I have one from the first batch in my chain. Definite difference, but the impact is more similar to what I hear with R** reduction and reduced jitter in the chain, not the timing detail I get from mScaler. That being said, all of this comes together to a more "real" presentation, which changes the way I perceive music. As far as EtherRegen, impact for me has been obvious but not game changing, like it has been for some others (digital noise is a curious thing). I'm on holiday right now, but next on the "to test" list is to see if I can simplify my chain with the EtherRegen in place, and move a lot of the digital stuff to my MacMini digital server (literally) in my closet, and just have the end point NUC and EtherRegen sitting next to the Chord kit. I'm on a simplification purge after the recent Cambrian explosion of boxes and power supplies in my chain, so any simplification will be most welcome.
