Afraid you are still missing the point I made earlier about the market.

The 'audio' market is fragmented. Some will use small iPlops and moble
phones and focus on highly compressed lossy formats. Others want good
results and use LPCM or formats like flac. The wish for good results and
LPCM 96/24 tend to go together. Would *anyone* want '96k/24bit mp3'? It is
almost a contradiction in terms so far as the audio markets are concerned.

Being able to use a 96k/24bit iso/asynch USB DAC isn't aimed at the "vast
majority". It would be for an influential (in 'fashion' and 'aspiration'
terms) group who tend to *prefer* the 'unusual' approach, and will spend
extra for it - once it is available and shown to work well.

And I find my Iyonix can play mp3 or flac OK. No hardware DSP in sight. So
I still find it hard to believe that no more modern RO hardware would cope.

There is a simply way for you back your assertion, though. Show us a RO
hardware system that can drive one of the iso/asynch USB DACs and I'll test
it.  :-)

Slainte,

Jim
