This is debatable but here is my gut instinct on Thunderpants.
better than stock? Sure it is, but $500? After listening to Sherwin's I would not think so to be honest. It maybe a western labor of love price but locally it could be duplicated for far less given our talent at disposal.
Not just duplicated Marcus. You saw the shoddy craftsmanship in how the cut belt was attached to the headband, how the pads were sloppily glued to the cups, and the frail-looking wires that went out of each cup. We have modders here who could do a far better job.
But likewise, I don't want people to think that I am just blindly bashing the TPs. There are people who will appreciate its sound. And truth be told, we have a legion of people who love the M50 here. To put things into perspective, I think the TPs sound better than the M50. But to me, they don't sound (or look) $400 better than the M50, and let's remember that they do cost $400 more than the M50s do.
Now, we can't really tell people how much to price a certain anything.
To be honest, the LCD2 at $1000 is also pretty overpriced. But to me it was worth that price, so I didn't mind paying it. The sound was what I wanted it to be. The wood work and the leather work were excellent. Detachable cables? Check. All in all it was worth that much to me.
The TPs just weren't worth their asking price for me. But I can't make that decision for everyone. You'll have to really figure out for yourself if it is really worth it.
