Harbeth vs Graham audio

Graham make the real BBC monitors in terms of the LS3/5a (similar to P3) and the LS5/9 (similar to M30).  It depends on whether you care about having an actual BBC monitor or the Harbeth versions which to my hears are better for a home based system.  Tube amps or big high end Japanese amps work well for all.  The Classic Spendors are a bit warmer and less open (like my old Rogers speakers) and then you also have ProAc which offers nearly BBC levels of natural midrange but is a more dynamic and open sounding speaker. 

Keep in mind all but the ProAcs were designed for voice and classical/instrumental music primarily.  If you listen to a lot of rock, go with ProAc or one of the more modern Spendor designs. For classical or jazz, they will all sound great. 

I own the Graham Chartwell LS3/5’s. I find them very addictive. I don’t listen at ear bleed levels,and I have a small listening room. I also listen to anything from metal to soft jazz. To my ears,and my tastes,these do everything very well. A disclaimer though,I’ve never had the pleasure of hearing Harbeths. 

I own a pair of Harbeth 30.1's and a pair of Spendor S3/5's. While I like the Harbeths much better over all, male vocals sound much more lifelike to me through the Spendors. I haven't heard any Graham speakers.

I am grateful to everyone for the advice, you helped me a lot. as I understand it, Graham audio is still a wild card, and therefore statistical comparisons are still difficult.

No mention of ATC ? Spendor BC 1? 
I auditioned the Harbeth P3 last week.
With all the recent Hoopla I was expecting more.
