Dd1 vs O scope
Since I don’t trust my ears, I’m considering a meter to determine safe max on outputs. I’ve seen some reviews on other forums about handheld scopes that work well that are priced about the same as a dd1. The scopes also display volts to know where you are at in the same step.
Does anyone have any experience with these can shed light on pros and cons of either unit?

I've never used the DD1 before, but I have access to multiple scopes (lab, repair and analytical quality) at work. A couple of years ago I forked over some $ for a hand held TPI 440 combo meter that includes o-scope function. I've used it on bike audio a bit, but the main reason I bought it was flexibility for other electronics and electrical work I do. I liked the one I bought for myself so much that we have purchased one for use here at my work as well (electronics repair). It's quite bit handier than the ones we have to roll around on a cart 
The TPI units have a very good warranty (3 years on most of them) and I've even had to use it once. They repaired the charging circuit on the first one I bought under warranty right at the end of the warranty period and with me unable to find my original purchase receipt.
With that being said, most all of the experts will tell you that any scientific method only puts you in the ball park and the final tune for best results is obtained by ear............ Who am I to argue?
