The Op-amps in the A30 are indeed socketed

Nice Review here, for the A30 I think I might try getting these other OPAmps to test it like you suggested.
Which ones did you swap it to?
I've only tried one other which are not cheap, the Burson V5i Duals, but they are well worth it, was not expecting such a jump in sound quality.
As another update, I have just taken the TI OPA2227 out after some A/B testing (I have 2x A30's one is stock) the 2227 results in a slightly "harsher" sound, I think this is due to the low slew rate which doesn't curb all the artifacts.
Some might argue that it is more "natural" but sometimes "natural" isn't good if its harsh. I listened to about 30 hours of music on the 2227's and most songs were fine, but then I came to a couple songs with some some Cymbals and they really came through with a harsh tone that made my ears start to hurt due to overwhelming sharpness.
I tested the stock A30 and while its still sharp, its not harsh.
After going over the track about 5 times in a/b I concluded that the 2227 is infact not a good option to roll to unless you like your music more "raw".
Edit1:
I have now rolled it to a LM4562NA and will report back on my findings.
Edit2:
In my last couple minutes of testing, upon testing the rolled A30 with the LM4562NA the harshness was gone (from the 2227). Additionally it has cleaner than the stock A30 (OPA 2134), I would say what sounds like slightly more depth but it is tapered from harshness.
This is more in line with NwAvGuys findings where the LM4562 is better performing vs the 2134.
I will report back more information though because I have only tested 2 specific songs.
THe first is "This Joint" by Slightly Stoopid and the second is "3:16AM" by Jhene Aiko
This depends on what you listen to and what your gear is.
The topping stack is more reference. My Schiit stuff doesn't sound reference at all and I am looking to sell my modi 2 multibit actually.
It doesn't really sound very good and plenty of different music has artifacts with it.
Its because it doesn't have proper filters like DS dacs and most ADC these days are also DS.
I Daily my A30 and swap the dac around sometimes.
BUT I use the D30 most of the time.
I am using the M1060s as my daily headphones. I also listen to a little bit of everything but mostly all flavors of rock/metal. I want to use the dragonfly as my mobile dac since I joined the hd6xx drop.
Then you should be fine with the A30, it can drive basically everything. I see those are planar headphones, they have higher power requirements but the Topping has high power mode aswell as a larger jack for bigger headphones.
But definitely for the DAC stay away from the Modi Multibit unless you like things like tube amps that alter the sound. Because it really was a disappointment with any modern music especially.
