The SA-43 covers most of what you have and I would say it is somewhat close to the W4 with both switches off and not too far off the 530 with both switches on, but of course much higher quality sound. The presentation is much more laid back than the SM3.
My rotation is listening to what I am reviewing as I want as much ear time with it as possible with various sources. I currently have a backlog of products for review, so unless I am listening specifically for a question or A/Bing, I am usually just listening to the CIEM I am reviewing. Luckily they all are in the upper echelon of sound quality so it isn't so bad!
I have to say I never loved the sound signature of W4. As for me it has too lot of bass, lack of trebles and very veiled mid.
Shure SE530 has lack of details and brightness. And the major problem of SM3 (IEM that I like the most) is high mids. I just cant listen to any dynamic guitar music with this IEMs - it sounds like a mess.
The most balanced IEM I have listened is UM3X. They are quite detailed, have not too veiled mid, and not too bass like the W4. But I need more low bass than they have, more detailed mid and more trebles.
The same moment I really like the sound of LCD-2 or even HD-800 and look for something of a same kind but in IEM format.
So I'm not looking for something like my universal IEMs. I'm looking for something very different.
As for you rotation scheme. Do you use all of your IEMs for reviews or just several of them? What are your favorites?
And another question is which of your IEMs could be compared to SE-5 by overall quality of sound?
