MSB platinum DAC USB2

192kHz USB $1000
384kHz USB $1400

I just don't get the pricing.

I would suggest that you are looking at raw sample rate numbers and creating an imaginary and I might add irrelevant cost/sample-rate ratio.

This is not how R&D works. This is a proprietary implementation and is quite a bit more complex than what some others have been selling.

I have consistently found the MSB dacs (ladder dacs) to be far superior to most other dacs i have previewed regardless of cost.

Thanks for your response. Though no one reply to my question.

"This is a proprietary implementation and is quite a bit more complex than what some others have been selling."

Can you explain your statement or refer me to a link that explains why there implementation is more complex than others?

Implementation of asynchroneous USB can be done in different ways, but I fail to see why their implementation is at least 500% more costly than others.
