Vipros is correct
Because of the inability to produce a lot of bass (the grooves would be too 'wobbly', there's a standard equalisation curve (the RIAA EQ response) which is applied to playback of vinyl. Because of surface imperfections, the signal to noise ratio of vinyl is pretty poor. CDs have a theoretical maximum S/N ratio of 96dB, which is pretty good, and they can reproduce the full audio spectrum without needing corrective EQ.

So technically, CDs are far better.

Subjectively, people say vinyl is warmer, and they prefer it. Fine. It's just like using a valve amplifier. Valves add subtle even-harmonic distortion to the sound, so it's a less accurate reproduction but can produce a sound more pleasing to the ear.

Personally, I prefer digital. Uncompressed is best, but 160kbps AAC is pretty good.

128kbps MP2 (as used in DAB) is however abysmal, and should be destroyed in a massive fire.

Yeah, we know your opinion on DAB!

Have I perhaps
mentioned it in passing...?

the valve amp thing is an interesting one
I've got a Fender valve amp, and a Marshall transistor one.

Distorted, My strat sounds best with the valve amp and my ibanez with the marshall, clean however and there is no comparison between the two. valves win, hands down

Yes, but
even clean, the valve amplification will still add a small degree of distortion. And it's that which gives you the desirable sound.

this is true
and desirable it is.

I was amazed at how loud it is. I've got a 15w valve amp, and I reckon it's as loud as my 100w transistor one.
