LPS for Martin Logan ESL 9: Will it make a difference to the sound?

I use the predecessor to the ESL9-Theos.

The major difference being the woofer cabinet, otherwise identical panel dimensions.

The wall warts are just providing positive/negative voltage to the opposing stators. Doubtful.

Placement/location is paramount- away from the front wall 4-6 feet for the magic to happen. Moreso than cable/jumper neurosis.

I'm sure your ESL9's sound great.

Haven't heard them but with the reworked woofer arrangement, low end performance must be improved compared to Theos. I use 2 subs to make up for their bass shortcomings.

Sbooster can improve in certain situations, as you've experienced. In this case, expectation bias, if anything? This hobby/obsession is supported by it, so perhaps it will help😂🤣!!

Years of living with the Theos, I still hear moments of greatness from them.

If I do stick with panels during the "big upgrade" it will be BIG panels like Soundlab.
