Speaker change

I’ve found Dynaudio speakers to be nicely detailed, refined sounding and musical.  I’ve not heard the PlatiMon speakers so take this FWIW, but reading some reviews while it looks like they would deliver on the soundstage/imaging front if it was me I’d be a little concerned they might be a little more neutral/white wine sounding than maybe you’re used to.  Also you’d be transitioning from an excellent silk dome tweeter to a very different AMT design, which might be great but is another variable.  Given where you’re coming from and what you’re looking for I’d go for Joseph Audio Pulsars (imaging/3D soundstage champs) that would seem to be more of a safe bet and known quantity, and the original non-graphene version is perfectly fine IMO and can be had used for around $4k, and that’s absolutely what I’d do.  But that’s me.  Just my $0.02 FWIW, and best of luck. 

Thanks for the solid advice, it's appreciated.

I’ve owned the Dynaudio HSs and really enjoyed them, and would agree with @soix that the Joseph Audio Pulsar graphene 2s are the best stand mount speakers I’ve ever heard in the sub $10k range. I moved to QLN prestige 5s’s. If you can find a demo pair of prestige 3’s (or new if budget allows) you’ll be blown away. 

Fully agree with @soix . The Dynaudio HS are a great speaker for the price. Would be hard pressed to find better at this price point. The Pulsars would be a great choice but a lot more expensive if not found on the used market. Had a pair of Harbeth M.30.2 it is in a comparable category with better mid-range for voices but lacking in some strenghts that the HS have. I now switched to the Dynaudio Contour Legacy floor standing. The Dynaudio sound is very well balanced with excellent tweeters, controlled bass and great soundstage IMHO.

It sounds like you just want change for change sake. That's ok. I have done it many times. I have regretted the switch as much as not. It is helpful to identify what you think you are missing. Dynaudio makes great speakers so you might just be bored.
