On Elementary, Sherlock's electronics are definitely McIntosh, including (I think) a turntable. The floorstanding speakers are Energy CF-70 Towers, with a pair of Energy CB-10s or CB-20s on the bookshelves.

Energy makes good speakers for the money, but at $600-1000/pair, the CF-70s aren't in the same league as the line of 5-figure McIntosh components. Sherlock seems like the kind of guy who'd have something unusual, such as panel or horn speakers, but most viewers wouldn't know what they were.
