Whether you want to use some soft jazz to enrich a dinner party, or just kick out the hip-hop jams solo-style on a Tuesday night, there's no shortage of wireless music players you can enlist. But you don't need to buy a dedicated speaker system. Here are two audio products that let you play streaming music on your existing audio hardware---even on speakers that were assembled during the Carter administration.
The Griffin Twenty is a great-sounding 20-watt amp that you control over Bluetooth. Any audio stored on or streamed to your phone or laptop can be sent to Griffin's sleek-looking player. But the speakers are up to you---the amp has two traditional speaker posts on the back, so you can hook up any pair of passive stereo speakers. It's the perfect Bluetooth solution for the person who has a pair (or three) of vintage speakers sitting unused in the basement. Analog inputs on the back let you hook up your Rega turntable or Marantz cassette deck.
The Gramofon is something entirely different---a streaming "receiver" of sorts that you hook up to an existing stereo. It turns any sound system in your home into a Spotify station. After a quick setup to get the Gramofon onto your home Wi-Fi, you can send Spotify tracks (or streams from Rhapsody, TuneIn, and other services) to the device wirelessly from any smartphone. Group a few of them together for multi-room audio. Best of all, any of your friends who stop by can control it from their phones too. It turns any gathering into a round-robin DJ tournament.
