U can try to use AD843 for the preamp, it is a good preamp. This IC equal to OPA627(which expensive). Or if u want to build low cost preamp with a reasonable price but have a good sound too, u can use OPA2134/AD823. Take a look at Rod Elliot websites, u can find a lot of preamp in there.
Btw, i'm also confused to decided which preamp should i built for my GC
But, i prefer to build tube preamp with 5678 but i will be an expensive project.
