OK updated impressions. I burned the SE in for 180 hours on high gain. Again I listened to a mix of 16/44.1, 24/96 and 24/192 FLAC files and some DSD. I'm using Advanced Sound Custom Tips which makes switching better the OG and SE easier along with ensuring that the depth and seal is consistent. For my final impressions I switched to the ALO SXC 8 Balanced Cable which is more common than the ALO Gold 16 I previously used. Also after my previous impression post, I did some experimentation with the OG and SE on the Sony NW-WM1Z and found I preferred Low Gain Direct Mode over High Gain Direct Mode.
I added a new track for the testing, so here is the updated list in an easier to read format:
Before doing the comparison I went thru every track to determine the best volume while using the OG. It was interesting that the volume levels ranged from a low of 50 to a maximum of 75. But the most common level was 60.
For the comparison, I would set the predetermined volume level for a track and then listen to it start to finish with the OG and take notes while listening. Then I would switch to the SE and again listen start to finish and write down what was different to me.
So what's the verdict? It's a keeper.
Why? Overall I found that the SE sounds more open and has a wider and deeper soundstage. More of a 3-D sound. I also find that the vocals on the SE are more forward than the OG which at times seems to be recessed. A lot of the acoustic instruments; drums, strings, horns and piano sounded more natural. To me, the SE sounds cleaner more refined. Be warned, there was a big difference in the bass between first listen and 180 hours. So don't rush your opinion.
During the comparison session it felt to me that the bass on the OG (which has over 300 hours on it) was more muddy versus the SE which was just as deep but cleaner more defined. So the SE doesn't have more bass, it just has better cleaner bass.
Finally, the more I listened to the Solaris SE I keep thinking of the Andromeda Gold SE. The sound is very similar, but the Solaris can go much deeper. I'm going to have to do a head to head with a lot of different genres and track resolutions to see which is best for what. I consider myself lucky that I can afford both SE models.
Thank you
@KB for another outstanding IEM.
