I wish I could hear a T50v1 to actually know what class that is, but by all accounts, it's amazing. My definition of good sound seems to be kind of different from the majority, even of the ortho crew, so don't let my craziness get to you. I actually think mids that are too forward are fatiguing; moreso if they're aggressive. Not sure about a bass hump headphone, I've always immediately damped my orthos upon receiving them and the only bassy headphone I owned that I didn't mod was the MP Sextett, which I immediately sold off. Can't wait for your impressions on the HE5 and a comparison with the LCD2 later on.
