My first iFi product, the $50 iFi iPower had to be immediately sent back to the retailer because of poor manufacturing and/or QC. There was something rattling around inside of it. Perhaps it was a plastic piece that came lose or it could have been a metal screw. In any case I didn't want to chance having it cause damage to itself or to my gear. What a disappointment. It was promptly exchanged by the retailer for a new one but that experience (along with the iFi experience you shared) left a very bad impression with me of their products.
I still own the replacement iFi iPower (one of the many power sources recommended for the microRendu) but I hear no difference between it and a $10 wall wart I bought off Amazon.
Even though your Jameco LPS doesn't have stellar specs, most digital gear with their own onboard regulators don't need thousand dollar external LPS's. It's not like you're powering the high gain analog stages in a phono preamp. But audiophiles will be audiophiles and 'designer power supplies' are easy to tinker with and throw money at. ;-)
