I purchased an ESP Essence based on a review using the cord with the 8Ti. I found it used here, and paid a fair price for it. I am not sure that I can provide the same praise that the reviewer heaped on the combo, but I will say that it may provide some mid-bass improvement. The operative word in that previous statement is "may". The jury is still out on this issue. Whichever cord you do go with, you should be aware that the amp requires a 20 amp IEC. Best of luck.
My opinion, for what it's worth.
