I understand. Took me a while to appreciate the 009S and the 007. I, in fact, sold off and then bought back the 009S.
I realized that once you give yourself some time with either, and are mentally able to overcome comparisons, with certain genres, estats can be shockingly immersive. And its not just one or two specific genres. A diverse range of artists, from Clapton to Porcupine Tree, works wonderfully well with estats. You are just sucked into the delicious delicateness. DAC-Amp synergies are important, as is well known, for stats.
I was also thinking how I just love the spread of sonic signatures encompassed by the 007 and the 009/009S. Stax did something rather brilliant here, by creating HPs that sound so different.
The CRBN being a halfway house between the 009/009S and the 007, whilst having a bass far less impactful than the 007 and detail and speed less than the 009/009S, does sound uninteresting to me, to be blunt.
The Shang SR sounded like the perfect headphone, from early impressions, estat or otherwise. So I imagined it would have a higher quality and quantity of bass than the 009/009S. But nothing is perfect quite clearly, lol. But if the SR, as you put it, has better imaging, details, and other technical and perhaps tonal attributes than the 009/009S, then, yeah, that still sounds interesting, I suppose.
But given value and build-related concerns most have at some level, including myself, the attribute that the SR bass is probably at the same level as a SR009/S, does discourage a bit.
This is my subjective take only. But I guess I would have jumped on the SR if it was more of an unequivocal home-run. Not that this perspective should apply to anyone else.
TLDR: Your impressions are valuable
