Quick update. The Solaris SE were on burn-in for the last 110 hours so I decided to so a quick impression and compare to the Solaris OG. The only difference is this time I'm using the SXC8 cable instead of the Gold 16 since that is a more common pairing than the Gold 16. The advanced Sound Custom tips make it much easier to swap between the OG and SE due to the tip staying in the ear and the seal and insertion staying constant.
Ok boys and girls the bass slam is back but different. On the OG the deep bass sounds muddy not as defined as the SE giving a false impact compared to the bass on the SE. The SE deep bass and slam sound more realistic and cleaner. For example on the Blue Man Group Utne Wired Man track the Big Drum (5 foot diameter) sounds deep but unnatural on the OG. Almost like what you hear when you boost the bass cause you want to feel it. Then on the SE it sounds deep and natural like what I heard when I saw them in Las Vegas sitting in the 2nd row. Besides hearing the deep resonance of the drum you can now hear the skin vibrating.
Another comparison is on Lou Reed's Walk on the Wild Side. The upright bass sounds so natural now. Like what you would hear in a imitate jazz trio concert sitting in the front. The OG has a little bit more low end but at this stage I prefer the SE.
@ExpatinJapan said that he heard differences at 75 and 150 hours so I'm going to wait to do the full comparison at 150 hours of break-in.
In either case I currently prefer the SE due to a more natural bass with better details and a more open and wider soundstage.
I'll make the final call in a couple of days.
Remember everyone has different tastes and hears differently, so this is what I heard and I'm sticking to it.
