Are you a fan of using Google's Cast tech, AirPlay or Spotify Connect to handle your wireless speaker duties? Well, Sony announced a trio of audio gadgets that play nice with all three. Continuing its affinity for alphanumeric product names, the company's SRS-X77, SRS-X88 and SRS-X99 speakers also feature a Sonos-like multi-room experience thanks to the Song Pal app. The pricier two of the lot, the SRS-X88 and SRS-X99, add in support for high-resolution audio via USB and a thumb drive or direct connection to your computer. If you prefer to go that route, you can expect compatibility with AAC, FLAC, WAV and other file formats that offer better sound quality over a regular ol' MP3. The SRS-X88 and SRS-X99 also pack in a S-Master HX digital amplifier and LDAC tech that's said to keep Bluetooth streams sounding top notch (from compatible devices, natch). The difference main between the two? Power. The SRS-X88 has five speakers at 90 watts and the SRS-X99 houses seven with 154 watts. I guess it really just depends on how loud you want to blast "Hells Bells."
