The Cary Audio SL-100 dual-mono solid state preamplifier combines the attributes of low noise, low distortion and ease of use via dual power supplies and dual mono circuitry.

It features a selection of inputs and outputs including balanced (XLR) and unbalanced single-ended (RCA), as well as a front-panel LED window complete with four brightness presets, including an "off" option.

Autonomic announces the Mirage MMS-2A, a music player the company claims delivers reference quality high-resolution audio through 3 independent streams to a multi-room system with up to 96 zones.

It features a fanless, passive cooling design with storage handled by a 128GB SSD (expandable via USB or NAS) and a new generation of the Autonomic cloud-based media server. Content playback support is put to 24-bit/96kHz.

The player also connects to a number of popular streaming services, namely Pandora, SiriusXM, Spotify, Slacker, Rhapsody and TuneIn, and carries two Airplay receivers (1 per stream).

Extron Electronics introduces the Extron XTRA Series XPA 1002-70V and XPA 1002-100V, half rack 1U, convection cooled power amplifiers delivering two channels of 100 watts rms for 70 volt and 100 volt distributed speakers.

These professional grade amplifiers feature a 100 dB signal-to-noise ratio with 0.1% THD+N specifications. The XPA 1002-70V and XPA 1002-100V are ENERGY STAR qualified amplifiers with an Extron exclusive, highly efficient, advanced Class D amplifier design.

They also feature patented CDRS - Class D Ripple Suppression technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. The XPA 1002-70V and XPA 1002-100V are housed in half rack width metal enclosures, conserving rack space and weighing only 2.5 lbs (1.1 kg). The Extron-exclusive, high efficiency design generates very little heat and allows the amplifiers to be convection cooled.

The HA-P50 is the first portable headphone amplifier from TEAC with a built-in 24bit/96kHz USB DAC, providing high-resolution audio from devices such as iPhones, Android smartphones and PCs.

It receives digital audio via USB (up to 16bit/44.1kHz) and the built-in BurrBrown PCM5102 DAC processes it to a maximum of 24bit/96kHz  with minimal sound degradation and maximum fidelity, at least according to the company.

A high/low gain selectors matches output gain with headphone impedance, allowing the 2 x 160mW power amp to drive 600ohm headphones at full power, while a combined digital input and analog audio in terminal self-detects incoming signals.

Denon launches HEOS-- a wireless multi-room audio portfolio claiming to bring Denon-quality audio to any (or all) rooms via the combination of wireless speakers and mobile device app.
