Optimum config for Lumin u1 MIni

Upsampling is better than CDs? 

Wowee.

I would connect the Lumin direct to the Sonic Frontiers , you can upsample or downsample in the Lumin U1 mini there's no need to use the D2D. 

Connect direct to SF, the jitter reduction topology in Assemblage is obsolete and the upsampling is doing nothing for you. In this case less is more.

Upsampling is better than CDs? Wowee.

For @sns:

Interesting comment.  Can you elaborate?  Are you saying that it's obsolete because jitter has become a thing of the past?  Or that the D2D's jitter reduction implementation itself is obsolete? If the latter, does it matter as long as it still works?  Obviously I'm old school and the whole topic is way over my head.

FWIW, I'm not interested in streaming DSD downloads and Tidal/Qobuz only stream in PCM anyway.  Doesn't matter cause the SFD-2 can't do PCM anyway.  Then the only question is coaxial BNC or AES/EBU?  I've never settled on a clear winner but everyone has an opinion.

As for the rest looks Like I'll leave the D2D-1 out of the loop.  Thanks and cheers,

It only proves that passing thru the D2D sounds better to you. So do it and don’t bother asking for reinforcement.

I can variably upsample thru 2 different players. This is hardly noticeable to me. I only do it because I can. A good DDC or a good cable make more of an improvement.

klettermans,

Yes jitter is less of an issue in more recent DAC designs, but you obviously have this managed well with your existing D2D and DAC that incidentally still features one of the better analog sections around. 

Upsampling when appropriate, and playing higher resolution files is another matter.  This is where your new Lumin will excel, and it features a configurable control panel for upsampling, downsampling, and pass-through.

Your D2D allows you to disable its upsampling feature but retain jitter management and other noise filters.

Incidentally, some of Qobuz and Tidal music is sourced from original hi-res digital masters and streamed at 24/96, 24/192, etc.  Some can discern an audible difference in the better recordings. You might be able to allow passthrough for these without any upsampling.  

So as an option you might try configuring the Lumen to exclusively manage sample rates and feed the D2D for pass through.  But as addressed by Fuzztone, only you can determine whether any of this will be audibly significant.
