The Lyn is a wonderful guitar. I bought mine in the early days of the company (so mine was £1300 about 7 or 8 years ago) and I've honestly not played a better acoustic before or since. If you're more of a finger style player than a strummer I can't think of a nicer guitar, especially for the money. I'm very partial to a bit of John Renbourn and Bert Jansch and the Lyn really does cover that ground well even if my hands can't. :)
Strings wise I've found that the Elixir Polyweb sound really nice on mine. I tried the Nano web but they sounded a little too bright to my ears whereas the Polywebs had a lovely warm, full, balanced sound across the strings.
When I bought mine I tried every 12 fret 00 style guitar between £600 and £3000 and the Brook, to my ears, beat the lot hands down.
I still haven't worked out where it plugs into the amp yet though...
