My Heed Obelisk PRE/PS/PX stereo amp drove HE-6 really really well, but guess it´s not the answer your are looking for .
I got a mail from "Blue Coast Music" with offers on some nice relaxing jazz music (in DSD I presume ??), but not sure which format to buy for the Vega. Can it play both DFF 2.8Mhz and DSF 2.8Mhz, can´t find any info in manual. So I ask here first before I spam Auralic.
Auralic Vega supports DSD64 and DSD128, that's the sampling rate format, the DSF/DFF files are just containers.
So yes, it will play it no problem.
