Although I haven’t listened to the Falcons, personally I’d try them over Harbeth 30.2. Just like Yogiboy, I’ve listened to all models in the Harbeth line including the 40.1 (not 40.2 though), all pre-XD models. They are surely nice but after experiencing the Graham which is another derivative of the BBC just like Spendor, Rogers, Falcon and Harbeth, I find that they offer something more unique. Or the Proac and Audio Note suggestions by Larryi.
As usual, try them and see for yourself as everyone prefers different things.
