Stax don't need to try and push out the best cost-no-object gear in the world, they just need to fix their own issues and update their amps to be able to drive their own headphones. If you can CCS mod the 006t and 007t to be higher output, why don't Stax do it from the factory? If you can easily feedback mod the 727 and improve the sound, why don't they do it from the factory? Why do their headbands for the L300 split in half, the L700 mk1 y-forks break, the fit on the new Lambdas be significantly worse than the old? Yes they've taken a few steps with the Mk2 Lambdas to fix these issues but they need to be doing more. This isn't the 90s when they were the de-facto leader in the high-end space. There is much more competition now and frankly they need to get a move on or be left behind.
I probably shouldn't get into tuning issues as that is subjective, and lots of people are totally fine with how Stax voices their headphones. But I'm not. Over the last 5 years I bought the L700, L700 Mk2, and 007 Mk2 and they all have tuning issues to the point that I have to EQ them to make them listenable. When you can pick up a pair of $220 Sennheisers that's better tuned than your $1k+ headphones, that is once again a real problem.
This sounds angrier than intended, but I've been using Stax for over 15 years, I'm something of a fan and I just don't see things currently heading in the right direction.
