Harbeth 40.3xd vs Graham LS5/5

Can’t help with the comparison as I’ve only ever directly compared the 30.2 with Graham’s LS5/9 back to back in my house. Consistently preferred the Grahams in that case due to better treble extension and air.  That’s why I bought the LS5/5s, which I bought without an audition of either them or the 40.2/3s.  I am LOVING the LS5/5s but would probably feel similarly about the 40.2s if I’d gone with them.  
He’s a dealer for Graham, so he’s not exactly a neutral party here, but Erik from Gig Harbor Audio has heard the best of all Graham’s, Harbeths, and Spendors, and sold me the LS5/5s.  PM me for more info…

I recently dropped some money on a nice lampizator dac, absolare integrated amp, and some good cables, having first spent big money on the LS5/5s earlier this year. The LS5/5s are like a giant clear window into the rest of the system. You’ll enjoy them with merely very good gear like I did for a while, but they are almost overwhelmingly invisible and real with a clean very powerful signal in a good room. Truly full-range and very ‘alive’ without fatigue. No second guessing.

@echoz - you’ll probably love any of these speakers at this level of bbc monitor style and probably love the ATCs as well.  These are strong speakers that all will like and most will love.  No weaknesses of the smaller siblings, which are all great natural sounding monitors regardless.
