View Full Version : Wired or Wireless?

Hello,

I have been enjoying Squeezebox ("SB") for the past few weeks and been
impressed with its easiness and flexibility. Yesterday, for the first time
since SB purchase, I compared the same CD between SB and my hi-end CD
transport. The CD had been ripped via iTunes in WAV format with USB Plextor
Premium CD-RW drive at its highest speed without "error correction". The PC
is brand-new Dell 8400. SB is wireless. Signal strength is between 50 to
60% (PC is in the next room). The CD is brand new classical piano solo.

Long story short, to my ears, using CD transport sounds more open, dynamic
and detailed. Scoreing the hi-end CD transport at 10, SB sound is, like, 8.
Not surprising (well, sort of...), but is this because (1) wireless signal
is not strong enough? (2) ripping speed is too fast? or (3) something else
(SB parts quality, etc.)?

I will try tonight with a patch cable for wired connection, but has anybody
else done similar comparison? Any opinion on this?

Thanks, as always.

Ken,

My guess would be the sound production hardware on the SqueezeBox.
Since you're ripping in a lossless format, it's all digital until it
hits the SqueezeBox sound production.

You could eliminate this possibility by using the optical out. I don't
know - does the SqueezeBox dynamically pare down the data if throughput
is low? I would think you'd just have dropouts...

Keep in mind that by default, Slimserver transcodes lossless files to
320kbps MP3 if you're using a Squeezebox wirelessly. If you're sure
that you have sufficient signal strength, you should disable that;
it's in the Player Settings on the web interface.

Also, have you disabled the volume control for the digital outputs?

I would suggest ripping it again with error correction (or even a
totally different program. I'm a linux person, so cdparanoia would my tool of
choice, but I hear good things about EAC (exact audio copy) on windows.)
Remember that pulling CDDA data from a cdrom drive is pretty much a hack. It
is highly error-prone.

Make sure all the fixed-volume settings are set on the Squeezebox. If
you can still tell a difference, try it blind.
