I actually haven't tried that comparison yet. I only tried controlling Roon from my laptop in another room on my non-Taiko audio network, and it worked just fine.
Later this afternoon or evening I'll give that a try. And actually listen to it when I do!
Last night I decided that with about 125 hours of burn-in with my load resistors in the DCD Default, Alternate 1 and Alternate 2 power outlets it was time to shift the Taiko router and switch from the DCD Unfiltered power outlets to some other combination(s). I initially planned on doing this over several days to allow myself to get used to the different sonic presentations as well as doing some shifting back and forth between Roon and XDMS.
It turns out I needn't have been so conservative -- the Taiko DCD filters are distinctive enough that it was quick work to run through the various combinations and decide on my preferences for both Roon and XDMS:
Roon: DCD Alternate 1 > Taiko router, DCD Default > Taiko switch
XDMS: DCD Alternate 2 > Taiko router, DCD Default > Taiko switch
The above to my ears gives me the best combination of top end sparkle and overall tonal saturation and richness with most music.
Using Alternate 1 to power the Taiko router for XDMS is just a little too incisive and slightly forward, while Alternate 2 powering the router for Roon loses that top end articulation and overall is a touch too dark for my taste.
Alternate 1 to the router for Roon is quite good in terms of balance between body and sparkle, although I will say that Alternate 2 to the router for Roon is nice to have for recordings that might be a little hot and forward.
Default > router, Default > switch seems a little threadbare and thin with Roon, and very thin when XDMS is used. Likewise, Alternate 1 > router, Default > switch with XDMS sounds thinner and less tonally saturated than my preferred Alternate 2 > router.
I quickly ran through the various filter combinations, keeping Default > router and various filters > switch, and while some of them were pleasant they all pale in comparison to my preferred selections. Additionally, the magnitude of filter effect seems diminished with Alternate 1 or 2 on the Taiko switch, perhaps because of the lower current draw of the switch.
Finally, I found my overall preference for listening in terms of overall sound quality, has shifted back to XDMS with Alternate 2 powering the router. Roon, with Alternate 1 powering the router is not far behind and is still quite a bit better than I ever remember hearing it. Roon is very pleasurable to listen with and if I wish to play music that benefits from gapless playback or has a file size greater than 1.5 GB, or just want to kick back and let Roon Radio do its thing, it more than fills the bill.
(Edited to add): I also need to emphasize that the above comparative rankings are all still better than not having the Taiko router in use, regardless of DCD filter selection.
The Taiko router in combination with the DC power distributor is undeniably expensive and questions of value for dollar, Euro or pound sterling are very much a personal decision. However, hearing what the router and power distributor do for music I am unwilling to go back.
Kudos Emile and Taiko Audio!
