If they are truly the same price, get the 1070. It has the newer styling, and has the ability to turn on/off via a 12V connection on the back (so you can turn it on and off via the pre-amp's remote).
OTOH, I have been told that these amps are internally identical, and they sure sound that way to me. If you can save a couple hundred with the RB-981 (and don't care about the styling or the remote turn off/on), then go that route. The 981 is discontinued, of course, so it should be cheaper than the still-current 1070.
I'm not familiar with the 908.
