I wanted to make a volume control-five pieces came out. I worked without a lathe, so the geometry is not perfect. Four handles still need to be finalized, and the fifth immediately fit perfectly. Made of oak and cherry. Photo under the spoiler.

Mine stays just a bit above room temperature, regardless of load.

Mine got only hot the first couple of times I used it. Now it doesn't get warmer than every other A/B amp that I owned.

Meaning you notice it is on, but nothing to worry about.

So far really impressed with the buildquality. Soundquality. if Singxer ever made A/B loudspeaker amps I would seriously consider getting one.

I just wanted to drop by and give some totally unsolicited advice real quick. If someone has a 6x0 go ahead and try it on high gain. I've been using my new Bori for the last 3 weeks and just wanted to try my 580 and 650 and compare, but they sounded HORRIBLE to me (very, very unengaging, no dynamics at all) and it turns out I had it on low gain. I switched back to high gained like I used to have it and all of a sudden everything came alive.

Not everyone will prefer it but if you have a 6x0 and usually listen to low gain try high gain, it's much more engaging. Don't forget to switch it like me, it almost made me sell my 580 cause I thought they sounded so bad LOL.

Agreed, always use high gain with my 600. I also use it w my M1ST which really doesn't need it but sounds phenomenal also

I may be in the minority, but I prefer the softer sound of low gain.

You all are otherwise right though: right around the 300 hour mark, mine both mellowed out and opened up. Juicy midrange, delicate highs, and a wide open soundstage. My closed-back DCA Ether CX now sound way more open than a closed-back design should sound. Damn.
