Hi Edward … after some investigation about the requirments my idea is on hold due to lack in my technical skills. The possibility to directly connect a NAA via I2S directly on DAC requires additional circuitry with galvanic isolation and a reclock … and this is out of my knowledge. I'm still convinced of beauty of the idea due to it's simplicity and the fact that a physical cd transport use I2S and not USB to dialogue with the dac …
Today I got a message in relation to another user that's looking at the same solution and I already contacted it.
In the meantime, I'm working to install Linux and NAA software on a new micro unit … this one … totally different beast than BeagleBone. It's a very minimal unit, very low EMI emission and noise .. I hope to have it working connected to JLsouds dac in few days.
Edward (aka EuroDriver) here in Monaco. I was wondering how your DSD DAC iwth HQ Player NAA front end was coming along ?
