Had 'em. I ran them with a McIntosh vintage 2505 and then later an expensive Rotel 200wpc new silver thing. I traded the Rotel in for a 2205 refurbished Mac and had the same results. Funny since the Mac with transformers are so laid back. They sounded harshhhh. I had hardwood floors and this may have contributed. Later, I had a pair of Thiel 1.5 speaks. A different experience. Thiel is known for thier drivers. The later (1.5 or 1.6) is better in my opinion. Save a check and pay the x-tra 500-600 for the 1.6, or if you have the room and strenght to move them, buy 3.6 if available. You will find them. They're great with single vocal Tuck and Patti type stuff, not so much with busy music.
Hope this helps. Just my sense.
