Graham ls5/9 vs Harbeth M30.1

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.

my sister and i demoed both with her dealer in Michigan.  both lovely but the Graham blew us away.

they were set up with NAIM electronics.

But is is right compare It with 30.1??
Or is better compare with shl5+ ??

Good question, have not heard any other Harbeth speaker
but maybe the Graham sits between the two!
I felt that the Graham had deeper bass than the 30.1
But I heard the 30.1 in an unfamiliar room, and not a good room at that. 
I listen mostly near field to nullify the room as best, but can not be 100% sure if the bass would be better in my living room.
The reason I like the Graham better, is not the bass, but the difference in the midrange region.
I dont think you can go wrong with either speaker, if you like their sound signature they will provide you with many staggering listening experiences. Enjoy your music, whichever one you chose.

If you are looking into Accuphase, go for the E470 over the E600 - I have Graham LS5/9 and Devore O/96. I run the very efficient Devore with the E600 and it is a perfect match; the LS5/9 sound good but I feel they would benefit from more power. I feel the E470 would match much better; the E270 may even work. Tonality wise the LS5/9 should work wonderfully with the Accuphase.
