Well I finally have nailed down my "no music from Fidelia" to Fidelia itself for sure.
I downloaded two other music players, Audiivanna Plus and Clementine and both provide 192/24 playback through the Mindsp new USBstreamer board built into our Fet Valve DAC flawlessly.
The problem is a Fidelia issue. I hope they fix it soon as I like the interface better than the others.
Anyway, the good thing is that we have confirmed that the new USBstreamer board works great and we will be able to now offer it as a transparent USB interface to our Vision EC DAC, Vision Hybrid DAC, and Fet Valve DAC. When this option is selected, the Coax 2 input now becomes a USB input.
We don't have a final price set yet, but it should be no higher than $200. Another nice thing about the USBstreamer board is that it comes with free downloadable software that allows high bit rate performance with a PC computer. No extra software is needed with a current Mac computer.
Thanks you guys for your help with this issue.
