I guess I'll go first. I received the TeraDak power supply today and played with it for 3 hours or so. The first thing to note is that it works as it should. That's more than can be said for the battery I ordered for the LSA when I first got it years ago. That died within minutes.
The unit comes well packed and looks decent enough. Mine came with 3 wood isolation cones and corresponding supporting wood disks. That was either a mistake or a surprise New Year's gift, because I didn't order them. The cones are quite nice so I stuck them on the unit with some blu-tac. It doesn't come with a power cord so I used one that was just ready to hand.
The second thing to note is the retina destroying red indicator light on the front panel. Damn that thing is bright! That thing needs to be covered up. I left the unit powered up but unused for about an hour as I acclimated to the sound of the LSA with wallwart. When I switched over there seemed to be a significant attenuation of volume. I checked with my trusty radio shack db meter and, as far as it can detect, there was no change. Puzzled, I continued to a/b the two power supplies for the next two hours. Looking back, I believe the sense of volume attenuation was due to the decrease in distortions caused by the wallwart. The teradak smoothed out distorted peaks and thus gave the appearance of being softer in volume. It gave me the desire to turn up the volume. Another thing I noted was an increase in transparency. This was evidenced by how much more clearly enunciated were the words of songs. There were possibly other changes as well, e.g. in dynamics and soundstaging, but I didn't have a chance to fully explore those.
Obviously, a couple of hours is insufficient to draw any definite conclusions. Nevertheless, I'd be surprised if someone said they couldn't hear the difference between the teradak and the wallwart. Unlike with reports involving battery supply/wallwart comparisons, the differences noted here are not at all subtle. And I am not in any way a power cord guy. My few forays into after market power cords have ended in disappointment.
For $60 this thing is a no brainer in my book, if only to mess around with a new toy. I believe it improves on the already stellar sound I was getting, so it is for me better than just a new toy. YMMV.
Needless to say, I have no affiliation with the Teradak's maker.
