The Harrods TV and hi-fi department is basically a Sevenoaks franchise, who are in their own right Meridian dealers, but the Harrods set up has never stocked M products and has a complete Linn bias).
Its possibly a few 'shops' rolled into one. 3 years back when I bought my Loewe TV, the Linn/Loewe was certainly an entity in its own right, and I think the Sony 'shop' that divided Linn/Loewe from the main shop floor was also autonomous. However, it may have changed now as last time I visited, Linn/Loewe were part of the main shop floor and there was less apparent segregation. And more importantly, gone was that huge huge huge holographic/glass TV.
