Do you build anything for your high fidelity system? If so, what do you make?

Lol long list. The stereo room in the last two homes the current one has 5/8 OSB then a layer of 5/8 fire rated drywall. Six dedicated powerlines with the wire crossed over it self so nothing runs parallel. All the wires the same length. The wall behind the speaker has a slight upwards angle the front corners of the room are angles off as well the ceiling rises a bit for the first eight feet. Stands under speakers. Diffusion panels bass traps absorption panels. Equipment stands furutech receptacle s put in power cords assembly. Amp stands arial mounting bracket. Lp holder  cd  cases. 78 case. Wall mount turntable shelf. Lol that's just the shortlist. As far as why i believe dense wood makes the best equipment stand that being said I make them out of thick slabs of either rosewood or purple heart. Also I have used walnut and bamboo planks in secondary system s. And of. Of course monetary reasons as well. Cheaper to make than to buy the ones built in lessor material. The base traps I made so I could vary the amount of suction they have so they are tunable. Signs telling people not to touch LoL. Spikes for stands as well.

i too used the hifiberry hat.  I think DAC+.  I see they have a new version out, wondering if it’s worth an upgrade?  As for Volumio, I use the free version.

I have built a few racks, some sound absorbing panels, and a long time ago, I built everything Hafler sold and I still have my Dynaco Stereo 400 amp. I also built some speakers and 6 subwoofers.

Speaking of Dynaco units, I have the ST150 that was personally built by the person who wrote the very first technical article in the very first issue of the JAES, January 1952. (Journal of the Audio Engineering Society). One of those accidents of fate, where you see an advert and you answer it. And then run into this given person....

Years ago, I made a 6 shelf equipment stand using oak plywood (from Lowe's) and applied edging, stained it many times, applied some Urethane clear coat. Used 6-foot long black anodized threaded rods (McMaster Carr), wide stainless steel washers, nuts, and a rubber washer underneath them at each joint.  Added casters (need larger ones now). In the rear I added some PVC conduit to route the cables to keep it looking "neat" for WAF.   If I had to do it over, I'd probably go for a 4-foot or 5-foot tall one instead. 

Just wanted it to be on casters for easy access to the rear for cable hookups/changes and for cleaning ease.
