Enacoms for bright speakers?

Yes, but if they get rid of that HF "zing" will the C's still be "bouncy" enough?

Not if it don't mean a thing if it ain't got that zing, do wa do wa do wa do wa do wa do wa.

Thes still swing and zing as I found out, though not on Thiels.

Looks like piece of junk to the extreme. Maybe someone can explain how it works I'd be interested. The signal coming down my wire/cable is fine. I just get speakers that reproduce that signal accurately to begin with. That thing probably messes with the LCR values to electrically rolloff some of your highs--who knows. I'll have to admit I'll laugh even harder for the audiophile who's already got $1,000 speaker cables on his/her system ("to correct for the distortion imposed by the cable") and then buys that thing the damage the signal more. (of course their tube amp has probably already done the real damage at 10%THD--and rolled off the highs. So if you own a tube amp you'll never need that thing-its already distorted the signal for you). Get good speakers. $85 dollars in room treatment or deadening your speaker cabinets will get you more mileage.

...and what about RFI,EMI? EZ, although at least theoretically I shared your scepticism, was pleasantly surprised though. Here is a siteabout them :
