Have used Tektons with a number of t amps including Virtue, Audio research and some $60-variety. They work very well with t-amps. They work well period. Also have used my Tektons with streaming from Duet using lossless compression, radio, Pandora, and Rhapsody. Also have used Tektons with tubes (Rogue and SET) and solid state (Moon). No problem. Other speakers used recently include Ariel, Magnepan, Def Tech, and Zigamahornets (excuse spelling). Have also combined the Tektons with Velodyne sub with nice results. I fine them to be very flexible speakers. I have the 4.1's...in Ferrari Red. The Red makes all the difference IMHO.
