Get a used Alesis Masterlink or some other real recorder. It has digital inputs. Assuming you don’t have a DAW. Otherwise you are going to a lot of stress over something not that difficult. I own a lot of expensive mic preamps. I own a GLD. If I were doing what you are I would personally use one of the pres. I don’t think I would be afraid to use the GLD. I just have done a comparison. Anything in the process can be a weak link. You have to decide that or get help deciding.
