Thoughts on up-sampling
Thought I would run this past everyone before I try it. I seem to prefer the smoother nature of up-sampling thru my player and Lumin. Would it be best to up-sample with the lumin (K01x up-sampling off), or use it set to native and up-sample with the K01x DAC?

I've always believed upsampling should be done closest to the dac. However, I own a k01x and feel that no upsampling, or maybe only 2x, sounds best.
You should just try both and trust your ears [emoji106] |

I have a K-03X and listen to mostly classical music, some Jazz. I've read what others (including reviewers) like and have experimented quite a bit. I generally like 4Fs upconversion with the SDLY1 filter. DSD filter off for SACD playback.

So far I tend to agree with both of you. A small dose (2x or 4x) of up-sampling and use of a filter depending on the material.

DCS Rossini. Depends on the recording. For good ones I don’t like the upsampling. But I like the option since it seems to take the edge off more super compressed rock / pop.

With my Vivaldi I usually go with either DSD or DXD. I have left it on DSD for the last few months.

I have an Ayon CD5S with quad R2R PCM1704K chips. The DAC has the ability to run native 16/44.1 from the CD transport and play up to 24/192 on the SPDIF inputs. It can also upsample the 16/44.1 to 24/192
I also managed to snag some Linn files a while ago and they were able to produce the same track/albums in 16/44.1, 24/96 and 24/192 I found that upsampling the 16/44.1 did indeed produce a sound not dissimilar to the 24/96/192 versions, in particular a smoothness to the sound. But that may or may not be too everyone's liking. In some cases, I prefer the edginess of the original 16/44.1 but that may be a filtering artefact.

What I’ve found is that any difference in audio quality with upsampling+interpolation is due to the digital filters employed in the D/A converter.
I think we are now listening to differences in digital filters more than any other differences in our digital playback systems.

The biggest impact is it moves the alias frequencies far outside the audio band, allowing for simpler digital and analog reconstruction filters. I think that is what we hear when we over sample - the filters used by the DAC, not the oversampling process itself. Tom
