Why not just use a good quality DVD and record in DTS? Or am I
missing
the point?

It
depends on a number of things - there is more than one way to skin a cat
and
there are different algorithms used to convert the digital bitstream into
analogue data. Without getting too technical higher resolution converters
will
push any smapling noise way outside the audible spectrum. Components in the
analogue stages will also have an impact on the final sound achieved. There
are some awesome single box players around the Marantz CD-63 KI sig being
one
example that springs to mind. There are also advantages to having two
seperate
power supplies, and keeping the transport on conversion circuitry in two
seperate boxes. This does assume though that you are feeding a digital
signal
into a good quality D-A converter, and not a 200 quid Sherwood job from
Richer
Sounds.
As
to digital cables, a number of people cite the PC as an argument for why
you
shoulc only use cheap digital interconnects. The CD-Rom to system board
cable
in a PC uses a different method of transferring data to that between a
transport and a converter - it is a 20 way (?) ribbon cable compared with a
pair of conductors in an audio cable. There are measurable differences in
analogue cables. Skin effect for one which is caused by the
interaction
between the surface of the conductor and its insulator - which effects the
timing of different parts of the audio spectrum - I think that HF travels
more
slowly than LF but it may be the other way round. While some people may
find
it difficult to tell the difference between cables in the Audio domain,
connect up a high quality display device using different cables and more of
us
will spot the difference imediately ( Ihave to say that I've got 200 quid's
worth of component cables between my DVD player and plasma) Noone is quite
sure why digital cables sound different. Jitter, or timing errors is the
most
commonly cited reason.
I'm
opening myself up for some critisism here, but I have an esoteric cable
running between my CD player and digital pre-amp, and there is a difference
between that and cheaper cables. I did audition it blind - I didn't know
which
was which when comparing the two.
If
you want to know more there is an excellent book available (Amazon stock
it) -
The complete guide to High End Audio by Robert Harley ISBN
0-9640849-4-5
My
advice? Don't go there it starts to get *really* expensive. Even Phil would
have a hard time sneaking some of my kit past SWMBO.

A bit off topic but I know we have some audio
buffs out there.
What difference does it make to the sound
quality between using an expensive or cheap CD transport or interconnect
lead assuming the AtoD conversion is being carried out in the
amp, surly the data is digital,its ether there or not so how can
it be changed by the hardware?
