Julien, that’s how I had mine setup. Dedicated stereo output is significantly better. This chip is also routed to the headphone output so the headphone output is stellar too.

Did a quick A/B comparison on Hi-Res audio and they sounded different indeed.

Stereo output has more.... Juice? Power? Clarity?

I could tell which output was used (listening to The Jacksons' Triumph album 24bit/96KHz over the OPPO USB DAC) in blind test with a friend.

So, yes, clearly there is a difference!

As explained on my long post, ess chipset is an fpga (and i2s receiver) with added 8 dac and built in current/voltage converter. Those 8 dacs are configured to be two banks of 4 in parallel on the stereo output and 8 banks of 1 on the 7.1 output. Every time you double the dacs in parallel you gain 3db s/n ratio. 4 dacs per ch is 6db improvement and should be audible as you verified.

A most interesting dac would be 1 ess dac chip per channel. That way all 8 dacs in parallel for a total of 16. Or even better 2 ess dacs per channel. I guess the sweet spot is 4 dacs per channel as no one so far used multi ess dacs per channel.
