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.
