KTXPRO1

Yes! I usually only play with headphones in the $200 and under range. I actually don't remember when I last paid more than $100 for a pair recently. I pretty much like anything from koss, I haven't tried the porta pros or kph-40 yet. The kph-30 and ktx-pros are good but the ksc-75 are still my favorite. ktx-pros are a little more warm and basey very similar to the kph-30. I never had a pair of mdr-7506 but I still have a pair of V6, but I don't know if you can still buy them. They're great for pop. I also tried some used Grado sr80s and I didn't like them as much as I'd hoped. They sounded really bland, like little to no base and midrange. Still like grado as a company and think they're worth trying again especially if I find a demo setup. I want to save up for some berrdynamic dt-770 or dt-990. I remember trying them in microcenter once and loving the sound.

I had the same Audio Technia headphones - 2 pair in fact. I, too, play through a Katana Mk II and they sounded really good. On both pairs, the plug got loose and eventually they quit working. The wiring is so tiny that there is no easy way to repair them. They weren't abused. In fact, the one set was always plugged into my receiver. I went with Samson SR850 after being recommended by 3 friends of mine. They sound perfectly fine to me and almost as good as the ATs. The price was right too. Ymmv though. I still miss my old Koss Pro 60s. No boomy bass or harsh mids ....
