How's the highs on Rah for you? Do you notice any harshness sometimes? If yes, is it not noticable for you on OM, although these are more V-shaped?Rah's are (...) W shaped tunning
OM (...) tunning is way more V shaped though mid highs and highs are where the EStat driver deliver, there's details but no harshness, i still expect from time to time for the highs to bite me,though it hasn't happened.

no harshness for me on rah, i use the dark grey filters and red tops, on OM theres no harshness at all, as i wrote, sometimes i think they might get out of control in passages that normally are conflictive (all the Tellurian album by Soen, some old mp3's i ripped 14 years ago that i wont be able to get online, etc.) the rah has this nascar driver on the highs, i actually enjoy them quite a bit, they are never sibilant yet they get a nice real like bite; the OM has a 747 pilot, it just does it smooth, no moment of hesitation, just a velvety smooth scenary with the highs showing up, sometimes you feel the freight cause of the quality of the recording but nothing wrong happens with em, they know what they are doing.How's the highs on Rah for you?

On Instagram. Apparently Semper production was waiting on Sonion driver procurement.

Just hope that they are shipped before Brexit for non UK clients or we will have extra custom costs.

I would rather a delay for quality control on a limited edition product. Not like we can replace it later.

I hope we're not going to experience a delay like the one that happened with the EDP.

I expressed my hope for Semper shipping before brexit on his Facebook post. He only answered with a thumbs up emoji.

I just noticed the Sonion EST drivers on the top of the stack and the bottom of the stack have different lot numbers.
How good is Sonion in quality control between lots? Will people's units sound a step different?

Thanks, @Poganin. Now I'm having PTSD! Lol...I hope we're not going to experience a delay like the one that happened with the EDP.
