That's all well and good for the 510's. I'd love to have one for my E9/808D2.
I've got too much invested to change now, and they've been working well for me.
Have you considered an adapter, Blue? I have all 801 stuff so I tried a 510 to 801 adapter and it worked like a charm. Then you won't have to change any of your gear.
On another note....I'm just loving this LS! Got another one coming too
