Ok... For a start I would not believe ANYTHING on computeraudiophile.com.
There is a LOT of complete bullshit around DSD.
There are NO timing errors with PCM! It's a band limited signal!

Here are some bits from other posts I have made before:

DSD will not, cannot, improve the sound quality.
Here are 3 previous posts of mine on the topic:

Other posts in those threads will also be of value to you. There will be more on DSD from others who are probably better qualified, I only pointed to a few.

A DSD stream cannot be modified at all, so you need a preamp if you want to remain in DSD land. If you want to modify it, then it must be converted to PCM, even for volume change (amplitude multiplication).
I would suggest that DSD is unnecessary and it's full of audiophile BS. High resolution PCM is
at least as good, and without the ultrasonic noise-shaping issues, see

DSD to PCM conversion is completely transparent, see
https://archimago.blogspot.com/2015/04/analysis-dsd-decoders-2015-windows-mac.html So if you don't mind going to PCM then you can use a digital volume control.

I did do a blind test in a studio with the Korg MR-1000 DSD recorder when it came out, signal split after the mic preamps and sent to the Korg recorder and also to Avid Protools PCM converters at 24bit 96KHz. Level matched on playback, there was no audible difference between the DSD and PCM version.
Given the aggressive noise shaping required by DSD to make it work, and the fact that it cannot be edited or processed (even volume change is impossible) unless converted to PCM, I can see no value in DSD at all now. When DSD was developed PCM was stuck at 16bits and 48 KHz and perhaps it had an audible (or archival) advantage over that format of PCM, but today we routinely have 24bit 96KHz PCM which has none of the disadvantages of DSD, it has more resolution than we can hear and it can be edited and processed easily.
