There was a pair of SHL5's being driven by an imported transformer coupled valve amp with little to no bass damping and used in a room far too boomy for them - not yours.

With deepest respect and totally academic now, I worry a bit when I read that the SHL5 has a forward midrange! This always rings alarm bells that something further upstream, or the room, isn't right somehow (I'm pragmatic and work from decades of setup/installation exeriences here). If anything, the balance of this range of speakers, certainly the domestic models, is designed to be slightly on the warm side to encourage and support low level listening which is part of the wonderful vibe I have for them, since having to turn the volume up to get the detail is always indicative of a mismatch or problem somewhere. Seriously Paul, if you found the SHL5 mid-forward, then you really wouldn't like any of the smaller pro-active models out there, since many still seem to exhibit the inverted "V" response to magnify the glare frequencies and allow use on desktops.

I'm doing it again, sorry! I know Alan personally, am still in touch with him from time to time, and sold these speakers' ancestors from the very start in 1977 as well as having regular exposure to the current ones. I suppose I'm as totally commited, positive and fond of the range as Marco is of his Tannoys and I get too involved if there's an issue

If you haven't got this already, please try to get the ep "Mindworks" by Sam Brown. The Turnberry's won't have an issue with this disc at all methinks, but if there's any midband or crossover problem with the speakers or system, you'll hear it in seconds (ask hifi dave or Alex_UK, I've tortured them with these tracks on AVI speakers a couple of times...) since Sam's voice will make you wince if there's an issue, but not if the speakers are properly balanced and their interface with the room interface is a good one.
