Time to put together a digital setup. I like my old DAC and I imagine that I'll be using a raspberry pi as the source. I'll need a HDMI-to-optical (or coax) converter to get them together.
Are all converters the same, or is there anything to be aware of? Cheap chhinese off ebay is always the first place I look
edit: for what it's worth, I use a non-oversampling dac
