Yeah, I'm selling it off. It's been good to me, but I really have my eyes on the Alpha Dogs coming out around the end of this month. Lately I've been playing games where I don't need a mic on my Mad Dogs, and I haven't played a ton of games where I needed chat functionality. The Mad Dogs are more comfortable than the Q701 are. I like the heavier weight they have and their clamping force is just perfect for me.
Lately I've been looking into upgrading my MD to AD, maybe getting the X1 as my next open full size headphone, and then after those maybe save up for a new amp to replace my Aune T1. But for now the T1 is a heck of a little DAC/amp combo. A bit sad I only get the tube sound when going USB, but I like what the package offers. Can't complain at all considering I got it for about $115. And as far as selling goes I may be selling off a couple other things here and there, though they're not really anything special; Monoprice headphones with Beyer DT250 pads and things like that. Just trying to consolidate things into a smaller collection with a focus on end game. I figure the "fun" X1 would go nicely with the reference ADs, plus the X1 would be perfect to use with my BoomPro mic that I currently have on the M-80 when I play using them.
I haven't seen anything about the mod. I'll look it up, but I have a potential buyer lined up already and I'm still planning on going through with the sale. That money is needed elsewhere right now.
