Thanks Alan.
Youve confirmed what I have always said.
Being open minded I'm almost
starting to feel a little foolish. I'm going to repeat the exercise again
with
some even more upmarket cables to see whether I really could hear a
difference
or wheter I just wanted to hear one
;-)
For Analogue Audio, good screening is a must and low capacitance if
you
dont want to loose the higher frequencies. Or you can convert to a balanced
signal and send it for long distances over two bits of wet string.....well
not
quite but any old twisted pair comms cable, even telephone cable. When we
ran
Coastal Radio at the local college there was a run of 100m of normal
telephone
cable from the studio to the refectory for an amp that we placed in
there.
Don't forget skin effect too -
which is why teflon seems to be used almost universally now except in
the
cheapest of cables.
Even
BiWiring is of limited but noticeable benefit. You are effectively just
putting a much thicker cable to feed the speaker but as long as they are
still
being fed from the same amp you can still get cross modulation from heavy
bass
transients that will cause audible effects on the higher frequencies.
You
can but - and this information comes from an amplifier designer, and
there
are always tradeoffs to be had - there is a benefit to using one well
designed
amp per channel - and you then avoid stereo cross talk. Of course the
best
way is to use four mono amps
;-)
When
I get time I will send Tim a set of KAT5 modules to try on his Plasma
screen.
I would be interested to find out what he thinks of the quality. Mark
Harrison
was suitable impressed with the Audio performance and I know what others
think
of the video performance. I would also be interested to find out how much
Tims
Component Video lead set cost. Probably more than my TV
!!!
£200 retail, but I managed to get 50 quid off. I
did
look at cheaper cables but with them there always seemed to be (small)
losses in
resolution. Interestingly the Panasonic Plasma suffered from an Svideo
timing
error, which I've been working with Panasonic UK to fix using the service
menu.
We finally got there on Wednesday, and what a difference! There are now
only
subtle differences between Component and Svideo. I'm using Supra Svideo
cables -
can't remember how much I paid for them, but they look expensive and have
got
meaty plugs on the end, so they probably are :-)
Tim.
