Custom Power Supply for 6v DC Motor

Acopian is a specialist in quality power supplies. They have a lot of choices. An appropriate Gold Box model would very probably cost less than you say you're ready to pay.

My very humble experience in upgrading power supplies and connections suggests that it would be wrong to neglect the quality of the cable which connects the PS to the equipment.

For example, a shielded and (perhaps I should blush here, it does seem like overkill) cryo-treated cable sounded as clean as a 12V battery when used to connect an overbuilt regulated supply to my Apogee Mini-DAC. In comparison, a cable made up of scrap Radio Shack 18ga speaker wire and the same connectors sounded gritty and edgy.

Hicham, I'm not sure I understand your question. May I suggest you click on my link to Acopian and look around? You can enter an output voltage in the search field on the home page and find all the supplies they can make with that characteristic.

If you're wondering about input and output connections, though, you'll probably note, as I did, that the supplies come with screw terminal strips. For audio use, you'd be wise to plan on building your Acopian supply into an enclosure with connectors or captive wiring.

Hi Hicham. Whether the effort is worth it or not depends on how happy you are with what you had before. I hope you'll have a chance to post your results.

My own experience with aftermarket regulated supplies is limited to my Apogee Mini-DAC. I had originally replaced the stock OEM switching PS with a SLA battery but was having trouble remembering to switch off. I sent 2 batteries to recycling and then found an appropriate supply on eBay. My impression is it works as well as the battery.
