I actually joined back in 2013 because of a piece of used gear for sale and then promptly forgot about the forum!
My current interest lie in learning more about room treatment and DSP correction, as well as digital distributed audio (via Roon) due to moving to a new to us house this year. Once I get that under control I want to try my hand at building some speakers and experimenting on that side of things. I've got LXmini and folded horns on my to do list. Audio consumes my winter half of the year because cars/racing consumes my April-October.
