High fidelity and Bluetooth generally won’t be found in the same sentence. And it’s still the exception rather than the rule — but the advent of AptX, an audio codec for Bluetooth that lets listeners stream CD-quality lossless tracks to their speakers wirelessly, has meant that renowned audiophile brands — and a few upstarts — are at last getting into the post-dock portable speaker game. Most new phones and tablets, especially Android ones, are AptX enabled. iOS devices are not, but that’s what AirPlay, which works over wi-fi and can stream lossless audio anyway, is for (and for iOS or Mac devices only).
Hi-fi Bluetooth speakers still take a backseat to a bonafide stereo system — and even your stereo you can be made AptX-compatible with a simple Mass Fidelity Bluetooth DAC ($250) — but you no longer have to go with a dock-based “wired” system to get great results in a portable package. Using a variety of music genres in lossless format from Tidal HiFi, we tested out 10 different speakers, keeping in mind they needed to be portable enough to take from room to room, with a few portable enough for taking on trips. All of them are AptX enabled, with some able to handle Airplay, too. We narrowed it down to five speakers we liked best, for different types of scenarios and needs.
Peachtree Audio Deepblue2

Best Stereo Replacement: It’s lacking in mainstream brand recognition, but that’s about it. The Deepblue2 is a classy, understated affair, offering up a five-driver system with two one-inch soft-dome tweeters, a pair of three-inch midrange drivers, and a six-inch bass driver in a separate sealed enclosure. It also taps five separate Class D amplifiers for a total of 440 watts, ensuring that it’ll fill even the largest of rooms. Bluetooth 4.0 and AptX support are included, as is a full-function IR remote. At 13.5 pounds, it isn’t the most mobile of devices, but stereos rarely need to be relocated.
