@Paul Staples . Remember what we agreed on ? Less conversions is always better for music right ? Not only in computing, data transfer, but also Mechanical designs and so on for many other things in life...he’ll! Even a passed on messages or conversion, the less conversions is always the better.
So, why NVME and PCIE with Direct I2S is ideal ? Check out these pictures and let it sink in for a bit. Also, this is not only technically speaking or theoretically speaking....I compared SSD and NVME, there are vast differences
Be known that Pinkfaun also have USB bridge with upgraded OCXO option, if that is the way you choose. Just remember, DAC communicate by I2S
