IMO the current range of Martin Logans shouldn't sound hard or edgy at high volumes. If they do, it's most likely the amp's protection circuits are cutting in and are causing soft clipping. This can produce a hard and flat sound.
If so, you need an amp with higher voltage output. Remember: with ESLs it's about voltage, not current, because ESLs are capacitors, not resistors. A Devialet can supply bags of current, which makes it brilliant at driving conventional (resistive) electrodynamic speakers, but not ideal for (capacitative) ESLs.
If you have an overly bright presentation at all volumes, that's more likely to be the result of room reflections or speaker placement. Try toeing the speakers out a bit and adjusting the feet so that the panel is nearly vertical. And get lots of soft furnishings. I think MLs prefer a fairly 'dead' acoustic.
But whatever the cause of the problem, you should know immediately when you've solved it, because the speakers will sound as smooth as silk and present a 'walk-through' 3D image.
