You might like to make sure you're not bit rate limiting to the SB3.
Looking under Player Settings|Audio - make sure Bitrate Limiting is
set to No Limit.

Other than that, how are you connecting the SB3 to your audio system?

What you explain here is certainly not the cause.
The network protocol makes sure that the data arrives at its
destination intact. It is almost impossible that the SB3 receives bad
data because of the network connection used. 
If the SB3 received corrupt data it wouldn't play any sound at all
because the decoding of the audio stream would just fail.
Doesn't the AE rely on the same network anyway?
What makes you think that the connection G5 - AE is more direct than
slimserver - SB3?

What kind of amp do you use?
Are you sure the AE doesn't artificially boost highs and lows?
The SB3 is quite neutral in its presentation but it isn't muffled in
any way.
Does the AE boost highs and lows so much that you had to turn down
treble and bass on your amp?
Do you use the same inputs on the amp with the SB that you used with
the AE?
You don't use the phono inputs by any chance?

 I recently purchased an SB3, largely upon the strength of discussion of
 this forum.  I appreciate the modest origins of Slim Devices, and the
 audiophile community's support of the Squeeze Box.
 
 Also, I had started with a Roku Soundbridge, and discovered that the
 sound was muffled, with a narrow dynamic range, compared to my old
 Airport Express.
 
 So tonight, I'm wondering why I'm getting largely the same results with
 my SB3.  Listening to either internet radio or streaming through slim
 server reveals the same results: my music sounds like a slightly
 muffled FM broadcast compared to the pleasant, full CD-like sound
 that Im getting from my Airport Express for exactly the same music
 (Internet Radio, FLAC, MP3).
 
 I've read the posts here -- no one has ever reported back that the
 sound on an AE is better than the SB3.  I've tried both analog and
 digital out but the result is always the same.  The AE provides the
 fullest sound (with better highs and deeper lows), followed by
 over-the-air FM, and finally, the SB3.
 
 My only possible explanation is that broadcasting from my Apple G5
 directly to the AE via Airtunes somehow provides a more unaldulterated
 sound compared to using the SB3 off of my 801.11g network.
 
 I'm not an audiophile, nor do I own high-end equipment.  But I detect
 clear differences between the SB3 and the AE.  I really want to like
 this device, and I know how positive an experience you all have had
 with it -- so I'm just hoping I'm doing something wrong and there's an
 adjustment I can make to make this work.
 
 Thanks in advance for any suggestions you might have.

I'm also curious as to how internet radio can sound he same as
Slimserver-based audio. Internet radio stations can be 'broadcasting'
at 64 Kbps, which generaly sounds horrible, whereas you have the choice
to listen to whatever bitrate you choose, and you have not disclosed any
details about your own audio. You need to compare apples with apples, as
they say

 i find there is a tremendous one - on my equipment the RCA connectors
 definitely sound more powerful and fuller.
 
 but apparently (according to other users) this differs depending on
 your audio equipment.

Yes, there's a significant electrical difference. The RCA connectors are 
line out -- straight from the DAC. The headphone jack has a (cheapo) 
headphone amp on it. Always use the RCA line out to connect to anything 
except headphones.

I had a terrible shock when I plugged my SB in. It sounded terrible.
Only by accident did I discover that this was because I'd plugged it
into the amp input designed for vinyl. I plugged it into 'video'
instead and it's great.

Re: [slim] New SB3 user, why does Airport Express sounds better?

2007-11-22 Thread minstrel

Thanks everyone for sounding off.

You're right, it could be a subjective opinion, and the SB3 is
delivering, a flatter, more authentic signal.

I'm connecting the SB3 via a TOSLINK digital cable to an Onkyo CS-V720
system (a miniature consumer set, but highly rated for sound in small
spaces).  I've connected the Airport Express via analog to the same set
(RCA Line In), and have the ability to switch the inputs back and forth
while listening to the same station (using my Mac for the AE, the
Squeeze Network for the SB3).  Finally, I've also compared the two by
using the AE on digital (Toslink) and the SB3 on analog (Line In RCA).

I've dialed up KEXP and Radio Paradise (both at 128 kps), and I easily
detect the difference.  I also find that FM generally (I live in
Seattle where KEXP is based), is brighter and more pleasant to listen
to than the SB3.  And I've got the bitrate settings set to No Limit.

I'm an independent filmmaker, so am used to working with flat, neutral
sound while editing.  Still, it's possible that I expect something more
enhanced as a consumer/listener.  I guess I was just expecting a marked
improvement over the Roku after everything I read about the two. 
Ultimately, my sound equipment may not be good enough to distinguish
the two.

I'll give it a couple more days before I make a decision.  This is a
great community, and I really like the look and feel of this device, so
I hope I can figure this out!

So...you're judging the SB3 but actually listening to the performance
of the DAC in Onkyo?

Re: [slim] New SB3 user, why does Airport Express sounds better?

2007-11-22 Thread Mark Lanctot

The Onkyo may be doing an additional A-D conversion, see:

http://wiki.slimdevices.com/index.cgi?AVReceivers

(I realize it may not be an AV receiver but it probably uses a DSP all
the same.)

Try:

- selecting DIRECT, SOURCE DIRECT, BYPASS, etc. modes that do not
process the signal.  On my receiver SOURCE DIRECT brightens the sound
tremendously, so much I don't like it.

- connect the SB via analog and use one of the modes above

Also you may want to try listening via headphones to the SB3 headphone
jack just as a test.  That's the purest analog method there is and
you'll at least see if the Onkyo is messing with the signal.

Re: [slim] New SB3 user, why does Airport Express sounds better?

2007-11-22 Thread minstrel

Alright, I took the advice of this forum to heart, and decided to
properly assess the sound -- by putting on a set of professional
headphones.

That made all the difference. The expansive, dynamic sound I thought
the AE had, comes across as breathy, overly-enhanced, processed, and
with audible compression artifacts on the highs.

The SB3 on the other hand plays clearly and evenly.

I suspect speaker placement and my listening environment (hardwood
floors, lots of windows) might have given me the wrong impression of
the AE sound.  Headphones reveal the truth.

Thanks again for everyone's input.  It's a keeper.  One day I'll get a
proper DAC, but this will have to do for now with a baby on the way.

minstrel, amcluesent makes a good point.  -If- (and only if) your Onkyo
has a direct analogue path, try using the analogue output if the SB3
into the analogue input of your receiver. The SB3 has a pretty decent
DAC and may well be better than the one in your receiver. Watch though,
some receivers convert analogue inputs to digital for processing through
their own DAC and three conversion processes isn't likely to enhance the
audio experience. 

Also, it's likely that all those hard surfaces in your listening
environment are reflecting sound all over the place which isn't good
either.

You might be surprised to discover that you already own a proper DAC --
the DAC in the sb3 is rather impressive.

I find this interesting.  I'm not surprised that the Airport Express is
tinkering with the sound more than the SB3, and I'm also not surprised
that on a superficial listening, with a lossy source like Internet
radio, that it sounded better.  I'm not even going to be too critical
here--for its market it's probably well-positioned and engineered.  

Interestingly, the SB and my receiver (Denon AVR3805) actually have the
same DACs, so I notice very little difference between analog and digital
inputs.  Just a great clean sound that's blown away any CD player I've
owned (not being an audiophile.)
