Replace wall wart to Simaudio LP3

The power supply to a phono stage doesn't have to handle big fluctuations in voltage and power draw

I know a few designers who would strongly disagree with that. ;-)

It is not worth spending $700 to replace a wall-wart. As was mentioned to you on AA, look at plugging in a battery supply. You can match the input connector down at Radio Shack to make up a cable. Most of the jump start batteries I mentioned come with a DC accessory jack and a cable. Might set you back $50 and will give all of the benefits you are seeking.

Right, why not extract maximum performance from a basically very good piece? Just might be a little expensive in this case.
My speaker cables were more expensive than my speakers, both new and used.

I have a Little Pinkie for my V-DAC and it makes a BIG difference; I recommend them enthusiastically.

Hah, my V-DAC cost $299, the LP around $200, the Transparent Reference digital cable lists for $1500 and the Oyaide GPX PC for $500. But it sounds extremely good together and that is the idea , isn't it?

The Wellborne Labs PSU I bought used from this site (Thanks Marc!) arrived yesterday in mint condition as described. The DC cord came with the same 2.1 mm male connector my Simaudio LP3 needed. Warmed up the trusty ARC VS110 and AudioPrism Mantissa pre and settled in for a listen. Immediately the improvement was readily apparent. With the wall wart I was getting some overload distortion on loud dynamics. Gone. With the wall wart the overall sound was very "hi-fi"-contrived and crude. The PSU eliminated that and replaced the hi-fi sound with a relaxed natural sounding timbre. The soundstage filled in and is quite wide-wider than it is with my more expensive LP5.3! My only nit right now is that the sound also darkened a bit-and I do miss the highs. I may need to play with capacitance a bit. Or maybe the LP3 just needs further break-in. For anybody out there with a phonostage using a cheap wall wart, I highly recommnend you look into a linear PSU. Particularly if you have the Simaudio LP3.
