Smaller plug-in AC Purifiers -- Shunyata, iFi, Puron...something else? What do you like?

Thanks for the review.

I cannot tell how to buy Telos Mini Q or how much it costs.

@sns 
I already love my Audience Adept r2r plug. I just notice that the Shunyata makes it even quieter. I'm trying to make a small additive improvement, not spend that much more.

@erik_squires 
I guess I could add a second power strip...

@rsf507 Not there anymore.

$400 is a lot for a plug-in, in my opinion, especially when I'm seeing people say (about these and others) that multiple plugs are better. That adds up quickly. To each his own, of course.
