I think the amp is part of the scala series, a 'lifestyle separates' series from the mid 90's. It's based on one of the older ES-series amps. I think you'll find the transformer even has 'ES' on it. There are a number of other components in the series, including some well regarded active speakers. The amp got good reviews when it came out, but apparently did not sell to well. Probably, as one review said, because the components were quite expensive, but together did a fairly good impression of a midi-system. I haven't heard it, but I imagine it's a good amp.
