Power conditioners and wall warts


Is there any point in plugging a wall wart into a power conditioner, other than surge protection? Could it be a negative thing to do?

Based on input here, I bought a Signature Edition Swagman LPS for my Project Tube Box DS phono preamp to replace the stock SPS.  I agree with lowrider, the Swagman is excellent.

I had tried another Chinese built LPS with the Project that I borrowed, and found that sounded bass heavy and dull, so went back to the stock power supply which was tipped up a bit from neutral, but it has good drive. The Swagman takes the Project and my enjoyment to and entirely different place, everything is better.  Ridiculously better.  A Very good deal in terms of the build quality and performance.  Can’t speak to the stock model, but the Signature Edition is great.

I previously replaced the SPS on my Arcam irDAC with an MCRUS LPS with great success.  I looked at the MCRUS supply for the Project preamp but souped up versions of that are twice as expensive as the upgraded Swagman, so thought I would try it.  Not disappointed.

Perhaps not surprisingly, getting the Project SPS out of my power strip makes the MCRUS/Arcam DAC sound better too.  I am using a Shunyata Venom PS8 power strip, Venom HC supply cable and Venom Defender power conditioner, and while this is extremely clean sounding, I am certain the isolation is not as significant as more sustainable conditioners.  I have all sources plugged into the Venom, amp and sub are plugged directly to wall.

Anyway, plus two for replacing stock SPS with aftermarket LPS.
