I'm going to leave everyone with my final thoughts regarding the Shangri-La Sr.
This is going to be short and sweet. Some people may not want to hear it.
It IS the most technically proficient pair of headphones I have ever heard.
Detail retrieval, soundstage, and technicalities are beyond excellent.
Comfort, as per usual with flagship Hifimans, is excellent.
There is so much that Shangri-La does well, but for my personal preferences, it wasn't the end of the road.
Now that I own a brand new Susvara (this is my third Susvara) I have come to realize that I prefer a neutral tuning with a touch of warmth.
The Susvara fits this bill for me at a much more reasonable price point.
With Utopia 2022 as my more intimate complementary pairing, with the Susvara, I am fairly content.
The X9000 is also a very proficient headphone, and easily within a glance of the Shang, but once they make it back from RMA, I will be moving on, due to their poor quality control and driver reliability.
Some folks may ostracize me for not pairing Shang with a warmer chain, but I don't feel as though this makes a transducer worthwhile for me.
I ran a very reference chain and found the Shang a hair bright. It DOES take well to PEQ, but I prefer not to have to run anything.
Don't shoot the messenger! These are my personal thoughts and opinions.
Outside of trying out the Diana MR and Empy2, I am feeling pretty decent.
I have tried 90% of the gear out there now and I can safely say that I have found a good place to sit for a bit.
My closing thoughts are:
Shangri-La Sr. was absolutely worth purchasing to try in a quiet environment for a long length of time.
After a month, I can conclude, for my own preferences, this isn't my current end of the road.
It is a technically impressive headphone and one of the finest out there, but this didn't make it a compelling stopping point for me.
For a bit, I thought that I might end up buying Aperio and HE-1, too, but the Bravura made me realize that I don't want a system, for numerous reasons.
I'm sure that Aperio is right up there with Shang and that HE-1 is a marvel in its own right, but they're too expensive to warrant ownership.
In this day and age, with so many technically impressive designs released, I see no good reason to spend so much on a halo product.
This hobby is fun because of the folks I meet, and discuss with, and because of the different flavors we constantly try out.
Chasing the dragon has been fun, but the dragon itself doesn't exist. Some headphone, regardless of price, always does something a hair better than another.
I could buy the Aperio, HE-1, or another Shang, and still end up preferring the ownership of some less expensive headphones, to use when I am in different moods, or for their various complementary strengths.
