Badwater,
The update to the VDA.2 was announced last November. Any units with a
serial number prior to DC3645 are eligible for the update, according to
what I read on AudioCircle. Modification is free excluding shipping
charges.
Mine was the first DAC that got upgraded:)

You are above the threshold, so your DAC comes with the upgrade already
installed. I hope you are enjoying your DAC with your SB3 as much as I

Don't sell your FM tuner - particularly a good one! That would result in

Of course, I could be mistaken in all this:)
If the VU meters are pegged, then there is a good chance the file is
clipping against full scale, and the DAC is attempting to put out DC.

Maybe we have a solution already in sox. Maybe it can be used as a
low-pass filter and resampler. I am reading the rather long man sox(1)

Sox is already part of the Slimserver distribution to handle ogg. Maybe
it can do this too.

read elsewhere on this forum that you cannot stream 88.2 KHz to
the transporter, and in that case you should upconvert your files to 96
