Impressions wise, not much more to say than what other's have mentioned about the Solar and Galaxy. Both are amazing IEM's but different flavours. Solar is skillfully coloured for an indulgent experience where as the Galaxy is certainly more studio monitor type presentation. Both are up there with the best. I'm not sure which I prefered - I loved them both! I did however get to try Sammy's new IEM . For me this was almost a bridge between Solar and Galaxy sound sig. wise. I'm not going to say anymore than that as I'm sure Sammy will reveal more when he's ready! But it is very good.
