Lawton modded D7000 and TH900 don't sound the same at all. I had the lawton modded D7000 and I wasn't impressed by the mod. The only reason I got lawton pads was to replace the original ones, cause they were worn out. Otherwise, I would have never bought the lawton pads as they are extremely overpriced and change the sound signature of the D7000. The reason why I owned and loved the D7000 in the first place for so many years was because of its amazing sound quality and sound signature. The lawton pads took out that joy and made the headphones somewhat boring and the sound like it was coming from inside a cave. It had a weird effect. I preferred the original pads over the lawton mods any day.
I just couldn't find the original pads anywhere to purchase so I was forced to buy the lawton pads. I ended up selling the D7000 with the lawton pads and after selling them I found out where to buy the original pads. But it was already too late by that time, cause they were gone to another owner.
But I'm glad I sold them, because I now own the TH900 and they are the greatest headphone I have ever owned. I've tried a few 1k+ headphones and a lot of them were a huge disappointment. The TH900 are a pair of headphones I do not regret spending my money on. They are an absolute masterpiece from its design to its sound quality. I'm actually surprised these headphones are not mentioned as one of the best headphones ever made open or closed.
Also, the TH900 are an improvement over the D7000 in every area modded or not modded.
TH900 bass is probably the best I have ever heard on any headphone.
Sounds like you are confusing Lawton pad replacement of your stock pads with the Lawton DAMPING mods. Totally different conversation. I agree the pads are overpriced and not worth the price which is why I have the Alpha pads on my D7000.
