Graham ls5/9 vs Harbeth M30.1

A bit difficult to answer, I audition the 30.1 in a store, but bought the Graham Audio LS 5/9 unheard! 
I like the Graham’s better, hearing the Harbeths in the store was a revelation, but also too much of everything, well the midrange.
I find the Graham’s to be more balanced, they let you look into the recording, while the Harbeth project the sound more towards you, especially the midrange, which I found to be a bit too much, this is just my opinion and if you are able to hear both, you maybe will have totally different impression.
One thing for sure these 5/9s I expect to keep for the rest of my life, they are that good.

I'm not able to hear both
I tryed in a shop Graham and i liked ItCan i ask which amp do you use whith It?

I use a solid state amp 100w powerful, but a bit lean and I also use an other solid state that has tubes in the pre amp section, about 150w it is more sweet sounding, but could have some more detail.
The plan is to get me a better amp, been looking at Accuphase, Luxman and PS Audio.
