I share the same sentiments with the SD5. It has a strong 8k peak which I am sensitive to.
Have you tried the qdc gemini or 8sl/8cl?
no i haven’t, because i witnessed/overheard a rather unfortunate incident wrt a qdc owner at a local store last year (the owner only had it for 2 days before one of the shell cracked) so i, perhaps unfairly, wrote them off as “another” outfit with questionable QC, time to give it a go i suppose.
I see that you are getting a futuresonic ciem soon, i hope it is much better than the g10, which to me, is a great woofer in search of a tweeter lolsigh, it is so dark that it made the se846 sound bright lol.
