If you've got too much money and are looking for reckless ways to spend it, Sony has announced their new 'Premium Sound' Micro SDXC cards which are around 4-5 times more expensive than their regular Micro SDXC cards. What's the big difference? Well, apparently these 'Premium Sound' cards have 'less electrical noise' which has people puzzled since storage devices don't actually change the quality of the sound but simply store it. The debate is on over at PCWorld and you can make up your own decisions as to whether this is actually a premium product or a fancy marketing gimmick
Now, the idea of audiophiles obsessing over barely-perceptible details is nothing new. The speaker market is filled with products whose frequency response exceeds the 20 Hz to 20 kHz range of the human ear, and you can spend thousands of dollars on audio cables in pursuit of eliminating noise.
But while those expenses at least have some technical justifications behind them, the case for audiophile storage is flimsy at best..
