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

I built my power amp using the Neurochrome 686 units using a 1000 VA medical grade transformer and 4 x 51,000uF 100V 18,000 hrs at 85C of filter capacitance using 160 amp bridge rectifiers, which has about 0.6 volts fwd V drop so that their heat generation was virtually non existent even at very high currents.

Since Orchard audio has recently introduced v3 of his Starkrimson Ultra class D GaN amplifiers, and since those also work with only +/- 36 volts DC (exactly the same voltage the Neurochromes were working with), I am planning on changing the Neurochromes with those to see how much difference in the sound and/or heat generation there is.

Stay tuned.

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....
