You might consider a Belles amp. Perhaps the Soloist 1 integrated even. They have a full, tuneful and robust sound to me that would mate quite nice with Thiels. However, as a previous Thiel owner, I'd go with a solid state amp, think Levinson, Krell, Conrad Johnson, BAT, Classe or Belles. Then add a tube preamp which will help to flesh out the sound from the Thiels. As Thiel's Kathy Gornick was once quoted as saying, " I never heard a Thiel speaker that didn't sound better with a tube preamp." For cables, go Straightwire, Transparent or MIT. Keep us posted and enjoy your Thiels.....they're worth it. Best.
