I have a DD-, I like it, and although I have only used it once to tune my system and have had it over a year I don't regret purchasing it.
I am intrigued by the DD-1+ but am on the fence about making the purchase... $250. I asked about a trade in program when they first came out but I don't think there is one. Yeah I could sell my DD-1 but it's signed by Meade and I really don't want to try to sell it. I am not one of the lucky ones that can just drop hundreds of dollars on a new gadget whenever they want to. If I was in that position i would own all of the SMD tools and meters. I could buy it on credit but I am unemployed right now and that would be against my better judgement, although I could probably be convinced
I watched Steve's YouTube video about the DD-1+, searched the forum for topics, and even downloaded the owners manual and am still left with questions about exactly how gain overlap compares to using the various DD-1 tracks. Say for example you have a DD-1+ and you set the gain overlap to 10db, how does that differ from just having the DD-1 and using the -10db track?
Also, how do you know what type of overlap to use when you have fully variable adjustment from 0-15db?
Thanks to any and all with input.
