We've seen acoustic iDevice docks before, but Japanese manufacturer Pleiades has gone a little nuts with the horn. The Trumstand, as it's called, features an acoustic amplifier made of brass, with the sound channel elongated into an "S" because it apparently increases the bass. (Tough to tell from the wonky translation I'm going through here.) One version is gold-plated, another plated in sterling silver.
There's no doubt that it's beautiful, but I have mixed feelings about this product: Does it make sense to make something labor-intensive—well, CNC-intensive, anyway—out of fine metal when the object it supports will likely be obsolete in a year or two? Still, I've gotta admit, I am dying to hear how this thing sounds.
