Great speakers are a long-term investment. The Griffin Twenty Digital Audio Amplifier lets you add Bluetooth connectivity and extra decibels to durable sound for $120 shipped at 9to5Toys Specials.

Unlike amplifiers of old, the Twenty uses high quality AAC and aptX streaming codecs to pump up the volume without any sound degradation or distortion. The music is fed out through regular left and right audio outputs, and there’s an additional jack for connecting to a powered sub-woofer.

You can stream music from most Bluetooth-enabled phones, tablets and PCs, and a TOSLINK cable is included for bringing sound from an audio-visual device, such as a games console, or an Apple TV. The Twenty has a wireless range of 10 meters (approx. 32 feet), and it can kick out 20 watts per channel.
