Tube amplifiers have long been a passion for audio purists and musicians who have cash to support the pricey habit. There's also the bonus of steampunk-esque styling that these exposed-component devices exude. This week, three lucky readers will get to warm up the sound of their digital tunes courtesy of Monoprice, an online bastion for affordable alternatives to costly electronics and cabling. This stereo tube amp system is a hybrid including vacuum tubes and solid state in one package. It offers an RCA line-in along with a toggle switch for playing tunes over Bluetooth 4.0. On top of the classic tube amp style and 25 watts-per-channel peak output, you get a pair of 5-inch 2-way bookshelf speakers and braided banana clip cables to complete the setup. All you need to do is head to the Rafflecopter widget below for up to three chances at winning one of these complete audio packages courtesy of Monoprice.

Winners: Congratulations to Eric M. of East Aurora, NY; Jerry F. of Cincinnati, OH and Matt A. of Georgetown, KY!
