EverSolo DMP-A8 with Denafrips Pontus 15th, both have i2S

@mbolek makes a fair point, a ddc is often used to clean up USB signals.  That is why I have one as I stream using a MacBook Pro.  Given that your streamer has I2s output you may not gain much with the ddc.  You would be getting s much better clock with the ddc but then using a different output from the streamer which would involve conversions to I2s format when outputting from the ddc to the dac.  The clock might be worth the effort though, timing is significant in the digital world.

Thanks, I'm looking forward to trying everything out. I don't have a problem purchasing a Denafrips DDC if it comes down to it. I realize this is a hobby, and striving for a great sound.

mbolek, I'm glad to hear you have an A8, and i2S is working well with your Harmony. I'm hoping to find a user with A8 and Pontus to ask what Pontus i2S settings they use? I thought I heard one person say, when configuring,  1x on 4x on?

In looking at the specs for both DMP-A8 and Pontus 15th, I think the new Pontus 15th has the same Fentosecond clock as the DMP-A8. I will try evaluating them both ways, USB vs i2S. If I can’t tell a difference, is there a theoretical idea that would favor one or the other? I would think i2S would be the way to proceed if I can’t hear a difference?

If they both sound the same to you then it doesn’t really matter but I would stick with I2S.  The USB connection should utilize the DACs clock instead of the A8 so any difference you hear could be attributable to that as well.

Just so I understand further, feeding the Pontus with USB vs i2S, this only affects which device controls the clock (with USB, the Pontus controls the clock, with i2S the A8 controls the clock). And, to further understand, In either way, the Pontus DAC is utilized. Please correct me if I’m wrong.
