As handsome as ever, the new-look version of Unison Research’s single-ended class-A S6 integrated amp ($4995) is less swoopy and more techie, the semi-matte-black upper section contrasting nicely with the orange woodwork. The tube array includes three EL34s and an ECC82/12AU7 per channel, for an output of around 35Wpc. The unit accepts five line-level sources.
