What have you been working on in 2020?

Parted ways with my legacy B&W + Rotel setup of 15 years to enter the world of seperates with a Schiit Saga+ and Vidar combo. 
I know it's sacrilegious around here, but I took a chance on a no-name phono preamp made in China with incredible results. In fact, after some tweaks, my vinyl setup officially sounds better than my digital setup. 

My last project for the rest of the year is to find new ways to enjoy my current setup without new tweaks or purchases. 

There are plenty of extant power cord discussions on Audiogon.  I would like to encourage those who want to engage that topic to start a new one or look for an old one so we can stay more broadly focused here.  Thank you. 

...the only power cords noted here should be spelled 'chords'....;)

"Good times, bad times, I know I've had my share...." *humming into the netherspace...*

Like lots of others I rekindled one of my oldest but dormant loves this year:
--got a cheap turntable (shout out to my buddy, Chris, for pushing me): this began it all in January
--realized my AVA dynamo pas III pre-amp phono stage was gone, got AVA vision Q, February (thank you, Frank)
--got a PS Audio P3 and a Monarchy 22B DAC from by brother (thank you, Eric!), February
--put in dedicated circuit, line, and PS Audio plug (myself), March
--Isoacoustic Gaias under my Abbys, March
--cones and carbon fiber pucks under everything else, except Isoacoutics under sources, March
--My old stereo 70 blew (still figuring out if I can fix and upgrade it); researched/stressed out about a new amp, picked a trade-in LTA ZOTL 10 (so happy! Mark was terrific), April
--made some isolation plinths out of marble and out of solid mahogany (that I found in the house when I moved in 20 years ago), May
--replaced AUs with 1961 Amperex 6085s (Brent Jesse) and ATs with 1962 Amperex 7062s (Andy at Vintage Audio): again much research/stress, but worth it, June
--Full HFT/FEQ treatment (thank you, Peter from Cable Co!), July
--replaced 30 year-old cables with SR Foundation (ditto, Peter), July
--ordered Audiokinesis Swarm (learned lots from Duke on this forum)
--ordered Townsend super tweeters 
 
Everything mentioned made a very noticeable improvement in SQ. Everyone was super generous with their knowledge and very helpful along the way. Except for Van Alstine, others turned me on to everything above, many on this forum.

Thank you (still plenty to do).

I am playing with multichannel + Roon.
Erik, can a Pi endpoint do multichannel USB output?
