I'm pretty sure its the cable because depending on what I plug it into, the drivers either sound equal, unbalanced, or no sound from the left at all. When it does work, I don't have any distortion issues, I just have to turn the left channel way up--I suppose I could use it like that until the cord gets fixed, but I'm afraid its not good for the amp. Especially if the cord detaches the rest of the way the amp runs with no load on that channel.
I wouldn't buy another headphone just yet. If you just want another headphone that's different, but if you're looking to drop enough money to buy another mid-fi headphone just to play with your tube amp while you wait for your DT880 to be up and running, that money could have been better spent on the DT880 itself and/or cabling and/or more tubes and music which ultimately would be the better investment if you love the DT880 enough to have it for 10+ years as your only headphone (which is perfectly fine and actually recommended).
DT880's are world class. Keep them. I wouldn't even both sending them to have them fixed. I would have a professional recable them to a locking detachable cable. You get the length you want, plus an extension if you want, and your headphone now is essentially perfect (excellent sound, excellent durability and build, and the weakest link, the cable, brought up to excellent standards). I used Brian over at BTG Audio to do my cabling needs.
Here's what he did with my DT770. Locking detachable 4 foot midnight cable (braided and sheathed), terminates to 3.5mm, with a 3 foot extension cable with 3.5mm female and 3.5mm male terminations so that I can use it as a portable or on the desktop without excessive length on the cable, or I can add length to the cable if sitting further away from the source.
If you do however want a headphone to compliment the DT880, then I would imagine you should look at something less bright, warmer, and either closed back or simply with a different sound stage that is not similar in any way to the DT880 (or at least mostly not similar of course). A Denon D2000 for example would be a good compliment. Ultrasone PRO 2900 would be a good compliment. AudioTechnica A900X would be a good compliment. But again, unless you just want another $200~300 toy sitting on a shelf while you use something else, I would suggest you use your money to invest in your DT880 since it's pretty much one of the best headphones for the money and will last your lifetime if you take care of it.
