enjoyment you get from listening to even a fairly low end "proper" HiFi system is the EXTRA detail you can hear. Sometimes you are not even concious you are hearing more, but realise later that it sounds a bit richer, or smoother - or you just seemed to enjoy it more than usual.
I agree with one of the posts above, mp3 is more than good enough for 90% of all music listeners, their players, car radios and micro systems cannot even extract all the detail from a low bit-rate mp3, so a "better" format would be wasted on them.
I also agree about the snake oil, though you missed one of the best - tiny black triangles that you were supposed to stick on everything to give a miraculous improvement in sound.
A proper HiFi nut gave me a sample set, they are still making my 650Watt electric drill sound superb.
(Really, I stuck them on the plug as a joke)
