I had a DRRI and thought it sounded great. Then I got a Silverface DR and it just sounded so much better. The same when I got a Blackface DR. The DRRI just couldn't match them. I'm sure a lot of it has to do with the age of the speaker and components. I got a Brownface DR and then I built a handwired clone. The clone sounded real close, but just didn't quite have the depth or richness of tone as the original. I'm hoping getting some hours of playing time will get the clone to where the original is. If you are doing your own amp work; there is no comparison, handwired is the only way to go.
