I have both adapters from Voodoo. Not sure if my mind playing tricks on me but the lesser $89 did perform less than the $200 one.
Note 1: I only left the $89 in system for few days and couldn’t bare it so it’s has never returned to my system. I seem to be more happy with the more expensive $200 one. Both have life time warranty. The $200 one I bought from eBay certainly went bad on me. I called Voodoo in hope they could repair- they sent out a new one the next day all free of charge.
Note 2: same power cord, I later swapped out with new 20A plug and I thought music flows even better.
