@Energy thanks for all the posts about DSD transcoding. I did up to DSD512 in the past with an iDSD Micro, Foobar2000, and i7 4765T (with c-states, turbo, and hyperthreading disabled for less jitter) at about 40% usage. Also have an 8-core AMD FX machine but sounds like neither cpu has enough cores/cache to max out HQPlayer's settings. Haven't tried HQplayer yet but your posts got me thinking about my future upgrade to a Holo Audio DAC. Was also planning to get the Pink Faun i2S Bridge and avoid USB altogether but afaik that card doesn't do DSD. Assuming I got a DSD Cyan (or Spring), do you think DSD512 over USB/i2s via an SU-1 or Matrix X-Spdif 2 would perform better than PCM over a direct i2s to i2s connection?
