Following up on my previous post, based on the comments by Victor of BAT in this thread it appears that the concern I mentioned about possibly losing 75% of the amp's power capability when providing it with a single-ended input is not applicable to his designs, as they use differential stages, rather than independent paths for the two signal polarities.
However, if you are providing the amp with a single-ended input via an adapter or adapter cable, you are reducing gain by 6 db, and you are most likely compromising sonics to a perceptible degree in several ways. The best way of interfacing your preamp and amp would be with a Jensen transformer, such as their model PI-2RX (similar to the model PI-2XX shown near the bottom of this page, except with RCA input connectors). Here is the datasheet. That model would be located close to the amp, and connected to the amp via what must be a short XLR cable, and connected to the preamp with whatever length of RCA cable is required.
You should consult with Jensen by phone before finalizing selection of a particular model, though.
