Hassle? Let us please not exaggerate, or mix the empirical with fact.
Some of the models i own are about 40years old now? Bought them myself, have not had the slightest issue with any of them, ever. There's this piece of paper inside the box, advising one to treat them as what they are, a precision instrument. If heeded, they can outlast you.
As to amps, well.. did you purchase a used one? One from the grey market? Because those bought from a local representative need only be mailed back to them and they take care of the servicing. If that isn't the case, the blame lies on the representative, not Stax. You should have contacted them and let them know if so.
Same goes with used headphones, which i see is a trend, the electrostat's extremely fragile nature notwithstanding; this is an expensive hobby, we buy new, or we accept the inherent risks thereof.
* likewise with "modding" your new headphone, because certain "someones" told you to; if doing post-purchase alterations, ie voiding your warranty is difficult for you? Why, i'd say we're on a good track, wouldn't you?
I'd also have a lot to say about the previous poster's message (stuck in the past), but in one sentence i'd state that on the contrary, i happen to wish we went back to that past. Some of the electrets they launched have yet to even be matched, let alone surpassed. And did that at prices even folks like me could afford.
If you want progress, you picked the wrong company. All they have done (success rate varying) is reiterate on said same basic principles and implementations. Expecting otherwise, today or in the future, is your (read: figuratively) fault entirely.
Should one find that a 5.5K (at minimum) headphone, that "gets real close" at that, ie not even
as good, is a welcome alternative...? Why by all means go for it.
Their amp section is in need of improvement, yes, but i'm not sure if that is grasped the way i meant it to (my criteria are not the ones i typically find expressed here), or if some understand the limitations (supply, logistics, etc.) they have as both a proper company and a small one at that. Put differently, an utterly derogative dismissal is a touch excessive.
And please accept my apologies in advance for all the above, but misgivings i may happen to have set aside, i wouldn't wish to be seen as sharing such a negative mindset; saying this as i was the first to complain unfortunately
