10-Year old SMPS design still an excellent performer

I have been using the CONNEX ELECTRONIC Switch Mode power supply for almost 10 years [link]. Chose this power supply solely based on the theory that it would be a low noise, and suitable for audio applications.

You can purchase Connex SMPS directly from the manufacturer, but if you are in the US, purchasing from HIFIMEDIY may be a better option [link]
