Tubes for CJ Premier 16LS

Can someone with experiance with this preamp recommend some good tubes? Should I stick with what CJ has to offer or try
something different? Also, where is a good source for tubes? Thank you.
Brandon- if you run a search on tubes or tube rolling, you will find extensive discussion of this issue, esp. with respect to people's experience with various suppliers.
