Practical Devices Corporation is pleased to release the XM5 Portable headphone amp.  AFAIK, this amp represents the most features ever squeezed into a portable.  Strong, clean, smooth, unsurpassed sound quality is made possible by the XM5's four-chip amp/buffer system: a two-chip ultra-low-distortion FET amplification stage, mated to separate two-chip output buffering, all in a monoblock configuration.  The four gold-plated sockets allow for rolling amp chips and/or output buffers to exactly suit your taste.  Available in black faceplate on black case, or blue faceplate on silver case. Key Features: USB DAC (44.1/48kHz) Buffered Output Monoblock channel configuration Quad gold sockets, for rolling amps and buffers Switches for: Bass, Treble, +10dB Gain Boost, CrossFeed, 75Ω output impedence, and USB/Line-In select Variable Active CrossFeed Auto power-off Robust, all-aluminum construction +103dB SNR .001% THD Low-battery indicator Lithium-Ion FastChargeTM 1-hour no-hassle universal charger Intelligent Microprocessor control Looks, feels, and sounds spectacular and lots lots more.
