Innuos Pulse DSD Mode Questions

[RonLilley]

I just received my Pulse and have been advised to select USB Latency Mode "Low" and do hear a subtle difference in SQ from my Hegel H390 DAC (internal).

My question here regards DSD MODE settings for the Pulse H390 pairing. Should I select 1) NO DSD Support, 2) DSD over PCM, or 3) Native DSD to ensure best SQ? I am using Qobuz (Studio) as my streaming source.

Complete system is:

Shunyata Theta XC power > AQ Niagara 3000 > Shunyata Theta NR power cord > Hegel H390
AQ Niagara 3000 > Shunyata Theta NR power cord > Innuos Pulse > Audience Studio One USB > Hegel H390 USB >
Audience Studio One speaker cable > Audio Physic Classic 25 speakers

Set it to Native DSD and try to play a DSD file. If it doesn't work, set it to DSD over PCM (DOP) and you should be good.

Thanks so much, I'll give that a try.

@RonLilley if you look in the manual for the H390 it looks like it only supports DSD in DoP format.

"H390 supports DSD64,DSD128,DSD256
via DoP"

Thanks!
I've set it to DSD over PCM and all is well!
