Speakers for aging audiophiles - What's with today bass emphasis ?


I'd love to pick your brains on a issue and possibly a suggestion
My system has 2 sources, a Logitech transporter and Thorens 126 MKIII / SME / Supex.  Ampli recently changed to a Musical Fidelity M6si. My listening is 80% streaming and 20% vinyl. It's mostly classic and prog rock but also acoustic jazz and classic chamber music.
I have an issue with my current speakers setup: Dynaudio BM6 passive.
I have been using those for some months now and find that while they are satisfying in terms of scene, detail, resolution they are exceedingly strong in the bass (say 50 to 200 Hz) and not adequately balanced in the middle / treble, say from 1k Hz up. It seems as though the bass player stand in front with a big amplifier and everyone else is back in the stage.
I have changed the amplifier to the Musical Fidelity but while I am happy with that I did not see much change in respect to the issue I am describing.

I relate this issue to 2 causes:

1. Today's recordings emphasizes the bass unrealistically. Let me just give you an example. I recently bought Steve Wilson remix of Marillion "Misplaced Childhood". Great work. The mix is shining but compared to the old vinyl I have got you get this feeling of too much bass. Bass quality is great, well defined, solid, no complain but just too much of a good thing.

2. I am ageing, over 60 now. It is well know that as you age your sensitivity to the high frequencies falls down

Given those factors I'd like to change speakers to get something that:
- Is very open on the highs
- It's very analytical
- Does not over emphasize basses
- Bookshelf
- Ballpark cost 2 - 2.5 K

Can anyone make suggestions ? I was inclined to the Harbeths M30 but read several blogs where they say they do emphasize the bass. Maybe Dynaudio Special or Focus  ? How about Totem Sky ?

I don't mind spending a few more bucks to get what I want / need.

Thanks a lot everyone.

Note: When the NS10 started showing up in every recording studio I started dreaming that one day I could gather all of them up and burn them all in a giant bonfire. Sad but true.
It’s just not a great speaker. In that size try the

1. Canalis Anima with a nice amp of your choosing.   2. Amphion One 18, with amp.   3. Powered ATC SCM 20 Pro mk2
Don’t abandon the Harbeths. In my experience they are incredible. I have the SHL5+ and they are the most open, have perfect midrange and the bass isn’t emphasized or bloated.

I believe any of their bookshelf models would serve you well.

Lots of good advice here.  I own the LS50s and was having some similar, but somewhat opposite, sound issues.  I ended up drastically changing the room arrangement. The speakers now sit 65cm from single pane glass wall and are 2.8m apart with a VHT sub in between.  I did a bit of research on the reflective index of different materials as I was looking for a "fuller" sound.  I also have the old, front ported B&W CDM1se and they are basier than the LS50s.  I don't use them much anymore.  I keep the sub volume at min.

With all that said, if I had to do it over again, I would get stick with Dynaudio and get the special 40s.   They are impressive, and I love the LS 50s.
