When listening to Pandora on my Transporter via mysqueezebox.com
If I have a look at the the song details, just above the bitrate and
file format there is a display named volume adjustment usually it's
saying something like -4.4db sometimes it'll say -1.2db it changes

The point is the equipment should be able to reproduce the signal at 54
dB below full scale(or 96 dB below full scale if you claim that is the

Without dithering, the situation is easy to understand. For every bit
below full scale, the distortion doubles. And each bit is worth 6dB of
dynamic range. So if you plot the distortion (due to quantization

As to the second point do read the Pohlmann book as it explains it very
well. The point is the quantisation error is noise if uncorrelated to
signal or distortion if correlated (this is essentially a definitional

Can you go into some specifics though please?

You want to see the signal path BEFORE it gets onto a CD/vinyl...it
ain't what you'd call minimal...

That is definitely he best joke about low level DAC linearity I have

Looking at the Gator board with the bottom edge closest to the front of
the case, it's the first four grey non-polar caps on the left side. I

I use SBT with Benchmark DAC1 HDR (which is identical sonically to a
DAC1 PRE). For all practical purposes, I don't think you'll find a more
accurate (transparent) DAC or pre. I'm of the opinion that, if desired,
flavour should be added later in the chain and that

Then I'll bet there are an awful lot of people who are on their own.
Which would mean that they're not really on their own.

If you want accurate, I don't think you can get much more of it than
the Transporter, SE or 2.hand standard, balanced out and directly into
a suitable power-amp, gets you.
There are a number of good reasons for this.

A Benchmark DAC1 HDR gives a huge improvement to the Touch (ime) (imo)

Thanks guys. I know that Pandora is compressed to hell anyway, I just
wanted to field some opinions on the matter, will check the links out
later.
Anyone Interested in putting forward some signatures to petition
Pandora to finally Re-Code to a higher bitrate?
Is there an alternative to Pandora?

In case you weren't aware, they already have their Pandora One service,
which streams 192kbps. It's a subscription service for $36/year. The
drawback is that
I like Rhapsody, and use it a lot. $10/month unlimited. They're
streaming at 192kbps.It is what it is, but I like it to listen to
new albums before buying, or to re-discover old music that I'd
forgotten.Great service.
