I don't normally bother posting on these topics, since it's all so silly and everyone in audio forums seems to be going about this
all wrong.
Don't all "real audiophiles" have a dedicated internet connection solely for their music streaming service? And a separate service for browsing the internet, etc. (Remember that if you have subscriptions to multiple streaming services, you must have a separate internet service provider and path for each one, well-isolated from each other.)
Maybe that's the real problem, these audiophile wannabes are trying to use
one internet connection for everything. How lame! If they had a dedicated connection for audio only, they wouldn't need the 'band-aid' of these cheesy 'regen' or 'isolation' devices. hahahahaha!
I'd bet those audiophiles who sensibly get their own transformer from the power company know better.
