They do look fairly similar the power caps are laid out similarly, they both use discrete dual toroids, and the pre-amp section looks similar. They are not identical but you can tell that they are related in a Toronado and Eldorado kinda way. Though correct me if I'm wrong the Special edition HRU amp's listed are different internally as well as externally from the regular Human Reign series correct?
*This is all based on visuals so if a designer or engineer from SS want's to join in and tell me I'm wrong, I'm cool with that.*
