Hi.

There has been a review on ethernet cables in one of the biggest German
audio magazine called Stereo.

They pretty much concluded that ethernet cables can make a pretty huge
difference!

Looking at the expected responses in this thread so far the myth that 
ethernet cables won't have any impact on the receiver needs to 
get busted.

There are several sources around that subject causing certain issues. 
Those sources are not directly linked to the actual data values.
Everybody should know that the ethernet "data" transfer is lossless.
Which doesn't mean that this happens "effortless".

The non linear stream ( e.g. caused by different load conditions), the
stream management on the receiver and even HF noise fed into the
receiver
are potential sources for (indirect) distortions. ( Did you ever
experience what a loose fit RJ45 can do to your sound?) 

In above mentioned review a german company called Meicord found out
that

a. the way a typical ethernet cable is terminated at the receiving end
is
causing severe reflections due to impedance mismatch

b. that crosstalk effects might also have an impact (they compared
different cables with different specs)

c. unshielded vs. shielded cable consistantly sounded different (the
shield
builds a ground bridge into the receiver) 



The result of that review was that the unshielded Meicord cables 
consistently sounded far superior than all the other cables in the
review.

I'm currently using DRAKA UC900 with Hirose TM31 connectors (CAT6A). 
I cut off the cable shield at the receiver side to avoid a ground
bridge.

The review also stated that a. such a difference would not been
expected and
b. that explaining exactly what's causing the difference would be kind
of difficult.

The experienced differences on different cables though, are
unquestionbale.

I'm gonna get a set of Meicords next week for testing. I'll let you
know
about my findings.


And after all wire still beats wireless (if you use my toolbox)


Cheers
