And I'm glad I did: I bought it
I purchased the LPS25VA as the first linear power supply for my audio system. So, I wasn't sure what to expect but I wanted to give it a try.
And I'm glad I did: I bought it to power to my Musical Surroundings Phonomena II phono preamp, which amplifies the signal of a Nagaoka MP-110 cartridge on my Rega Planar One.
I don't think the sound signature of the cartridge was affected, but from the preamp I do hear a smoother treble, darker backgrounds and a lot more precise spatial image all over a wider soundstage. After this purchase I'll delay upgrading my cartridge for a long time and I'll consider instead to get a similar PSU for my digital sources.
