Wilson WP 7s and supertweeter

Try adjusting the tilt of the head. Nothing wrong in trying but I doubt it will blend perfectly.

A Berylium tweeter or a Ribbon or Scan Speak will have more air but for me all but a Ribbon sounds less natural. Also, your cables can be a big problem. What speaker cables & interconnects are you using? Lastly, this seems like a first so please try & let us know. Maybe a rear tweeter for ambiance might improve things. Considering all the amplification you have tried, I still think that some times a system synergy. Any networked cables will reduce highs.

Stealth should be pretty good. Indra might be a little warmer in sound though. I am a Tara fan. A silver cable will definitely tilt up the highs. Not to my liking.

Thanks. Was always in flux but now too happy to change much. I wonder if the supertweeter can function as an ambiance tweeter as in the X-2s. Might be very cool. I am very against hissy highs tough. A ton of equipment is voiced as such these days.
