I have a friend who did the modifications to either an LS16 or LS 25 (sorry can't remember which model), I was quite surprized, the results were stunning.
I have an LS5 which I feel is outside of the Ref2 the best Arc preamp that I have heard. I am definitely going to do a Great Northern Sounds modification to it.
Steve Huntley used to work for Audio Research and is very helpful at evaluating the sonic benefits of particular Arc pieces. He was quite informative on sonic characteristics of the various pieces in his e-mail correspondence with me. You could ask him whether to modify the LS 16 or upgrade and modify another Arc piece.
hope that helps
