Sure!
Having at home both se200 and se180 I made a blind listening with a generous help of my beautiful wife. We tested se200 AKM side (4499) vs se180 sem 2 module (2 akm 4497 dacs), volume matched, with Fir Audio M5 iems as transducer and 2,5 balanced Nobunaga cable. The test track was Thomas Bergersen's Apollo from Humanity IV album.
Nothing strictly scientific, the aim was to better understand how I hear differences (if any) and summarize my impressions, to do so I took notes during listening and wrote done my guesses on device playing.
10 tries took around 40 minutes. I obviously didn't see what device was playing at moment and each time earphones were re-plugged.
So, to my surprise, I guessed right 10 times of 10, two times wifey turned on the same player in a row.
So here are my impressions:
Se180 Sem 2 (compared to se200's akm output) gave me more spacious virtual scene, with better instruments separation, and overall more refined soundscape. It was also very apparent that se180 had more dynamics, which led to more emotional performance.
It sounded more natural and effortless, with deeper and more detailed bass. It was easier to focus on particular instruments on the busy orchestrated parts of the test track.
The background noise was literally absent, it was dead silent (and se200 is no slouch in that department already, being one of the quietest players I ever heard).
I'd say that se180 with sem2 has less coloration with better technicalities.
That's matched my first impression in a shop when I heard it for the first time. For me se180 soundwise is hands down better (than se200 and a whole lot of other DAPs).
So the other day I made a blind listening se180 with SEM1 VS Chord Hugo 2, but that's a story for the next post
As always, little bragging: won't it be great to have HIGH / LOW Gain button in the Notification bar? Just imagine...
