Tannoy Prestige Turnberry GR Limited Edition or ProAc D 30 R o RS


I’ve owned a pair of Tannoy Cheviot II for 28 years... Now, I would like to replace them either with a more recent Tannoy model (i.e. Prestige Turnberry GR Limited Edition) or with ProAc D 30 R o RS.
My amplifier is an old Exposure Super XV, which I intend to retire as well.
Which of the two should I go for?

I would be particularly pleased to hear akg_ca’s opinion.
Thank you all for your contributions.

Hi Steve,
I wish to inform you that I made a big mistake. Eager to radically change, reluctant to spend too much, influenced by a number of enthusiastic reviews, I eventually purchased a pair of Spendor D7. Very appealing at first, after a while they proved to be lean and almost inexpressive - I dare not imagine that the amplifier (Exposure 3010S2 Pre + 2Mono Power), new as well, might contribute to such a disappointing outcome...
So I regret I didn't go for the Tannoy Prestige Turnberry GR Limited Edition, which are no more available. I could fall back on the Turnberry standard or opt for the updated version of my old Cheviot, so-called Legacy Cheviot. Did you happen to listen to any of them?
Best Regards
Paolo 
I would guess that Cheviot is a better choice than either Turnberry or  ProAc D 30 R o RS. Why change?
I bought the new Cheviot a couple months ago. Sublime. Super smooth. It's like they're designed for jazz. 
I appreciate this thread because I'm considering dual concentric speakers. Can anyone talk about how they would image and present the music differently than a more narrow, inert tower design? SO mush of what we her is in the design of the box.  I know Tannoy is very particular about box construction, so how dos this effect image? Is it very dimensional?  Some say image isn't important and that's fine, but they will never be in my living room either. 
FWIW I had Proac Response R2's and found them to be lively with depth, without getting bright. I've never heard the D30.
