Actually, I'm very pleased with the sound from the phones and setups I have now. My recent experience with the HE-500's and the 007's and 507's has convinced me that the sound doesn't get much better than what I've got - only very minor differences - certainly not justifying their high cost, and special amp requirements, which add hundreds / thousands more to the cost. The magic is in the "synergy" of the setups with the phones, and the tweaks.
Oh... I might experiment once more with the PS1000's (their signature would be consistent with my preferences)... but... likely not, since they're not so popular, and the resale market isn't as strong, and once again... there is the very real fact of "diminishing returns."
So... unless... I'm willing to spend many thousands to try the high end Stax Stuff with the best amps (which I'm not)... I'm pretty sure I've reached the "pinnacle," though I might try a better SS amp, like the B22, or V200, just for fun with the phones I have.
