Emotiva BasX A-100 Amplifier

Key Characteristics of the Emotiva BasX A-100 Optional High-Power Headphone Mode:  It includes an internal jumper to enable a higher-power mode for driving low-efficiency planar headphones, though this should be used with caution.  Dual Functionality:  The BasX A-100 serves as both a powerful stereo amplifier for speakers and a high-quality headphone amplifier.  Class AB Design:  It uses a traditional Class AB circuit, which is known for producing clean and detailed audio, rather than a digital switching design.  Compact Form Factor:  The amplifier is small, measuring 8.5 by 3.125 by 15 inches, and weighs just under 12 pounds, making it suitable for desktop use.  High Value:  It is frequently lauded as a fantastic value, offering impressive sound quality, build, and features for its modest price.  Limited Connectivity:  It features a single stereo RCA input, beefy speaker binding posts, and fixed-level RCA outputs, but it does not have a remote control.
