I'll have to agree with that. I think the only RS gear I own are some
communication radios (for the farm) and an old Micronta analog VOM. They all
work exactly as advertized and I am satisfied with those purchases.

The other night I was at the Mall, shopping with the family, and I was able
to pop into the RS store and pick up a couple of parts I needed to finish a
project later that night. Now that's very convenient and definately worth
having.

I'm glad folks support them. I'm glad they make enough money to have a
bunch of local stores that stay open and carry parts. I just wish they
stocked more parts and parts of higher quality. I would pay more for
the convenience.

Has anyone connected an error counter to this kind of setup

I would on the other hand have liked a transmission standard that

to be different than they should be since a D/A is really just a bunch

Can anyone recommend a disc with a good sample of recorded spoken voice?
Preferably a variety of male and female voices?

I've not yet heard human voice so realistically reproduced that I can close
my eyes and imagine that someone is actually in the room talking. But I'm
not sure how much of the effect to attribute to hardware or to software. FM
radio seems the most egregious -- as if it were an industry regulation that
all announcers must be given "presence" in the form of a very artificial
bass boost. TV is usually as bad. Some movies on laserdisc can occasionally
do much better, but movie makers are well known for creating a nearly
completely artificial soundscape. (Hardly a sound you hear -- a fork
clinking against a plate, footsteps, doors closing, etc. is recorded
'live'. These simple aspects of reality are treated as sound effects just
as much as a phaser or transporter in Star Trek.)

Even the narration on some classical CDs seems to fall into the 'announcer
syndrome'. So if anyone can recommend a well-miked, untampered,
high-quality spoken voice recording, I would greatly appreciate it. Thanks.

For optical links, the cable isn't important.  It is the different

Sorry if this is a FAQ, but I searched the FAQs for "skip" or "jump" and
came up with no matches.

I have a Yamaha CD player that isn't doing so well any more. It skips very
much like a turntable would if you were jumping up and down in the same
room. Some CDs are worse than others, but they don't always skip in the
same places. It seems to get worse the longer the player has been on,
though sometimes it starts skipping right after it's been turned on.

My questions: 

Is it worth taking it into a repair shop, or is it just time for a new one?

Is there anything I could do myself to rectify this problem?

The expression 'absolute phase' has been used here to refer to 180 degree
phase shift (or, more precisely, the lack thereof), and thus to mean
correct polarity, which I would think is an appropriate use.

But, you are using a lot more of the bandwidth on a LAN; there is less
margin for error (longer time delay,higher carrier freq.==worse jitter
"phase angle" ). In DAC's for audio, you are not even that close to
the limit! While the cable can cause jitter, the relevant question is
does the jitter corrupt the digital pulse train timing? If not, it
should be irrelevent to the output of the DAC. Also, you are not concerned
with "collisions" in audio; there is nothing to corrupt the signal other
than outside interference. Therefore, unless the cable is improperly
terminated (reflections, bad rise time, etc) the DAC should give the
same output no matter what the cable composition or length, within
bounds of S/N, as JJ mentioned, with only a microscopic time delay
as a function of length...

Regards,
Gordon.

Why bother if there is only 1 error every day?  I'd rather spend my
design budget lowering jitter and power supply noise in the DAC.

Of course I'm assuming reasonable transport/ADC seperation (1 meter) in
a reasonable environment (your living room).

	I've only perused a couple of posts to this thread. Here's
$.02 on one possibility of why digital cables sound different.

	What is liekly going on is a systemic effect. Due to the
bitstream being passed through the cable there are likley eddy
currents and resonances being set up. Along with this comes
varying electromagnetic fields. It is likely that these effects
are leaching into the d/a electronics. Different types of conductors
and insulators will cause the types of resonances that are setup in 
varying cables to be different. This may be one reason why cables
sound different.

No, I was paraphrasing a response, and not to you specifically.

I'm quite well aware of how they work, I've designed them (systems-
not chips).

The issue revolves around the audibility of jitter within
the acceptance region- where bits are correctly recovered,
but precise timing varries.  That's all I was pointing out.
Bits _can_ be recovered with some jitter, and this jitter
can, if not corrected, modulate the final DAC output.

No, because in my example they were recovered correctly.
The problems are _analog_ in nature, not digital.

Many tests have shown that this is a rare case and not the cause
of many alleged sonic differences.  Too extreme.

Digital transmission and recognition over that big 2 feet is trivial.
Witness your telephone or computer.  And for telephony, jitter is
far better treated than it is in CD audio systems - look at the
requirements for TR-NWT-000253 or the CCITT / ANSI SDH.
