What's your guilty pleasure?
multiples
main one is I'm an "audiophile" collect vinyls, have high notch speakers with special "DAC's" for all my devices (BlueRay player, music, etc) Not for loud listening but to be able to transmit the pure appropriate format and even a monthly subscription for also streaming in HiRes. Even when I'm out I carry an AMP external DAC also for my cellphone to convert it into a powerhouse even in the car. The better the audio quality the softer/lower the sound is, but the file size can be thousand times higher than a regular mp3.
