I ordered a single and dual board from Coffin on 7 May and received the boards 10 days later. They are exceptional well made. I built up the single supply board and it worked great; very stable and no oscillations. It made a big difference on my DAC.

Thank you Coffin!

each member from DIYAUDIO can ask for one sample PCB(dual or positive). Because the different voltage has different BOM, please tell me output voltage you need. Only 20pcs of samples for each reg.

Applyer only pays the registered airmail shipping fee 3.00USD.
