The common wisdom calls for these speakers to be used with tube amps to minimise the "brightness" and give them more "life" than with ss. They have always been an exceptional speaker and I still enjoy them at a friends house. They are certainly the equal of anything anywhere near there price. There is also a slight improvement if you bypass the mid & high speaker controls. Also sound a little less harsh if you use silver wire to the tweeters. Enjoy them.

Let me know if you have or have listened to these speakers. I have owned a pair for the past 2-3 months and they are really nice. I own a pair of Pinnacle Aerogels that don't have quite the detail or quickness in the midrange and tweeter. I have not heard speakers this nice under $2-2,500. Really unbelievable!
