Nah - you have distances n' stuff to woory about.

I'm no expert on this stuff, but as long as the signal stays in the
digital domain jitter is not a factor, unless it is so extreme it
causes a misread. It is when the digital stream that contains jitter is
converted to analog that by-products are produced. The DAC being,
essentially an analog

UDP is not faster than TCP. What games, and video streams gain with
UDP is timeliness. The older the game state packet is, the less
important it is to what's happening now, so who cares if it's lost.
This is why real-time applications like games and video use UDP.
It's sad to

Nice reply ;-) I will take your advice
Regarding Fibre and the internet - the reason it appears to be
flawless is a thing called TCP, checksums etc (I.E error correction)
not a good comparison.

Mike - if the fibre didn't work properly (which it does) the Internet
would grind to a processing halt as it is constantly reconsituting the
damaged packets. Yes it happens occasionally of course. The point is
that you only need about 11Mhz of clear bandwidth for

I understand why a digital fiber cable can sound poor. Bad connection,
reflections, badly polished ends etc etc.
But I do not get why coax should sound that different from each other.
Why should I pay £100 on a cable? I don't understand (apart from bad
connections)
A perfect digital signal consists of two voltage levels and infinitely
sharp, perfectly evenly spaced transitions between them. In S/PDIF
digital audio signals the DAC reconstructs a clock from those
transitions. If the signal was ideal the DAC clock would be perfectly
regular. Instead,
Cheers guys - interesting. You may have saved me some cash.
Must admit I have messed around with my fair share of speaker and
interconnect cable over the years and there are differences - agreed
minor. But the digital side, as you say can make very little
difference?
So - would you say fibre

I'm getting a bit repetitive, but spdif vs toslink is system dependant
and both can sound good or bad - depends on system. There is so much
twaddle talked about toslink, nobody ever stops to ponder the fact that
the entire Internet is powered by fibre and bit errors would be pretty
obvious...

Just borrow something like a Chord Digi Signature Coax and compare it to
your el cheapo, depends on your system and ears of course, if you hear a
difference, you do, if you don't, you don't and saved quite a bit of
cash.
If you are interested in hearing if there is a difference try a
