Nothing that I can think of at the moment. The UE18 Pro would be a good one to obtain
if you had to get another C/IEM, but probably has 75% or so amount of bass the SE846 has. Instead of purchasing another C/IEM, upgrading to the Hugo would be a much better way to keep using the SE846, keep using the SE cable, and hear a
n almost tangible difference regarding elevated sound quality, even higher sound quality than the AK240, in my opinion. The Hugo is just butter baby!
That was one of a few impressions I've posted regarding the Roxanne. Others can chime in about the Roxanne for sure, but if you want to know something specific, ask away, as I have demoed both the AK version and regular versions with balanced and SE cables. Do I think they are worth the price if you already have the SE846? Not by a longshot.
The K10 would be a better complementary IEM to obtain if you were itching for a C/IEM, even though it does not have that strong of bass in my opinion, as it's more of a musical, slightly off-neutral IEM.
