Tannoy Westminster GR or SE?

I've been reading quite a lot about the Westminsters and I happen to have an opportunity to purchase either the SE as the GR versions, at the same price, but won't have a chance to listen to them before deciding.

I love the paper cone speakers, like the Glenair, and got very anxious when hearing that the GR model has some new synthetic fibers added to the paper cones, it really gave me the chills!

I use the Audio Note Ongaku UK and the listening room is 31x20x11 feet. I listen mostly to symphonic music and jazz.

Has anyone listened to both SE and GR and could advise me which way I should go?

Thanks!
