I still haven't hit the purchase button for the AST yet... I really worry there is too much bass and too little treble - too early roll-off. It is USD90 with coupon and I just bought 3 cheap IEMs (one of them is GREAT!) and the Variations. Do I need one more pair...?

What was the cheap great one?

Will the AST be available in the UK on amazon? Its currently shipping from china with a month wait.

I think all measurements are similar. They all use the same IEC711 coupler which I also have one. I am not sure if it is just me or the characteristics of using pick noise to measure SPL, insertion depth, cable, source, etc. don't really affect the measurements. I can always get tepated results and I always use 15 times averaging so the measurements are even more reliable. Anyway, too save my time thinking I just bought a black AST... going to go back to normal price after a day and a half. Hope this can stop me buying too many IEMs...

That's nice for you but I have other plans which I intend to stick to.

Don't have spinfit tips.

I don't have the AST, but my experience with spinfits is that they tend to drop bass performance a bit compared to other options, which may be a desireable outcome given how the AST are tuned.

The bass is not bothering me now. Either my ears have adjusted to it or the bass itself changed. The bass is pretty tight now and can push some air for BA drivers. I notice that I can hear and feel the bass guitar better on the AST where my CKX is you notice the bass guitar is there, but rarely no impact.

I have replaced stock KZ startips with Spinfit CP145 on my KZ ZSX and I feel the bass improved but I believe that's due to a much better seal.

I have been using Spinfit CP360 (which is basically a shorter lenght CP145) but didn't A/B against the stock tips that came stock with the KZ AST.

I only have this spinfit tips that I forgot came with what IEM. Seems to reduce the bass a tiny bit and bring out the mid and high abit more forward.

Just FYI:
KZ-C style (covered pin like AST) pin has standard polarity just like other 0.78mm pins, but when you ordering cables with “qdc” finish, you may contact seller about polarity. If you use a qdc connector to KZ-C, negative polarity still produces sound but the the center of image may get blurred, which I happened to notice with my qdc cable.

If you find the original tuning too forward/sound pressure is too high, using qdc-pin may work as pressure-relief though. (not for AST at least)

I tried both CP360(my default go-to tip for multi-BAs) and other CP series, both CP360 /CP100+ worked great If you want to nerf the bass a bit and boost vocal, CP100+ (only available from Amazon Japan) is an option but it costs $14+14(intl shipping)

That looks pretty sweet, and $61 seems like a pretty good price.
Makes the ASX and AST seem overpriced in comparison.
I don't even see that product anywhere else. Strange. It's like a hidden KZ suprise!
