Lumin D2... Could it be a perceivable upgrade in sound quality?

[Martin_Kelly]

I asked Peter a similar question in relation to my A1. Both the A1 and the D2 share the same Wolfson DAC’s in common.
This is what Peter has to say on the matter:

Lumin A1 DSD Upsampling

A question here for Peter @wklie Hi Peter. I have read reports that the Wolfson WM8471 DAC’s in my A1 perform technically ‘better’ when processing DSD/DFF files, over PCM. Is this true, and in the A1 implementation of the WM8471, and putting purely sonic considerations aside. is there a technical advantage to setting the A1, or indeed Roon to upsample PCM to DSD by default, rather than native processing in PCM? Many thanks.
