Please do not ask us to make that determination. It is a personal and subjective decision which is up to you based upon your requirements and your taste. We do not offer advice (this type of advice is time consuming, not included in the cost of the transfer and may be perceived as a conflict of interest if we recommend Restoration). Also, we do not want to assume responsibility that we have made the wrong recommendation. That is exactly why we are offering an option for ordering BOTH versions (Transfer Only AND Transfer with Sound Restoration). When in doubt, order BOTH versions.
"Dear Dr Coban: I received the CD that you made from my very old (40+ years) tape of a live concert. I want to thank you for a superb job and an excellent recovery of what I thought was a lost cause. Thanks again"
