What dynamic spkr. did you go to from electrostat?

I went to a PBN Montana epx speaker from the ML Prodigy. Much cleaner impact on the low end side. Mids are more realistic, However, you will not find a dynamic speaker with the same upper register holographic magic that the panel speaker gives. It is close but not the same.
Which is more realistic is up for debate and personal preference. I would say system synergy and room dynamics will play a good role in your search. Go listen and determine for yourself. Thats the fun part.

There is a coherencey about a well designed dynamic speaker that you will notice over the ML. Once you get to that level of speaker, each has its trade-offs from perfection but all are so darn close it comes down to personal taste. That said, I do miss the magic that the panel gave.

When I designed and built my subwoofer systems (one 2-driver system for each of three front speakers) I was thinking about LF extension beyond the 40 Hz that my MG1.6 can do. However, as things have evolved, they let me go from cone drivers to panel according to the type of music I am playing, just by varying the X/O frequency. I must note right away that this is only possible because my subwoofer systems, which are flat to 20 Hz with a bit of equalization, can also go up to about 400 Hz without distortion. (This would not be true of most commercially produced subwoofers). Also, you need an electronic crossover where the frequency is easily adjusted with a knob. In practice I use X/O frequencies from 40 Hz to about 300 Hz according to the type of music. When I vary the frequency I am really transitioning from cones to panels. There is no doubt that some music eg: loud organ music, benefits from the power capabilities of six big (12 and 15 inch) cones driven by six 600 watt amps! On the other hand, quiet classical chamber music does fine with just the Maggies. Best of both worlds!

I have been an electrostatic guy since the very early seventies- Quad ESLs (which I still have, along with a matching set of Quad mono tube amps); then Crosby-modified 63's (which I also still have, used with vintage ARC stuff).
I also wanted more impact, bass and dynamics. Went with Avantgarde Duos. The horns can give you what the Quads cannot, but still have an incredible ability to articulate, move 'fast' and sound boxless. Voices will not be as translucent as the Quad 57, but then, no other speaker that I have heard, including the later Quads, do as well either. (The trade-offs though are enormous, in terms of SPLs and bass, or lack thereof- the Quad 57, set up right, in the right room, is simply uncanny, but it is very limited). The horns give me a compromise I can live with.

I went from Innersound Eros to a VMPS, better all around with most of the magic from stats with much better impact.

Went from Maggie 3.5 to Watt Puppy 7.0. Loved the bass, miss how transparent the Maggies were... WAF was not good on the Maggies either. WP's sound good with tubes, ARC voices their stuff with Wilsons I think. I think stats are like that one old special lover, the new one may be better in lots of ways, but there was that special thing...
