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.
