Looking for Alternative Preamp to Blue Circle BC3

I've lived with a Blue Circle BC3 preamp for a while now and I have only good things to say about it. The trouble is, my wife is intimidated by the dual volume controls and after much discussion I've agreed to start exploring alternatives. I want similar performance, my wife wants a single volume control (to her credit, she appreciates the quality of the BC preamp and also wants to maintain this level of standard). What preamps should I be looking into? The Herron preamp and the Ayre preamps appear to be viable options. What else would you recommend? Thanks for your input.
