I’m bad with throwing impressions and benchmarking, but one least noticeable aspect is the soundstage. GM features a toggle to adjust vocal proximity, which is unique. The multiverse mentor feels more spacious, with distinct layers of details. Overall, both are on the summit fi level, and that's the main takeaway from my experience with both.
I heard both at the same show. I can't recommend the Mentor Multiverse in 2023. As someone who has owned the Mentor V1, V2 and V3 (yes this is a 10-year-old model/series), I thought the Mentor Multiverse inherited the Mentor's signature sound (kudos to UM) along with its biggest shortcoming: a distinctive boxy-ness in the uppermids. At its asking price in 2023, I don't think it is acceptable.
I tried the CP240 with the Scarlets. I didn't really like the pairing too much. Felt a little bloaty to me. Felt it killed the soundstage and any sense of air. More bass quantity but not as defined. I think its hard to be sensitive to the treble on the Scarlets because if you have the volume up that loud to the point treble is causing you problems then you are definitely going to be having problems with the bass. I learnt with the Scarlets that sensitivity swings both ways. Bass fatigue is real. Treble sensitivity to me is like 'uhh make it stop now', where as bass fatigue is like 'urgh, this is becoming a mission to listen to, i think i'd rather stop' after like 30 minutes.
Yes, they aren't the most comfortable of the tips i tried, but they do seem to sound the best. I will give it some more time and experimentation.
Have yet to receive my scarlets, but I'm using the tri clarion tips with my Maestro Mini currently. They seem to work fine enough for me.
i hope my GF will not be jealous about "scarlet" 
I reached out to cancel my order a couple of days ago for my Scarlet and they replied immediately saying that it was in the final stages of production and that they wouldn't be able to. They said that I should expect them to arrive in 1-2 weeks. I pre-ordered at the beginning of October for reference.
Thanks for the reply. I don't think I want to keep waiting in particular when they go silent. I understand if they are trying to not compromise quality but not communicating is not the right approach.
At the beginning of december I asked them about mine, they told me currently in production and expected to be end of december or "latest" beginning of january. I've ordered it on 5th october.
In November, however it is very easy for them to have someone just contact all orders and provide a status. If you do it the old way you can outsource at cents on the $ , which is the easiest nowadays. I know they are a small shop hence the suggestion. Will not cancel as I still want to experience their product and support a new business.
