Elf1: "Most" balanced outputs almost always double the output voltage. This is a good thing. Eliminating your preamp, if the preamp is in good internal condition, will sometimes make the final sound leaner and thinner. I would invest in a comparable preamp with balanced connectors. I think u will hear an improvement in your sound, i.e., a fuller more gutsy sound, while having more diversification at the same time.
Should I eliminate my preamp?
I have been using my Audio Research tube preamp and Bryston amp to drive Magnepan speakers for years. Recently I added a Oppo blue ray player to my system and connected directly to my amp using the balance cables. The reason was to eliminate the signal having to go through another piece of equipment before it hits the amp. Am I wrong or what am I missing?
