My opinion only, of course: They still sound as good as they ever did. I've got one module that is directly overlapped: The Judge. It is a single-channel Friedman BE with a saturation switch. Compared to the Synergy BE, it sounds just about the identical- maybe a little darker, though that could be the tubes. Great module and still a favorite. Amusingly, I found it via the Fractal BE model. I had to sell my Fractal to pay down divorce debt. When I asked what could get that sound, "The Judge" was recommended and it did not disappoint. I've got another module that has no peer that I've found so far: Brahma. Desert. Island. Module. It just sounds like the sound of rock guitar in my head. I need to ask Dave Friedman if he can turn a Synergy module into a Brahma somehow but he's got to finish turning my Plexi into a Brahma first. But if you're a brootalz type of guy, this module would suck to you. It's an 80's rock machine. A lot probably comes down to taste and application. As a Fractal user, I've never felt that Fractal said that the older model is no good anymore. I think it would be out of character because they are proud of what they built before. Obviously, they want to sell new units and the new units get the development so that the older units fall behind in terms of features, but they still work and sound great. It may be easier on the new ones to get your sound but the old ones still hold up fine. The newer Synergy modules are sort of like that. They are adding cool useful features that you could do without but would generally appreciate. Look at all the switching goodies on the Ecstasy and Deliverance modules. The older Randall modules never had anything more than a bright switch. (OK, 1086 had the useless scoop switch) I think the Synergy Ecstasy module is much better than the old Randall XTC module. I don't have one anymore but I remember the XTC module being pretty decent. Like the Synergy Ecstasy, it just wasn't my sound. I'm not sure if this helps, but my two cents.
