Just spoken with RS, told him it lacks a bit of punch. He said it is because it isn't run in yet. The speaker cone inside the Grados is still stiff which doesn't allow the cone to move a freely as it should. He's advised me to leave them on for a few days, see if things inprove.
My SR80s are now 8 years old and do bass that is bigger in everyway than my less than a year old PX200s. I cant particularly remember any great running in with the Grados and I definitely do not remember returning to them at any point and thinking, wow the sound has improved here. Fair enough leave them for a week and get as many hours on them as possible, but sorry, I have my doubts.

I also asked about a headphone pre-amp, he asked what system I have, he said it shouldn't need an external amp. My Arc, according to him should be good enough to make the Grados sing.....and so the question continues.
The Grados are easy to drive and I am sure that that is right. A headphone amp comes into its own for regular headphone listening and difficult to drive headphones.
I'm not sure about the running in malarky, either. I'm a little naive with headphones due to the fact that these Grados are the first ones I've ever bought (even though I've being buying and listening to hi-fis for over 30 years). I'll let'em run for a few days and see whether there is any change.
