What have you been working on in 2020?

This year with both of us working at home full time, I got a beyerdynamic A20 and DT770 headphones. So she can watch her TV in the family room while I bliss out in the living room.
I swapped out my speaker cables and most of my old interconnects from Monster for Marrow SP4 and MA4. (Only the long interconnects from pre to amp remain. Saving $$$ to replace those eventually)
When I installed the new cables I took everything out of the cabinet the system lives in and added isolation feet under all the components and rerouted all the cables to get the AC away from the interconnects.
Updated my cartridge from a Denon DL103R to a Hana EL. Now THAT'S what I'm talkin' about!
When I installed the new cartridge I retuned my Linn LP12 Valhalla and M&K/Rabco tonearm. That thing is a bear to get just right but when you do it's delightful. (Reminds me: I need a new battery)
And as always, I spent the entire year that I have a wife who loves the music (if not all the gear) as much as I do!
Cheers...

I’ve gone a bit in the opposite direction perhaps, somewhat counterintuitively I’ve found myself working more and with less free time in COVID times so I’ve gone the “time is money” route and invested in some expensive upgrades (speakers, amp, preamp, cables - only the DAC has survived) to get closer to “happily ever after” and not have to tweak and fuss so much. I have to say the plan has been a success and the system is sounding really wonderful. It was a lot of money but I’m happy with the returns.

(I did also get another rPi as a Roon endpoint but that was all of half an hour assembling and setting up. Pretty happy with how close to plug and play it is nowadays with Ropieee etc.)

I built a pair of Linkwitz LXMinis and made them completely voice-controlled.

Chain is Alexa/Amazon Music HD > DTS Play-Fi skill > Paradigm PW Link preamp > MiniDSP 2x4 HD > two stereo power amps > biamped LXMinis.

All equipment is plugged into an Amazon Smart Plug so turning it all on is voice-controlled with the command "Alexa, turn on stereo."

Can also stream wirelessly from PC using DTS Play-Fi.

Built a Pass Pearl phono preamp. I was mostly curious to see how much more is in my LPs, and it turns out there is indeed more in those grooves. I thought my Rogue Sphinx Phono stage was pretty darn good, and it is, but there’s just more through the Pearl. It also has more gain, 55 dB, than the Rogue and was being overloaded occasionally by my 5.5mV MM cart. So I switched to a LO Grado Timbre Opus3 (1mV) And very happy with the combo.

now adding LPs off Discogs.
