I have used mostly BMI for years now, but previously tried many others. the higher end stuff included Stealth Dreams, Elrod EPS's and Statements, NBS, Dream State, Siltech and Fusion. The list is very long otherwise, but suffice it to say I always came back to BMI. I didn't care much for the Whale Supreme, but the Orca series was really nice and the Hammerhead series amazing although I never heard the 4. The HH5 was so good, I bit the bullet and have 3 Oceanics, one of them Silver. Every BMI power cord I have sold has been met with incredible praise from the buyer....it's nice testimony. And, for me, they have represented surprisingly large system upgrades. The Oceanics are heads and shoulders above what I have ever had the pleasure of listening to in my system. BMI's cords make it so there is no guessing or wondering if there is an improvement in the sound of your system, it is in your face apparent that they show what a power cord can add. Try one of the earlier models out if you ever get a chance. Not many come around...more testimony!? Anyway, I hope you you get to check them out, it would be nice to hear what you think....or hear....
