Pretty much all headphones will benefit from connecting them to an amp. But when you get to the high end headphones, then an amp is needed to drive them. You also need them when using portable devices, since they tend to minimize sound output to save battery life. Click here for our Headphones Amp Buying Guide

An auto-lock protective circuit will turn the amplifier off automatically in the event of abnormal activity in order to protect your headphones and minimize the risk of hearing damage. The amplifier operates on a high-performance BL-5B Lithium battery that is easily replaceable. The battery provides approximately 10 hours of operation per charge, allowing you to listen all day. The amplifier has charging and power indicator LEDs to give you a visual cue of operation status. A charge priority function will cease operation while the amplifier is charging. Once the battery has been charged and the amplifier is unplugged, operation resumes.
Genuine State-of-the-art Headphone Amp Don't be fooled by its plain vanilla chassis. The unassuming-appearing Musical Fidelity V-CAN is a genuine state-of-the-art headphone amplifier. Most high quality headphones have impedance of around 30 Ohms. Yet almost all headphone amps have an output impedance between 50 and 100 ohms. Because of their high output impedance, these other amps cannot drive headphones properly. Any sound they produce through the headphones is necessarily colored by distortion and nonlinear frequency response. The V-CAN is quite different. Its output impedance is 5 ohms. This means it will drive any headphone available with ease. It will produce low distortion, ruler flat frequency response, and complete linearity. V-Series Components The V-LPS is part of Musical Fidelity's V-Series of components. The V-Series is a new, ultra-value, super-performance series, which offers incredible value for money. As a result of careful engineering, the V-Series has state-of-the-art, no compromise circuitry housed in a nicely finished but modest package. Typically, the V-Series has 60% to 70% of its cost in electronics. The quantity and quality of components in any of the V-Series is pretty well identical to those from high-end components costing ten times (or more) the price. The difference is that the V-Series is housed in nicely finished, economical metalwork as opposed to the kind of chassis that Musical Fidelity calls "bloated high-end excess."
The compact EF2A headphone amp from HiFiMan offers a USB input and built in DAC with Burr-Brown PCM2702 chipset for direct connection to your PC. Analog RCA inputs let you plug in a line level source, such as a CD player. A front panel button lets you toggle between inputs. "This $169 little dude will deliver performance of amps twice the price... and if looks are your thing, you'll certainly be the cool kid with one of the sexiest amps around," reports Unplggd online for March 22, 2010. The smooth and rich sound quality is thanks to a vacuum tube output stage using two Chinese 6J1 tubes. The outboard power supply contributes to the quiet performance of the circuitry.
