I think it was my set of 400i that you heard. Another thing you may consider is the grill mod. I did find that it gave what I interpreted as a bit more air... and some soundstage improvement as well.
Tell me more about the Gotham cable.
Normally I use the Canare star quad cable for low cost decent quality for my cable runs. The 400i stock cable is too short and I needed a longer cable. My Oppo Ha-1 was a bit straining to drive the HE400i using the 1/4 output with the stock cable. I also needed a 4-pin XLR balanced cable to allow my Oppo Ha-1 to drive the 400i to its fullness and also to my LD VI+. I brought my cable from Dyson Audio on Ebay. I use a piggy back adapter for my IFI Retro amp. The Gotham cable is thinner than the Canare cable and tangle a bit easier also. The Gotham cable is working out just fine. Since the 400i is a bit mellow it is a great match to the slightly brighter OPPO Ha-1. The soundstage is becoming very good and I do go back to my other headphones just to keep my vantage point on soundstage the same. I was with the stock cable was getting a bit of roughness in the upper midrange or lower treble as shown in this CSD plot. Now with the new cable the treble spike is less and cleaner.
