Tossing your opinion in this style here won't make any difference to the 007, only to your own (non-existent) credibility.
I am assuming you mean 71xxx serial, which can't be a 007A, so already confusion in your first sentence.
When set up right, the 007 Mk1 or Mk2 is special. Very sensitive to the chain, may never be quite as 'lively' as you might want. Each and every Stax has its very own unique style that might require some adjustment if it is not the style you image how music should be played. It's called personal preference. Which is fine, if you are able to express it in a way that a normal person would do. They all have their little nuances which you might realise - if you actually care to do that.
If you care to analyse the sound a little bit deeper (better), for instance, just take how a cymbal sounds, ignore everything else. You might realise that while the treble might be a bit lost in the 007's warm signature, it actually has one of the most convincing rendering out of all Stax headphones (I try to avoid saying 'realistic', because that's highly debatable and probably untrue). Some other Staxes I found have the opposite having either a very gentile or soft, or a very fast, less convincing cymbal rendition, but I don't notice that much while music listening because they have more things that try to grab you.
It is more to do with 'oh this is so bright', or 'oh, this is so dark, soft', whatever.
When I am varying amps or sources, the 007 can change a whole lot compared to other Stax phones - and unfortunately right now, I don't think I have the equipment where it sounds at its best.
But even that I can't dispute that the vocal rendering and focus (violin solos in particular) are more impressive than any other headphone I've heard so far, apart from the HE90.
So what you should have been said is that "I don't really feel like investing more to make something better, so I would rather just trash on it more as I used to and remain consistent"
