Did you ever do a direct comparo between the C225 and the DB359? I love the Aguilar's tone but the size, shape and (with 30 lb case) weight make for an awful lot of trouble - and take up a lot of space in my truck.
I spent a good amount of time A/B'ing the two. They are different animals, the most obvious difference is that the C225 is louder, by a pretty big margin, maybe a little brighter and certainly stronger on the bottom.
I think it's probably the transformers. To be fair, it's not really a heads up comparo as far as volume; the Reeves "225"
actually outputs about 260 watts at 5% THD.
Both are real clean, both have gobs of headroom. The Aggie is more
controlled sounding, certainly a more modern, sophisticated circuit, an
excellent amp to be sure. Probably more versatile, but the Reeves just seems bigger and bolder overall, a little more raw. As you touched on, the Aggie is a "unique" shape, more cumbersome IMO than the traditional "amp head" size of the Reeves IMO; but neither one is really "portable".
