    Haven't heard anything further from the owner so I can't report anything here.

    I'm busy anyway with RMAF this weekend where an ISO-DAC can be heard in room 2014, Tower 2 innovation area - the AudioKinesis speaker room. Drop in & have a listen - it will be interesting

    Just my twopenny worth... and apologies if I am completely wrong.
    However i have been running a Mac mini with Audirvana on it into a valve DAC (built by Duncan/tubehunter as it happens).
    Anyway the machine asked me if I wanted to upgrade the operating system, which I naively did.
    Up to that point the DAC had played brilliantly through the optical out.
    Following the ‘upgade’ The optical out was no longer recognised. Seems to be something to do with the way that the latest macs work... apparently.
    Anyway because I bought the Mac mini second hand I can’t revert back to the older operating system.
    I gave up in the end. Sad really as it sounded excellent.
    Have no idea if you are facing the same issues Al, but thought it worth sharing the experience
    Cheers Steve

    Haven't heard back from Alex since the beginning of Oct when I diagnosed that the problem is probably that the DAC's firmware needs to be reset once the battery is allowed to fully deplete.
    I gave him the instructions on how to do this.

    Just to update this thread - AlCarmichael is sending me the Ciunas DAC to update the firmware or diagnose the problem.

    BTW, if anyone is interested, I've organised a tour of the ISO-DAC & ISO-PS on PFM but don't know if I'm allowed to start a thread on that?
