Simaudio's new power supply for LP 5.3

Pretty much all of what Todd noticed, but I had no loss of deep bass. I also noticed a much bigger overall sound, and multiple vocals sound much more defined than before. I have around 100 hours on mine and have no intention of returning it.

Probably the bass is just tighter now, no loss of "slam"

I guess i would have to take back the statement about losing bass impact. When i installed the power supply i changed power cables to a cheap cryo'd cable. This change of cable caused the reduction in bass impact not the PSX 5.3 power supply. I have now returned to the original cable supplied with the 5.3 phono stage and my bass impact is back .
I hope to try a good high quality after market power cable in the future along with a PS Audio Premier power plant , hopefully i will see more improvements.

With the new power supply, the LP5.3 becomes a $2750 phono stage. I own one (without the power supply) and think it's a definite winner at $1500, but wonder if it remains competitive at close to $3K.

thanks for all of the insights - very helpful. I guess Drubin pretty much hit the nail on the head, though, as far as summing up my question.
