[Article] Analog vs Digital

There's an interesting article on the Economist on the
difference between analog and digital equipment.

http://www.economist.com/displaystory.cfm?story_id=126146...
Snippet:
Several years ago, a roomful of engineers performed a
series of blind tests on a stack of reference recordings to
see if they could distinguish those made using tube
technology from others made with transistors. All imagined
they would have little trouble picking the tube-based
recordings by the warmth of the sound. What they found
instead was an ear-opener.

In fact, tube-based amplifiers have about as many different
sounds as there are designs of amplifier circuits. The
recording ultimately depends on which components the
designer used in achieving the sound he wanted.

If anything, it’s the transformer in an analogue
amplifier, rather than the vacuum tubes themselves, that
create the illusion of warmth. Early solid-state amplifiers
also used transformers—and they, too, were said to produce
a warmer sound.

What we know about transformers used in amplifier circuits
is that they add a measure of distortion to the signal’s
lowest frequencies, and restrict its highest frequencies.
Also, like magnetic tape, transformers suffer from
“hysteresis”—the non-linear way magnetic materials
behave when their polarity reverses.

the thing is, you can sort of emulate that warm analogue
sound by using digital equipment, but why bother when you
can get cheaper analogue gear and just make music with that?
looks interesting, i will give it a read later, but it will
probably go over my head cus i can't remember all the tech
stuff i learnt about sound
