I think swearing and farting as you get up because you need to change the volume as soon as you sit down, is much more detrimental to a listening session than a remote.
I’m really enjoying the Burmester 088. A used one would be in your price range. It has a fairly logical line of sight remote, but it can also be run from the face plate controls. Mine is paired with a Burmester 911 mk3. It sounds like a synergistic match up here.
I know this is an old thread, but do you still love your Esoteric C1X solo? Is there any material difference between the C1X and the C1X solo (other than being in a singular box).
I'm currently vacillating heavily between a Nagra HD preamp and C1X solo -- the Esoteric being a fraction of the price.
