I’ve been experiencing this issue occasionally.
When I start playing DSF files, both per se or transitioning from playing a PCM file previously, the stream on Lightning DS for the Auralic Aries to the Direct Stream Sr via USB says DSD. However, the DoP signal doesn’t come on at the Direct Stream Sr (it says PCM) and I get loud hisses and crackles which is probably potentially speaker damaging until I turn the volume down.
Restarting both the Auralic Aries and the Direct Stream Sr will solve things. Sometimes I just need to restart it once, other times more than once. This is annoying.
I also use an Uptone ISO Regen powered buy an LPS 1. At first i thought it may be that so I disconnected and reconnected both the power from the LPS 1, as well as the ISO Regen, separately. However, the stream was still noise and read PCM on the DS Sr display.
Has anyone also experienced this issue?
