The SC-57 boasts a new amplifier, networking capabilities, and DTS Neo: X compatibility.
Pioneer has launched a pair of new receivers - the SC-55 and the SC-57, the latter of which is the flagship for the Elite line. The receivers are nearly identical in most respects, but the SC-57 boasts THX Ultra 2 Plus certification while the SC-55 does not.
Both receivers benefit from the brand new D3 amplifier architecture. This new tech allows the receivers to be more power efficient, and disperse heat better. You'll also find that the SC-55 and SC-57 have lower total harmonic distortion than previous modes, thanks in part to a new signal path that's a third shorter than the 2010 models.
Pioneer has packed AirPlay into its new receivers, which is becoming a regular if not required feature for new components. It also utilizes Air Jam, which lets you connect as many as four Bluetooth devices. You'll have to purchase Pioneer's Bluetooth adapter of course.
The SC-55 and SC-57, both of which offer Marvell Qdeo processing, are available now through authorized dealers. The 55 comes in at $1,600 while the 57 carries an MSRP of $2,000.
