Well, there IS an electrical connexion between the switch and the
SB/TP. One probably needs proper equipment to measure any differences
(and to know what he's looking for). ;)

Now to see if some company comes out with an "audiophile" grade switch
that sells for a zillion dollars and delivers heavenly sound because of
the unobtanium used in it. 
On a more serious note, it is perhaps worthwhile to take a closer look
at different types and quality of switches on the market. Maybe someone
on the forum with technical expertise may look at the possible reasons
for switches affecting sound quality, could it be the topology or chips
etc?

Nice to see your problem was solved. Understanding why is not

short answer as everyone else has said before in this thread, NO

Long answer:
TCP data streams have have error checks, so in order for noise to
introduce an artifact WITHOUT causing an error it would have to change
the data and checksum so that it still passes.  EXTREMELY unlikely to
happen from noise. So unlikely that many will tell you it is
impossible.  Now you might think well maybe it was causing errors to
happen.  If this was the case the problem you would see is sound
dropouts and/or the squeezebox disconnecting from the server.  You
would NOT get subtle audio changes in the sound.

Now then it is still not out of the question that maybe the PSU on the
switch was introducing noise elsewhere that effected your amp or
squeezebox, however you said in your tests that you left it powered on.
So that pretty much invalidates that theory.

Re: [SlimDevices: Audiophiles] Good sound from Squueezebox

2008-12-16 Thread jeffmeh

So there must be something very wrong with your original switch, if your
new router sounds significantly better.

Regarding WAV sounding better than FLAC, this has been discussed
before.  The only explanation that is plausible is that when the SB3
natively decodes the FLAC, the act itself causes some change in the
device's electrical properties that affects sound quality somewhere in
your audio chain.  Certainly possible, and some swear that it is true,
but others cannot distinguish any difference.  Personally, I'm
skeptical, unless someone can reliably distinguish the difference
blind.  But if you prefer to transcode to WAV, good for you.  No
worries.

2008-12-16 Thread maxrob200

Ok...this is what I have found with a couple of changes

1. Changed crossover to straight thru cable on router. No difference in
sound quality. I need crossover when connecting direct from NAS to SB
anyway, so not musch choice if I choose to go direct

2. Changed to Linksys Etherfast router. Very noticeable difference.
Same as going direct! Perhaps direct may be a tad better but I'm
probably imagining it.

3. Changed decoding from flac > flac to flac > wav. There is a real
improvement as well in my opioion. More analogue sounding especially in
vocals and bass

4. Changed my amp to a Pioneer GClef A9. This amp is way better than my
current Cambridge in resolving inner detail and soundstage. Improved
sound quality quite  a bit

5. Tried a Behringer SRC2496 using Belden 1694 75ohm coax as digital
s/dif cable. Resampling at 88.2. I found no difference in 44.1 and 96
sounded edgy
flac > flac - not real good. 
flac > wav huge difference in sound quality. 
Sticking to flac > wav and 88.2

Hey, this is audiophiles. Cables make a difference. You need to test
both solid strand and stranded CAT5 cable. Double blind. etc.

Only then can you test hubs vs switches vs routers

I don't know about the other claims, but I can absolutely
guaran-damn-tee you that there will be no subtle differences in sound
quality from your network connection.  It's packetized data with error
correction.  Either it delivers correct bits fast enough or it doesn't.
If you get failures, they will be extremely obvious.  If it's not
obviously failing, it's not failing -at all-.

I suppose there's some very vague chance of poor grounding in the
switch or something.  That strikes me as damn unlikely, but you could
try wireless to see if there's any difference.  The chances are
enormously higher, though, that you're just convincing yourself there's
a difference when there isn't.  

The other changes are a bit more plausible, since they're more directly
connected to the output circuits, but remember that blind testing is the
only way to know for sure. "Sighted" testing, where you know which
signal is which, is simply unreliable for audio.

I mean even *IF* there is a difference, I'll bet moving a single
speaker by a millimeter will make a 10x as large difference. This is we
go nuts about stupid stuff when we completely don't bother fixing the
things that make a huge difference in our systems. Sometimes its all
about a peace of mind in audiophilia and people will pay $1000s to have
that feeling. We are killing the enjoyment of music (the purported
reason for all of this in the first place) with all this obsessiveness
over little things. 

Yet if someone prefers a certain much harder way of doing things in the
name of sound, then let them be. I just hope that some new person
understands what is really on. These audiophile forums can ruin the
frame of mind of a newbie in this hobby. It's all about the music and
that message should always be at the forefront.

Hi, earlier in the thread you said that you would use unshielded
network cabling - have you already done this, i.e. is there only
unshielded network cabling in use with the switch?

Also, did you mention if the switch and/or SB3 are plugged into a power

Are you sure you didn't state that backwards (based on your orginal
observation). Now you are saying it sounds BETTER with the switch
hooked up (powered on).

It was a good idea unplugging it and letting it run off buffer. Try
unplugging network cable from SB3/Transporter instead :) Eliminate that
huge antenna hanging out the back.

All playback equipment has been playing for at least 2 hours before
test to ensure adequate warm-up time.

With power OFF to the switch there was a slight drop in volume level,
there was less sibilance in the vocals, smoother/richer bass and better

With power ON, sibilance in vocals returned, flatter depth and less

2008-12-07 Thread DeVerm

No, the best way to test this is as follows: connect everything with the
switch in between and start playing a track where you could hear the
difference before. When the track is halfway, power-off the switch by
pulling the power-plug/adapter from AC outlet. Do -not- pull anything
else like ethernet-cables etc. The SB will continue playing because
there's still data in the buffer, but the switch is killed and not
radiating anything. If you hear a difference, you need a better switch,
or plug it in further away or using a different outlet. If you do not
hear a difference, you could pull the ethernet-plug from the switch and
listen for difference. You would need really big EMI if you hear a
difference at this stage and it would not be the switch but something
else, outside your audio/network-system. I would try different ethernet
cables at that point, unshielded, because you use an extra one with the
switch which may be bad (or both bad with just one connected better
than both connected; unshielded to prevent ground-loops that shouldn't
be there but who knows.

good luck,
Nick.

If the switch is causing noise on your power lines, you could try
direct-connect to the NAS, but leave the switch plugged in where you
normally keep it.  If you still think the direct-connect sounds better,
then you can probably rule out the hypothesis that the switch is
introducing noise on the power lines.

If the switch is introducing noise to the SB3 across the ethernet
cable, you could either try wireless or try a different cable.

In any case, the only hypothesis that does not violate the laws of
physics is that the switch is introducing noise somewhere.  If the
network packets are getting there in time to keep the SB3's buffer from
emptying, it is EXACTLY the same as direct-connect, and the timing does
not matter.

"Straight wire with gain" is the ideal for an amp.  I've never heard

difference is perceptible after volume matching.

Re: [SlimDevices: Audiophiles] Good sound from Squueezebox

I agree there is plenty we don't understand which is why I leave some
room for doubt always. And in general, I agree with the scientific
method whilst noting that over time science evolves, with the odd
revolution now and then, indicating that scientists at any given time
don't have it all right!

However, I believe that what is heard can be influenced by mental
factors quite easily. Whilst such a straightforward explanation hasn't
been ruled out, a tricky discussion over other possible explanations is
premature.

BTW I wouldn't say you are "imagining" anything...any more than anyone
hearing anything "imagines" it. Hearing isn't a physical object, it's a
mental process. The question is the cause of what you're hearing, not
whether you're "hearing" it or not!

Let me give you another example:
The image is received correctly but the screen has interference and
shows this image distorted when your system is connected to a switch.

The OT doesn't say that the file is not received correctly through a
switch, he claims that the sound coming out of his speakers is slightly
different. Not probable, but nevertheless possible.

things happen for many reasons in audio when people hear differences.
listening to music with a switch may sound different simply because the
power supply of said switch is horrible and introduces noise everywhere
else. 

i had a friend who preferred the sound of loudspeakers that surprised
me. found out one of his speakers had the polarity inverted when he was
doing his listening test.

i do not discount anyone's listening story in these forums, i just
sometimes wonder about the reasons why those effects emerge.

At the risk of being told again that I am imagining the differences, I
have listened to switched and non-switched playback with a variety of
music and as much as I would like to bow to general opinion, I can
still hear differences in these areas: less sibilance in vocals,
smoother sound, more space/soundstage, better bass and to coin a much
abused term - better sense of PRAT (pace, rhythm and timing) Files are
FLAC (-5).

I am using an el-cheapo router/switch(ASUS RX-3041 $30) and will try a
more upmarket unit to see if the differences that I hear currently is a
factor of the unit.

I agree that open mindedness is important. Sometimes though in the face
of "generally accepted" conclusions, some idea or experience comes
along that can cause incredulous reactions and start an alternative way
of thinking or experimentation. I have never dismissed opinions or

There has been a whole host of "incredulous" ideas over the years and
many have now become accepted facts of audiophilia.

Sure you are entitle to your opinion. But if the generally well
informed public believes it's nonsense it will be challenged. Not out
of disrespect. If it's not (i.e. folks just ignore it) then not so well
informed people will read it and believe it (seeing it not be
challenged). And do some really unecessary silly things which can
actually compromise overall ease of use, expense, enjoyment etc. Like
managing a library of wavs instead of flacs which is insane (IMHO).

maxrob200,

There's a world of difference between:

1. hearing a difference between .wav and .flac
2. "hearing" a difference when your SB is connected to Squeezecenter via 
a switch vs. direct connection.

I don't personally hear (1) myself, although I've not done extensive 
testing, but I don't dismiss it as impossible; highly unlikely, IMHO, 
but not impossible.

(2) is just not possible. Let me attempt an analogy.

You, Sean, and myself are all sitting at a table with our laptops. They 
are not connected in anyway.

I have an image file I want to send to you.

Consider these two scenarios:

1. I write the file onto a USB key and slide it across the table to you. 
You read the file from the key and view it on your computer.

2. I write the file onto a USB key and slide it across the table to Sean 
who then slides it to you. You read the file from the key and view it on 
your computer.

Do you think your computer will process the image file any differently 
in scenario (2) than it will in scenario (1)? Would you expect the image 
file to look any different in scenario (2) than it will in scenario (1)?

I am Squeezecenter.
You are a Squeezebox.
Sean is a switch.

It's not wireless, using cable.

tests within a group could be an interesting exercise.

It is interesting to note that by posting an opinion that I have now
been relegated to the "imagining things" category. As mentioned
earlier, it was not so long ago that the general belief was that all
cables sounded the same or all that an amplifier had to do was
demonstrate " straight wire with gain", so why not differences in the

Anyway, I will continue to experiment with various bits in the system
and decide whether I am imagining thingsmaybe another glass of Red

2008-12-05 Thread darrenyeats

This is about to get into a religious debate. It's obvious you don't
believe that your mind can influence what you hear, otherwise you would
wish to investigate further by doing some blind tests. Some of the
others on the forum, me included, believe that our minds can and do
influence what we hear all the time.

Without common beliefs it isn't possible for the subjectivists and
objectivists to reach agreement...but I suggest the above is the key
belief that splits the two camps.

The reasons the issues of FLAC vs WAV and the network switch
differences are worthy of a blind test IMO is that:
- FLAC and switches are handy.
- There isn't a convincing technical explanation, at present, as to why
they might sound different.
- If an audible difference exists for these, it's likely to be on the
subtle side.
All three make the idea that it's in your mind a more attractive
direction to investigate.

Yes, but this is simply not one of them.

If you copy a file between two computers connected via a switch it will 
be *exactly* the same as if you connected the computers directly.

And that's the only thing that matters.

Once the song has been transmitted asynchronously to the Squeezebox, it 
is processed internally and, believe me, the Squeezebox has no idea 
whether the file has come via a switch or direct.

You don't by chance mean "wireless access point" when you say "switch" 
do you? In which case you could have bandwidth limiting enabled, perhaps.

I want to set a static IP for the SB so that I can use it just with the
NAS, nothing to do with sound quality. At the moment, when I just use
the NAS and SB, the SB cannot locate the NAS if it has been switched
off from the mains. If I just switch cables it works fine as IP has
already been given by router's DHCP

And no, I am not imagining the sound differences between standalone and
connected to the switch.

Also IMO wav sounds better than FLAC

Like the age old debates among audiophiles about cable differences as
well as amplifier differences despite measurements being identical,
some things are in the subjective domain and will likely remain so for

I second that. IP transport is immune to "audio" effects. Simply
because it uses an asynchronous error-free protocol.

If the OT hears a difference when he disconnects the switch, there can
be only two solutions:
1. He imagines a difference
2. The switch introduces some kind of RF interference which may be
transmitted over the cable and affect other components inside the SB,
(outside the network interface itself).

As long as the music plays, i.e. your not getting breakups, pops,
crackles etc. and the switch works for other purposes, there is no way
the switch can affect sound-quality. I won't go into details, but this
is way different than any discussions on e.g. cables, file-formats,
power-supplies, dacs etc. It is beyond arguing. Whoever wrote what you
read is seriously misinformed.

Inadequade transfer speeds are not to be expecteded at all until your
switch is broken. It has to be fast enough to fill that little RAM in
the Squeezebox.
If it can´t handle that there must be something broken!
And regarding audiophiles (i post there sometimes also) Don´t take
everything as granted. Don´t do the lemming.
Me for example tried hard to detect wav to flac differences on my
Transporter but somehow i must be deaf...

This is incorrect.  A (working) switch and a (working)
direct-connection will sound identical, as the timing of the packet
traffic in TCP/IP is independent of the timing in the audio chain.  A
broken network connection would cause the SB's buffer to empty, and the
music would stop or stutter, not become subtly different.

It is possible that the switch is introducing some type of noise that
the SB is sensitive to, but that would be a broken switch.  It is more
likely that you are imagining the difference.

Hi Robin
I don't think that I am imagining it. I did read somewhere that the
quality of the switch does effect overall audio performance due to
inadequate transfer speeds or similar delays.
I have listened to both combinations and there is definitely better
audio playback when connected directly just to the NAS

Rubbish. You're hearing things.

Ok, point taken. I will use standard Cat 5 or 6
I intend to use SB with NAS only once files are uploaded. How do I set
a static IP for the SB. Is it in slimserver software or SSOTS? I have
done it for the NAS

don't use shielded twisted pair... ethernet is designed for unshielded,
and under 99% of circumstances you are more likely to increase EMI by
using shielded.
