Here, I need to update/upgrade the power in my room - dedicated line from the panel to the system. And then probably a conditioner. And then better power cords. And better speaker cables (on the radar already) for the Harbeths. And some better stands under the Harbeths. And maybe a DAC for the computer. (Or not, as I was getting a bad speaker reflection from the computer monitor sitting on top of the rack, so I put the monitor on the floor. And I already turned off the computer as its near-silent operation wasn't quite silent enough. Maybe I'm not ready for this computer-audio thing quite yet?) And a little less absorption and a little more diffusion with the room treatments. And a better one-step "quick wash" for certain LPs rather than the usual 2-3 step deep clean.
And... and maybe I should "cool it" a while? (I basically did a whole new system in 2018.)
Actually, my system would be well served to remain as-is for 2019 and I should devote some effort and time in to getting my albums in to Discogs. I already got them all in one place and organized/sorted earlier this year; that's the next logical step, and one that's been lingering on my mind for some time.
