Do you mind sharing where you got your Harbeths and Grahams from? I am assuming you are in the USA, but if you might be in Europe then it won't really mean anything to me. I need to touch base with the USA distro of Graham again and see how things are going. I miss working with the dealer network! To my ears the LS5/9 had a more satiable tonality and detail retrieval. Sound staging was better, in width and depth, and to that degree the micro dynamics were better with the LS5/9. Certainly, your mileage may vary and I am happy to hear that you will be comparing them directly side by side with the SHL5+. If you're going to invest that kind of money into speakers it's vital that you make your own decision. If you can, try the Chartwell LS3/5 and compare it with the Harbeth P3ESR. The difference is not subtle.
