My impression from the Logitech site and this forum is that the Squeezebox Touch and Transporter can do 24/96k audio, but not higher. I see the MicroMega and Auraliti boxes that seem able to go to 176 and 192k, but they seem not to be on the market yet. Is there a Squeezebox-like product currently available that will do 176 and 192? In my view it doesn't have to be wireless.
No, not yet.
But I expect more 192/24 capabilities as more computers and DACs fully support USB 2.0 which can handle 192/24 files.
Currently only Apple's latest build of Snow Leopard 10.6.2 supports the full 2.0 codec. Windows 7 should support it soon.
In six months 96/24 will be the new 44.1/16 while 192/24 is the new 96/24 :)
