I owned one for a couple of years. Very balanced and smooth tone but not overly warmish (by early 90's standard). Tonally it was much like the SP10 pre-amp that came out at the same time. Soundwise it was a very good amp.Its got a lot of tubes in it and frankly its hard to maintain. Biasing the tubes is difficult and time consuming. Additionally there are no fuses to protect the bias resistors if a tube shorts out - unless you are a good tech yourself you'll have to haul it into the shop for repairs.
