I was flicking through "What HiFi" magazine and I came across something very
odd - a series of reviews on *digital* audio cables, for connecting a CD
player to an amp.

There are comments such as "this cable brings across a crisp sound a cut
above the rest"

Now, at this point I have to shake my head in disbelief. Surely a digital
cable about 1 metre long can easily carry a 1mbit data stream with no
errors. Bear in mind ethernet has to carry 100mbits.

It got even worse when they talked about optical cables. There is absolutely
*no* way an optical pulse can be distorted sufficiently over 1 metre that it
could result in an error.

I can only think that the testers suffered some sort of placebo effect, or
they are in cahoots with the industry in order to provide a supply of
customers who will shell out £350 for the "best" optical cable.

Which brings me onto CD players. I always thought that amplifier and
speakers mattered the most, but What HiFi reckons CD players are important,
and worthing spending loads of money on. Now, if you have a CD player in a
half decent Hi-Fi setup then you use a digital interconnect, so really, all
the CD player is having to do is read the raw data off the CD and feed it to
the Amp, and the cleverness of its own DAC is neither here nor there.

So in a £1,000 CD player are you paying for a great DAC (which you won't
use) or simply some very good error correction in the reading process?

I just wonder if this magazine is just designed so that the industry is able
to flog expensive kit.

HiFi mags have to survive, and for that they need advertising. Advertisers like
to see plenty of star ratings and quoteable comments. Think simple - it's the
magazine that wants to survive. There is no UK Hi-fi mag that is truly
trustworthy in terms of blindfold tests. It's just not done in a scientific way
- nobody wants to do it that way. And despite Martin Collom's efforts, there's
precious little true rankings. Plus the star ratings 'include' value for money,
i.e. they are meaningless in terms of absolute sound. What's new?

Not sure what you mean by the above. MC does sometimes quote a sort of
'magic number' that he makes up to represent if he thinks a given unit is
better or worse (in his view) than others. However this number has no
objective or definable basis so far as I know. Hence I am not sure it means
much as a "true ranking" to anyone other than himself at the time he said
it! :-)

Slainte,

Jim

Unfortunately, that's about it :-(

There's still room for manoeuver in speaker design, and, to a certain
extent, amplifier design. Apart from that, music is now down to
reading bits off digital media, at a considerably slower rate than
state-of-the-art. So, to keep interest up, snake-oil is the only
answer.

Excuse me? EWhere do you get the idea that a normal amp can handle a
digital data stream? Are you confused by the prevalence of Home Cinema
amplifiers with digital audio inputs?

So in a £1,000 CD player are you paying for a great DAC (which you won't
use) or simply some very good error correction in the reading process?

Both, and you certainly *should* use the DAC in the player. However,
you also get very good error correction in the cheapest players, as
they almost all use the same Sony or Philips transports and associated
electronics package.

Now you're getting it! :-)

Speakers first IMHO followed by the turntable, then the amp.

I can already feel the flames licking around me, but having listened
to a fair number of CD players over the last few years the
diffierences (once you get beyond the very cheap and cheerful) seem to
me to be very small indeed and as much a matter of personal taste as
anything else.

Yes, and maybe to persuade us that a new product is necessarily
better.
