Read: '-far- exceeds -everyone's- hearing range'. Unless you are a
young dog (some breeds) or a dolphin. But hairy ears and water as a
medium bring their own problems.

Of course it's not abandoned. But even if it were possible to support
24/192 I'm not sure there's a real reason to do so. Can anyone
actually ABX accurately between 24/96 and higher sample rates?

The only player that can do 192/24 and works with Squeezebox Server is
VortexBox player. We have gotten some amazing results using a high end

If I did not have the source material, I would not raise the issue,
I have about 30 DVD-Audio disks with 192/24, plus, there are some new
HRx titles 176.4/24
It is not that I love 192/24, I hate to downsample material.
I heard HRx 176.4Khz on Weiss, and it sounded better than same
downsampl

Will the audio out of the Touch be as good as the Transporter?
What about the power supply? Is it as clean as the TP's?

In addition there is the possibility of hardware issues. The hardware
has to have clocks that can run fast enough to support high sample
rates. The DAC chips require a clock that is a certain multiplier of the
sample rate in use. A circuit designed for a max of 96 MAY not be able
to generate fast
If you want to work on insane sample rates, your best bet is to talk to
John Swenson who is working on doing this for SB Touch, since the
firmware for that is open enough.
The ip3k firmware can never be open-sourced unfortunately, as it
contains proprietary code from Ubicom.

This makes zero sense. Its an EOL product. Live with the bugs, or buy a
new product that does what you want. Perhaps if the TP was new, but its
not. Moore's law has marched on. There are better D

did you check personally?
I hear these things every day..
Just last week I sat with our programmers and we improved algorithm 10
times.
Things can always be improved, I do not buy it.
Since nobody is working on the transporter firmware, why not release it
into public domain?
