What we liked
- + Three switchable gain modes let you match different MM cartridges.
- + Compatible with 6K4, 6J1, 6J4, GE5654 and 6AK5 tubes for tube rolling.
- + Includes two tubes, an RCA cable and a power adaptor.
Trade-offs
- - It supports MM cartridges only, with no MC input listed, so MC owners need a different stage.
- - It is a small, entry-level tube stage, so expect modest build compared with larger units.
