Sonically, with good 6550's the classic 60 is far superior to the rogue. Too many owners of the Classic 60 settled for the sound they got using the stock 6550's from ARC. With better tubes this little amp was wonderful. If you are looking for a recommendation on which amp to purchase I would have to recommend the Rogue not because of sound quality but serviceability. The Classic 60 is about 20 years old now and parts for repair (it's a tube/transistor hybrid) will become scarce if they are not already, while the Rogue is a relatively new amp.
