I just received my new Sierra-1s in dark cherry gloss today. When ordering I was torn between the natural and this finish. After unpacking these I'm very satisfied with my choice-simply gorgeous. I've been listening to music for about 3 hours now (at lower volumes of course for break-in). I've pretty much run them through the gamut.
Miles Davis-Kind of Blue
Mark Lanegan-Whiskey for the Holy Ghost
Nine Inch Nails-The Fragile
Sasha-Airdrawndagger
Dvorak-Cello Concert0 (Mtislav Rostropovich, cello; Herbert von Karajan, conductor-1969)
TV on the Radio-Nine Types of Light
Of Montreal-EP
Gorillaz-Plastic Beach
The bass is pretty amazing. These are simply the best sounding speakers I've had. Glad I saved up for them. More thoughts to follow after break-in.
