Our take on the Musical Fidelity M1HPAP

by Dave Bar

Why buy a headphone amp?

High-performance headphones need high-quality amplification to perform up to their full potential. If you connect them directly to the headphone jack on your computer, iPod®, or stereo receiver, you may be disappointed. A separate headphone amplifier sends a stronger, cleaner signal to your headphones.

When it comes to high-end headphone sound, most receivers can't do jack!

If you love your headphones, don't feed them junk. Instead, use Musical Fidelity's M1HPAP headphone amplifier to serve up wholesome, high-fidelity sound that will bring them roaring to life. The M1HPAP makes tunes through flow through your headphones with remarkable warmth, clarity and detail. This beefy little amp can drive even the best cans with unquestioning authority, for a listening experience that goes far beyond what your receiver's or CD player's headphone jack can provide. The M1HPAP also features a USB input to handle digital audio from your computer. This elegantly compact component will bring deeper enjoyment to your music listening whether it's at the office or kicking back at home.

Super-clean Class A amplification

The M1HPAP energizes your music using pure Class A amplification — an amp design long valued by audiophiles for its tonal purity and open sound. A hefty, built-in power supply ensures rock-steady performance and powerful dynamics that don't bog down when the going gets tough. The M1HPAP's remarkably low output impedance of less than one ohm also means it's capable of driving virtually any headphone with complete linearity and low distortion. All of this goodness is wrapped up in a beautifully built half-width component you'll be proud to display on your shelf.

Versatile connections for your system

In addition to its outstanding performance with headphones, the M1HPAP can also double as a preamp to create a simple, high-quality stereo system. You can connect your PC to its USB port, and up to two audio components to the RCA inputs. Then connect the Musical Fidelity's preamp outputs to the amp and speakers of your choice. A front-panel switch lets you choose between sources, while the volume control adjusts signal output to your preferred listening levels — a nice alternative when you want the music to fill your room, not just your head.

Features

Overview: The Musical Fidelity M1HPAP Class A headphone amplifier provides a rich, full, smooth sound with greater bottom end extension. The M1HPAP consists of a pure Class A circuit giving exceptional performance into virtually any impedance headphone. It features two line-level inputs as well as a USB input, and a line-level output. It also features two headphone outputs and a set of volume-controlled outputs to enable use as a preamplifier. In addition, the headphone amplifier is equipped with a robust power supply circuit for consistent performance and reliability. Overall all, the Musical Fidelity headphone amplifier offers astounding imaging, detail, and transparency to all types of music exactly as the artist originally intended.

Class A Headphone Amp: The Musical Fidelity M1HPAP utilizes a pure Class A headphone amplifier for incredibly low distortion (less than .0008%), an extremely high signal-to-noise ratio (109db), and a ruler-flat frequency response (15-75,000Hz).

Low Output Impedance: The Musical Fidelity M1HPAP has a very low output impedance (below 1-ohm). A headphone amplifier's output impedance is usually ignored, but a very important measurement. The M1HPAP's extraordinary low output impedance means that it can drive any headphone with complete linearity and low distortion. The vast majority of competitive headphone amplifiers cannot do this because they have much higher output impedance.

Note: Most high-quality headphones have impedance of around 30 Ohms. Almost all headphone amps have an output impedance between 50 and 100 Ohms. Because of their high output impedance they cannot drive headphones properly. Any sound they produce through the headphones is colored, with distortion, and non-linear frequency response.

Volume Control: The Musical Fidelity M1HPAP headphone amplifier's front-panel volume control knob lets you adjust your headphone's volume to a comfortable listening level.

Dual Headphone Outputs: The Musical Fidelity M1HPAP headphone amplifier is equipped with dual 1/4"  (6.35mm) headphone jacks on its front-panel.

USB Port: The Musical Fidelity M1HPAP headphone amplifier features a rear-panel USB (type-B) port for the connection of your Windows PC or Mac computer, so you can listen to your stored compressed music files with high-quality sound from a set of headphones. The M1HPAP supports audio files such as CD, MP3, WMA, WAV, AAC, and FLAC. The M1HPAP's USB (type-B) port supports Windows 98, ME, 2000, XP, Vista, and 7; as well as MAC OS X.

Dual Analog Inputs: The Musical Fidelity M1HPAP headphone amplifier is equipped with two rear-panel, gold-plated, stereo RCA input for connecting two external audio sources. You can connect your receiver's Tape Output to the M1HPAP's stereo RCA input, or connect your CD player or other audio source directly to the headphone amplifier's line-level inputs.

Analog Output: If you connect the M1HPAP to the Tape Output of your receiver and the Tape Output is still required for a tape recorder or CD burner, then the M1HPAP's stereo RCA output can replicate the original Tape Output.

Preamp Output: The headphone amplifier's stereo preamp output jacks let you use the M1HPAP as a preamplifier and connect it to a separate power amplifier. When used as a preamplifier, the M1HPAP does not mute any connected speakers when headphones are plugged in.

Detachable AC Power cord: The M1HPAP is supplied with a detachable 7' IEC power cable.
