Anole VX is the SA6 with much more resolution. VX is better, the tonality is very similar though. Higher resolution than anything else I have heard, other than the Shure KSE1500, and even that it's on a similar level to. Higher resolution than the the MEST, it's really on a different level to other TOTL IEMs. The negative is it's maybe not quite as natural sounding as some other IEMs. I'd still take the Monarch Mk2 as a more natural sounding all rounder. I don't find the Anole VX too bright, but I'm not sensitive to very high frequencies.

It's much more expensive than the SA6 too though. But just to throw it out there as something that is tonally very close to the SA6, but absolute TOTL resolution.

My own graph possibly even closer

The SA6 Ultra was very well received, if the new SA6 is similar to that it could well be a winner.
