What have you been working on in 2020?

I built a touch screen Raspberry Pi 4 with a Hifiberry Dac. Really enjoying Tidal. Also built 2 iron pipe audio racks with butcher block shelves. The shelves are a work in progress. Built several DIY cables with mixed results. Rebuilt several amps with higher quality capacitors and speaker bindings- also cooked a Vintage Nikko amp I have had for decades somehow😖

Erik, I’m trying to figure out if it would be worthwhile to upgrade power cords on some of my components. Doesn’t really make any sense to me to do so, but that doesn’t mean it might not make for some improvement for reasons I’m unaware of. I thought I might start with upgrading the stock cord on my Luxman 507uX MkII integrated amp first. I read somewhere here you upgraded the power cord on your Luxmann integrated. Did you notice any improvements in sound after you did so?

Built two pure Class A power amps, built a state of the art tube hybrid power amp, redesigned our preamp making it sound even better than before, experimented with capacitors and resistors in critical places.  Repaired at least 50 pieces of audio equipment.  Other than that read to much BS like this on Audiogon.

My projects:
1. Tired to build a high quality DH Labs and Wattgate power cable. I need to work on that. It’s not quite right. 2. Added two REL T/9i subs to my Maggie 1.7i system. What a humongous improvement! Also added another (1) REL T/9i I got for a steal on my Magico A3 system. Not as big an improvement. But not bad. Those A3 handle bass pretty well already.
3.  Discovering lots of new (to me) jazz artists on Roon. If you like jazz, I have discovered a plethora of great Israeli jazz artists. Who knew?! Wow. 

Spent most of the last 6 months working in the hospital.  The rest of the time I have been setting up room changes/treatments. Much better with room size change and new flooring installation.  Also spent a lot of time trying to understand how to optimally set up streaming with my system but just don't get it yet.  Everything I read discusses hardware/software with a lot of numbers and letters that seem completely foreign to me.  I just don't get it yet.  Not gonna give up however.
