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.

When I used a sbooster in a device, noticed a difference. Use these guys for a 60 day return.

Also I can’t imagine that this company would advertise it, if there wasn’t a difference. 

@gkelly  Thanks. I definitely noticed it with my phono pre-amp. I live in the UAE and order directly from the company (although they are Dutch, the head office is in Romania). I will check with them on return policy.

@tablejockey Thanks for your input. I used ARC to get the set-up done and ended up with almost exactly the 4 feet from the back wall for best sound. Cables are decently priced Benchmark speaker cables and interconnects, nothing extravagant.   

When inquiring, ask about aftermarket AC power cables. Thinking with such a nice toroidal transformer that it would work well with a fat cable. Sorry for spending your money 💵. 

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.
