QuoteOpinions differ as to the quality of JB3......
I must admit that I wasn't so sure about the jb3 until I held one in my hand and ran one at a show. It is a great piece of equipment and I have been very pleased with the results.
as far as quality of sound.... that would only be a concern if the jb3 was doing the a > d. then see brian's comp. If you are going digital in, the integrity of the bitsream is the same.
do yourself a favor and buy one. If you decide you don't like it, I'm sure you'll have no trouble finding a buyer.
