Ifi Spdif purifier

Sorry, I didn't see your questions until the @ notification was used.

I'm using a Swagman Labs Signature LPS, recommend by a couple of members. $280 for all premium parts built to order and a major upgrade in sound. I had good contact with them throughout the order and delivery process.

The iFi takes 5 volts. If it was mistakenly fed 12 volts, would it likely blow?

I agree with the comments about the iFi needing a better LPS. I had an old Core Audio Technology Kora around and that helped a lot, but a Paul Hynes SR4 is even better.

definitely

What the review doesn't mention is how the S/PDIF coax cable can affect jitter and the overall SQ. 
In my system using a PS Audio PWT and Audio Note NOS dac, the iFi plus LPS made a noticeable improvement. Music's more organic, spacious, has more weight, lower noise floor. I was using a variety of coax cables, always searching for one that would help achieve that analogue-like presentation.
I'm now using a High Fidelity CT-2 SPDIF and the improvement is astonishing. With this cable the sonic effect of the iFi is negligible. 

As a reminder, in the review the iFi was tested using a SMPS wall-wart. Not really a fair test for use in a high-end system. Even the designer of the Synchromesh recommends the use of a LPS.

lowrider57, did you special order the Swagman LPS with the mini USB to fit the iFi or had to cut&splice the cord?
