Hi
just to note I am using basic (certainly not exotic) quality coaxial to
stream digital output over 3 rooms via the loft for the past 5 years;
probably around 50m with negligible deficit. why not stream over
squeezebox? Well SB doesn't accept digital input eg from a cd player.

Darren, you simply have to try both and see which you prefer. There are
no hard rules, it depends on the DAC.
As for glass vs plastic... for the lengths we are talking about it's

Actually Steve says it should either be greater than 1.5M or very short
(less than a foot).
ALL the TOSLINK interfaces used by everybody are all made by Toshiba
(hence the TOS part) they only offer a fairly limited range of devices.
The receivers come in low bandwidth and really low bandwidth.
After reading some internet discussion a year or so ago, I compared an
Amazon Basics TOSlink cable (about $8) to a Canare/Neutrik 110ohm
AES/EBU cable in the digital effects loop of my Transporter.I just
wanted to hear the STAGGERING differences for myself.

If the length of an s/pdif cable makes a difference to your DAC, don't
buy more s/pdif cables, sell your DAC and buy one that works properly.
Why throw good money after bad?

Understand that if you actually
The reason for the =1.5m length has to do with controlling signal
reflection due to impedance discontinuity on the receiving end. For
example, my TacT 2.2xp has poor internal construction in terms of
impedance control. A 1.5m cable sounded significantly better than a 1m
cable from my
As I mentioned on the other thread I'm trying a 1.5m coax versus 0.5m
optical. Not sure if the optical is supposed to be (according to
theory) =1.5m or 2.5m or whatever...but I went short anyway. I'm
guessing there aren't mirrors at the ends of the sockets!

What about optical cables - is length significant and why? I hear glass

So, coax versus optical on the SB Touch - does anyone have any
comments?
Can it not be dependent on the gear you are using some tos transmitter
and recievers are not fantastic they say ?
making the the optical interface having less bandwidth than the
electrical interface that's a pity it has potential to be significantly
faster.

Proper 75ohm cable termination would indeed do the trick.
But since most SPDIF connections use RCA plugs/sockets, that's a moot
point - the basic geometry of an RCA connector means 75ohm is not

Griffin,
Sorry I should have made it clearer.
SN says these cables SHOULD be at least 1.5m long. DL says that's wrong
- there is no minimum length like that and in fact shorter is better.
These are the two conflicting views I've read.

That is about the weirdest thing I've heard in a long time. What is his
reasoning for recommending a minimum length?
I'm not at work at the moment, but I'm pretty sure the standard doesn't
mention a minimum length.
