Here at the ListenUp blog, we’d like to think of ourselves as the ultimate oracle of audio/video information. But we’re happy to admit that the ListenUp team has another great way to deliver news and deals, via our e-mail newsletter. If you’re already on the list, you know the drill: twice a month you get first crack at the best deals (like this iTannoy speaker system for you iPod, just $129). You say you’re not on the list? Here’s where to sign up.
