@mikey8811  : update 

I tried my EtherRegen with and without opticalModule. No difference that I can discern. Not even sighted 

@thyname thanks for the feedback. I read other reviews and there are some folk who find the ER causing a loss of body and warmth and sounding too smooth and clean. If that is the case, I don't think it will work for my tastes. That is the impression I have had with other Uptone products in my system. I would put them in the category of "you hear more but may not like what you hear"
@david_ten thanks for the tip on the Japanese switch. That sounds like it will work for me. However, the price is staggering.

My experience has been different @mikey8811  but of course, that’s just a subjective data point. As with everything, nothing replaces your own experience, in your home, with your own equipment.
