supposedly the tube amp that Raal makes has even better bass (never heard it)
I can confirm this. The tube amp make a massive difference for them. You can surpass it with great speaker amps, but it will cost a lot more than the tube amp for raal does.
As for the CA1A, honestly, im not super partial to it. Its got astonishing detail for its price, but I find the image separation (especialy depth wise) extremely poor when speaking of the other cans in this thread. This improves greatly with filters (pretty sure its a phase issue), but also just ends up falling more in line with SUS and the like as opposed to easily surpassing them like SR1A does.
Hmm, i would think about that twice. Are you happy with the extremely good dynamics and bass of the 1266? because you will lose that, all of it.
Eh, Ill disagree here. you are 100,000% right that no estat (or frankly any headphone at all) will do the subwoofer like bass of 1266, but IME, estats not having bass is just a meme due to the very poor source chains that have historically been available. Stuff like X9k, OG Omega, and basically any lambda will get to 95-98% of sus bass on the right chain (that is to say, better than almost any sus chain, but still not quite reaching as deep as something liek AIC-10 -> sus which has a massive bass focus). The problem is, the more conventional estat amps dont get there just in terms of power (IMO, estats are currently where stuff like OG HE6 was when it released with just nothing realy able to power it).
Honestly, I have a pet theory that shang sr is just as capable (if not more so) than sus in bass. Its just that we dont have anything that properly runs it yet (not even T2).
Would have been more convincing if they don't also sell the LINA on their web site...
Yes. I wouldn't trust litteraly anything joe says about source gear. He is a dealer first and that clearly shows in videos. The lina amp
does wonderfully power 1266, but I've also heard it quite a bit better dollar for dollar.
What even causes the famous "low bass" on estats? Is the driver just physically unable to create enough excursion to reproduce low frequencies due to the internal design requirements?
See above in my comment. Its largely just due to the really poor quality amps that have been historically available (at quite exorbinant prices) for them IMO.
