Graham ls5/9 vs Harbeth M30.1

The plan is to get me a better amp, been looking at Accuphase, Luxman and PS Audio.

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. 

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

While I did not hear the Graham side by side to Harbeths I think the review does an accurate job describing the differences and aligns with my impressions
