nope, i still need to get them recabled. maybe that will make some improvement. as of now the HD 800 unbalanced sound better than the T1 balanced, though I still like my T1, i just haven't listened to them as much as when I had the WA2. honestly it sounds like the GSX MK2 is better than the WA2 by a good margin, just need a little less treble a little more bass for the T1's to get to that sweet spot, don't know how much the balanced would help.
Yeah, that might explain some of your results as you're only using 1/2 of the GS-X Mk2's circuitry and power. Not sure what differences that will make against the WA2 though?
