This costs a ton of money. But the build and options are why I know its going to work for me for … ever? I am currently pushing my L700 and 207’s with my Aune S7 pushed through the balanced input. Lots of options for those crazy Electrostats that exist. Really a special unit.
Electrostatic headphones require the best ‘energisers’ to charge them which is the secret of their performance.
The Pro iESL energises your electrostatics. And then some.
