Not huge, it depends if my Rega amp works, if it does then I'll just

 Anyway I fully support the idea having TP center knob behavior being

 1) current mode, should be default so former users don't care ;-)
 2) center knob is volume and user can go to navigation mode by hitting
 back button first. Center knob returns to volume after user do a play
 action or automatically after 10s of inaction.

You have to register another account for bugzilla it is not the same as

[SlimDevices: Audiophiles] Transporter suddenly dead and not responding to anything

2009-10-24 Thread Aurumer

I think my transporter is completely dead. While listening to music
today it suddenly switched off. Now it is not responding to front panel
or remote or anything other. I tried removing power cable and any type
of reset but nothing helps.
While plugging power in even the clicking sound of the sound power
relay is missing.

I immediately wrote a mail to logitech support (support form is down,
but I had an support e-mail address from some earlier warranty
communication). 

Anyone with similar experiences? I hope they will find a quick
solution.

Regards Aurumer

 We can explain how to do this when/if you are ready.

Ouch, that sucks.  I hope you hear from support soon.

It's possible the PSU fuse is blown.  If you open up the unit (don't

[SlimDevices: Audiophiles] SB Server settings advice

2009-10-24 Thread richardw

I wondered if i could get some input on the best use of the settings in
Sqeezebox Server for optimal sound quality. I use the Transporter
AES/EBU digital out to a Berkeley DAC. Files are ripped to FLAC from
redbook, no high resolution files for now, on a Windows Vista laptop
(until i decide on the best storage option). It seems the software has
evolved over time and there are many options/settings related to audio,
file conversion, sample rates etc.

Any suggestions would be appreciated.

Re: [SlimDevices: Audiophiles] SB Server settings advice

2009-10-24 Thread JJZolx

For Squeezebox Server there's no good reason to use anything but FLAC
for the file format.  Your choices for streaming the FLAC files are

1) as FLAC (natively decoded in the Transporter)

2) as uncompressed PCM, whereby Squeezebox Server decodes the file at
the server computer

The first is the default setting.  The second can be had by going to
Settings  Advanced  File Types and changing


Code:


  File Format  Stream Format   Decoder
  FLAC FLACNative
  PCM flac
  
  



to:


Code:


  File Format  Stream Format   Decoder
  FLAC FLACDisabled
  PCM flac
  
  



The disadvantage of the second is that it requires more bandwidth
(generally, about twice as much) to stream the music to your player.  If
you're using a wireless connection, this may result in dropouts.  The
probability will increase if you stream hi-res formats like this.  If
you have a wired connection, you'll have plenty of bandwidth.

FWIW, I hear no difference on my system streaming either way.  Try
using PCM and if you think it's better and you don't experience
dropouts, use it.  Otherwise, keep the default settings and enjoy.

[SlimDevices: Audiophiles] Phase?

2009-10-24 Thread kphinney

This isn't TP or SB specific but I thought I'd give it a shot here since
I can't find any real good info on it:

My DAC has the ability to invert Phase from 0º to 180º.  I can't tell
the difference.  Should I be able to?  

How can I tell if I'm in need of Phase Inversion?  

Can I buy a Dilithium Crystal Phase Inversion field to prevent
catastrophic mixing of phase and anti-phase?

I'm guessing that I need to switch it when I listen to Canadian
artists.  Or is it for Indie music or that from south of the equator?

Nope.

Some folks claim otherwise.

In theory, the kick of a bass drum should start out coming towards the
listener.

Stereohile lists whether a component inverts phase, which if you really
cared, could mean that you could find two that invert it to get back to
normal.

There are other things to worry about. IMHO, YMMV, etc.

2009-10-24 Thread SuperQ

There shouldn't be any settings you NEED to change in the defaults.  The
only thing you may want to change is to set the volume to fixed 100% so
the DAC gets the native file data and doesn't do any volume scaling.

Sending FLAC to any squeezebox is the optimal setting for quality,
compatibility, and bandwidth.

There is no sound quality difference between the coax or Toslink.  

They are both transmitting binary code not an audio signal.  If you are

Re: [SlimDevices: Audiophiles] SB3+DAC: Optical or coaxial best?

2009-10-24 Thread sgumnit

There is almost difference. Optical induced jitter through the DAC magic
should not be an issue.  And the because the DAC Magic is a 24bit system
it should handle the optional 24 bit resolution.  That is assuming that
the duets' receiver optical output is 24 bit.

Outside opinions:

http://en.wikipedia.org/wiki/S/PDIF

S/PDIF specifies a Data Link Layer protocol and choice of Physical
Layer specifications for carrying digital audio signals between devices
and stereo components over either optical or electrical cable. The name
stands for Sony/Philips Digital Interconnect Format (more commonly known
as Sony Philips Digital InterFace), the two companies being the primary
designers of the S/PDIF format. It is part of a larger collection of
international standards known as IEC and defined by IEC 60958 (often
referred to as AES/EBU), where it is known as IEC 60958 type II. S/PDIF
is essentially a minor modification of the original AES/EBU standard for
consumer use, providing small differences in the protocol and requiring
less-expensive hardware.

There are no differences between the signals transmitted over optical
or coaxial S/PDIF connectors—both carry exactly the same information.
Selection of one over the other rests mainly on the availability of
appropriate connectors on the chosen equipment and the preference and
convenience of the user. TOSLINK cables do not work well (and may even
suffer permanent damage) if tightly bended, and their high light-signal
attenuation limits their effective range to 6.1 metres (20 ft) or so. On
the other hand, TOSLINK cables are not susceptible to ground loops and
RF interference, like coaxial cables.[1] Another deciding factor for
many is cost: any standard 75 #937; A/V cable can be used for coaxial
connectivity, while TOSLINK requires a specific cable which, until
recently, was not very affordable.

So, in this scenario the grounding is an issue and the Toslink is
resolving his problem.  Otherwise, the Coax is an easier and cheaper
alternative.

Please remember there isn't always THE answer, sometimes there are
multiple best solution answers.

No. Governments go to great lengths to keep this away from the general

catastrophic mixing of phase and anti-phase, and why would you want to
do that? This dimension is so much fun!

In theory, yes.

However:

 They are both transmitting binary code not an audio signal

They are actually transmitting an analogue signal that contains encoded
binary code including the timing information. It is possible for this to
be affected by both the SPDIF transmitter/receiver and the cable.

So, it's not quite as simple as there are no differences.

Actually, the Dilithium Crystal should allow for non-catastrophic
mixing of phase/anti-phase.  To quote -The Mineralogy of Star Trek- by
Jeffrey de Fourestier, et. al. (Ottawa, Ontario)  ...when dilithium is 
subjected to a high frequency electromagnetic
 field, it becomes porous to antimatter, and that it is the only
 substance known to possess this quality. Since passing through its
 crystal structure slows down or moderates the flow of the antimatter,
 dilithium can be used to moderate the reactions in the matter-antimatter
 reactors.

I think I may have found a DIY starter here:

The Rotel only had a coax-out and my DAC had both coax and optical in,
so now my SB3 is optical into the Dac and the Rotel is coax into the

Keep your options open:  a good cable is at the lower end of the price
scale of upgrades.  If you can get your hands on a good Coax and a good
Optical then you can cover all bases.

Dont put the DAC on the amp. Dont put anything on the amp.

First of all - The Rotel is second rate. Sorry - I had a Proton back in
the 80's. It was great so I thought. It's all relative. When you get
into the real stuff you are going to put your Rotel up for sale
lickety split!

My bias is get the hell out of class A/B. Either go tubes, or class T,
D or pure class A. I tried mosfets - no way - I'm into class T now and
I'm not turning back. I though about tubes at one stage but cap tweaking
has done the trick. 

The Transport is one awesome sounding front end. Work on the other
stuff and dont bitch about the Transport!
