The VAC Sigma 170i iQ did well across criteria typically associated with tube amps, and more: sweet treble, excellent midrange, musicality, bloom. Timbres were more natural than warm. Bass was substantial, with good definition. The VAC amp seemed more powerful than its rating suggests, and often delivered solid attacks. It’s not inexpensive, but it is luxurious, and all its details are well-considered. It was a pleasure to set up and to use. It’s built by hand and meant to last at least one lifetime. There is value here.
