Long time audiophile, this was my first entry into tube amps. These amps pair quite will with my field coil speakers. These amps expand the soundstage, bass is full and rich, vocals have a weighty presence that invites one deeper into the music, which is what it's all about. I am very satisfied with my purchase.
