I forgot to mention in my prior 2 posts about the high frequencies of my Thiel CS 2 2 speakers not sounding as smooth as they used to be. About a year ago I cleaned the entire dusty grille without taking the grille covers off, I used a powerful central vacuum with the soft bristles attachment on a long hose. I don't remember if the speakers were playing or not. After this cleaning, I did notice the highs sounded a little different to me, slightly distorted or scratchy? I have read that these tweeters are highly sensitive and this may be my 1st place to look. I believe mid and woofer still sound good. I will do a listening test today. I will have to call Rob about tweeter rebuild or replacement units he may have. I checked Madisound and their replacement tweeter for my model is out of stock. I didn't receive any responses if anyone had tried the Emotiva Basx 2 or 3 amp with these speakers and were happy with it. Currently using Denon Avr X4200 in a 7 ch setup. For CD and Phono using in 2 ch to achieve highest wattage.
Thanks to all and look forward to your feedback. Richard
