Duntech Black Knights to Martin Logan Summit X

I have not had that many speakers, just had some electrostats (Acoustats 11 and ML ESL) before and liked their holographic sound stage abut never had a chance to compare them side by side with the Duntechs. Since I like rock, the Quads are probably not best suited, hence the quest for something more modern to replace these black monoliths.

First of all, the genre of music I mostly listen to, as my moniker suggests, is Jazz but occasionally I listen to some classic rock. I want to ensure the next speakers master well the imaging, clarity , dynamics yet still are neutral enough. Not just because I have had electrostats but I did listen to a Summit X in a show room and liked the sound, I prefer the Vandersteen 7 but that is now out of my budget. Looking to spend up to 8k for a worthy successor of the Black Knights in the used market.

Thanks for your comments Beachbound. I am a bit familiar with the designs of Revel so can relate to your upgrade.

Diana Krall in my room? Yes please!
