I can't speak the the "Eden Series" from Maze Audio but I am trying out the "Ref 4 Krell Cryo" power cords in my system. I have 3 in place right now: 1) between my Bryston MPS2 power supply and my Bryston BIT-15 power conditioner, and 2) between the wall and my BIT-15 power conditioner. I have a 3rd that will go from either the wall to my Bryston 4B2 power amplifier or from the BIT-15 to my Bryston 4B2.
I have been listening intently in the evenings and trying to imagine if I can detect much sonic difference. I would say that there is a definite difference compared to the stock power cords. I do feel that the increase in detail is immediately noticeable but that with repeated listening things simmer down and the detail and the quietness and smoothness balance out better over time.
The woven construction with the brown jacketing, combined with the polished silver of the Krell plugs is pretty great looking. For what you pay, I am not disappointed. I don't have much experience with other aftermarket power cords, just my subjective recollection of changes in sound quality compared with stock.
