Linear Power Supply Recommendations!
While I realize linear power supplies share the same basic principle—using a transformer to step down voltage, rectification to convert AC to DC, and regulation to maintain a steady output….there are several factors that ultimately differentiate their performance in a specific application.
Did you find one particular LPS performed better than the others? I am looking for a dual output 12V / 3A power supply to power my Telegartner Opt Bridge 1000M.
Ferrum HYPSOS Dual Output with its ‘Sweet Spot Tuning’ has caught my attention. Any users out here that is currently using this LPS?
+1 for Teddy Pardo dual power supply. https://teddypardo.com/product/dual-outlet-power-supply-custom-version/ I am using one with Bluesound Node N130 and Chord DAC to positive effect. I have also had success using MCRU and Swagman Labs PS, but not sure they offer a dual supply. kn |
Just received LHY (Jay’s Audio) LPS80VA dual output 12V/5A Linear Power Supply. Going to break-in for next 5-6 weeks and then compare with stock wall warts came with my Opti Bridge. If I hear improvements, then I will venture into comparing LHY with other LPS recommendations in the thread. Uptone JS-2 appears to be most versatile LPS with on the fly voltage adjustments and good long term investment. |
@lalitk I would be interesting to see a direct lps comparison, love my JS-2.
Forgot to mention JCAT Optimo lps, very nice quality lps, I use the Optimo ATX with my custom server.
For anyone using lps with various components, DC cables also important. I've built and or used a variety over the years, best have been Mundorf Silver/Gold wire with Oyaide connectors.

JCAT Optimo ATX is a serious piece of gear for a custom server, definitely not your average LPS solution. I used to own Optimo Duo 3, it was paired with Telegartner Gold M12 Ethernet Switch. When I added Telegartner Opti Bridge 1000M in my system, the M12 switch kinda became redundant because Opti Bridge on its own does a fabulous job of not only blocking noise gremlins but also renders much of M12 Gold Switch virtues. I believe in Less is More…so Opti Bridge 1000M (ahead of my streamer) with a good LPS appears to be best way forward. I just ordered a pair of FTA Metis LAN cables to try it out. They will go head to head with Telegartner MFP8 IE GOLD LAN cables. A direct LPS comparison would be interesting, especially between the JS-2 and maybe something like the Paul Hynes SR4/SR7 or Farad Super3. Each has its own design philosophy, from regulation to component selection. And you’re re absolutely right about DC cables. A quality LPS is only as good as the cables feeding the components. The LHY LPS supplied with decent quality DC cables but they are certainly not in same league as Mundorf Silver/Gold wire with Oyaide connectors. I believe Mundorf Silver/Gold wire known to have a pure, detailed, and revealing sound much like my all time favorite - JCAT Signature LAN Cable GOLD cable. Have you experimented with shielded vs. unshielded DC cables? Some setups seem to benefit from shielding, while others sound more open without it. |
