It’s time to pretty up the looks now that the internals are done. Here you can see the original black case. It’s dull and boring. The biggest problem with this cover is there is not enough ventilation to vent the heat from the rectifier tube. In summer the heat builds up and the DAC starts emitting a lot of heat induced noise which plays out to the system. I had to remove the cover whenever I used the DAC, a silly thing to do as this is a live 240V unit. The solution is to add more ventilation holes to the cover, and what better than to do that with words? Here is the cutting in action, with Don’s CNC machine.Starting to look better already! So the words sit on top of the rectifier tube, coupled with the existing vent holes from the bottom, the problem of heat induced noises is now solved.
