You can order an Audiophilleo1 Special Edition for an additional $150. The Audiophilleo1 SE supports up to 384 Khz SPDIF output as well as DSD128 over the DoP protocol. The Audiophilleo1 SE is one of a few SPDIF sources in the world with 384 Khz and DSD128/DoP support. Note that existing units cannot be upgraded to SE. Just go to the buy page and select the Audiophilleo1 SE!
Cutsomers have had very good results with the Chord Hugo DAC which accepts DSD128 and PCM 384Khz via the SPDIF input from the SE.
