Ifi Spdif purifier

^^^^ You selectively left out an important part of the review regarding the comparison with and without an LPS:
"I should note that these are not audible problems as the levels are quite low. Just lack of good engineering and system design."

Nonetheless, still curious to know which LPS gave "astonishing" difference in the sound quality.

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