Dead Uptone Audio LPS 1

Hi,

My LPS1 stopped working. I was using it with the ISO Regen, into my Ayre QB9 Twenty DAC. Even though I was told that the ISO Regen won’t do anything to improve the sound of my Ayre QB9 Twenty, I happen to prefer it with. So I plugged the ISO Regen into a dual rail TeraDak LPS. I do notice a slightly different sound characteristic via headphones. I appreciate having a power button on the TeraDak so that I can work on my files from my streamer without the DAC powered on. But should I be looking for a better LPS? The ISO Regen is so small that I can hold it between my thumb and my middle finger and rated at 6-8 volts DC. Anyway, I realize this isn’t the most engaging thread but any thoughts or advice is appreciated as always.
