HEADPHONE AMPLIFIERS
Sure, you don't need a headphone amplifier to listen to your headphones. Just plug them in the headphone socket of your CD-player or integrated amplifier and you will be able to enjoy your music. Unfortunately though the headphone outputs on most of these devices are merely low priority afterthoughts and are made using the cheapest components. They sound accordingly.
And even the sound quality of portable players, specifically designed to drive headphones, is far from optimal as driving capacities are strongly restricted by the low supply voltage of the batteries, built-in limiters, and by coupling capacitors at the headphone output that prevent offset voltages but also the low frequencies from reaching your headphones.
Therefore, if you like to hear your phones in their full glory then it's almost inevitable that you buy a decent headphone amplifier.

The CORDA amplifiers found in the list below are designed to provide a maximum of sound quality for as little as money as possible. The enclosures are very sturdy build. No gimmicks that would increase price but don't add anything to the sound. However, no money was saved on the electronic components. Inside only parts of the highest quality are found. CORDA amplifiers and DACs have a detailed, clean sound and high driving capacities and some also have a proprietary crossfeed filter that makes headphone listening more relaxed and natural. In my opinion they simply represent excellent value for the money and you will have a very hard job to find better sounding amplifiers for the same money, if any at all. Just send me a mail if you're interested.

Note: All prices include world-wide shipping. Unfortunately customers who live inside the EU (European Union) have to pay V(alue) A(dded) T(axes). Therefore their prices are higher then those for customers living outside the EU. Please understand.

CORDA
JAZZ
This amplifier may use a relatively simple enclosure but at the inside it offers many technological ingredients not found in any other headphone amplifier in this price-range.
The JAZZ uses the concept of active balanced headphone ground and has a discrete volume control. As a result there are no audible channel-imbalances and sound is clean, detailed, and powerfull.
This amp also has our proprietary crossfeed filter incorporated which helps to strongly reduce listening fatigue.

CLASSIC
outside EU: €295,- / USD 405,-
inside EU: €345,-
technical details
outside EU: €515,- / USD 700,-
inside EU: €595,-
Sure, from the outside the CLASSIC looks very modest and plain. However, technically and sonically this is the best and most advanced amplifier that we've ever build.
Of course this amplifier uses the concept of active balanced headphone ground and a digital volume control. The sound level is set by switching a bank of electro-mechanical relais.
The built-in crossfeed filter is a frequency-extended version of the natural crossfeed found in previous CORDA amplifiers and provides even better imaging. It also offers three intensity levels (Stereo, medium, high).

ROCK
This amp lives up to its name. Despite it's small size it delivers great and powerfull sound. The basic concept is relatively simple but very high quality parts are used, resulting in a detailed sound with fine pace and rhythm.

Because of its qualities this amp has been choosen member of the InnerFidelity's "Wall of Fame":
!! All prices include world-wide shipping !!
outside EU: €185,- / USD 255,-
inside EU: €220,-

The QUICKSTEP is simply one of the very best portable amplifiers on the market and uses the concept of balanced ground and a discrete volume control.
In addition it has an extensive RF-filter of the input-signal which makes it immune to RF-pollution caused by mobile headphones.
It also has heavy-duty 3.5 mm sockets which strongly reduces contact-problems and increases reliability.

QUICKSTEP
outside EU: €215,- / USD 295,-

outside EU: €295,- / USD 405,-
inside EU: €345,-
The PCSTEP is a portable amplifier that, in addition to its analog input, also has a built-in USB-DAC (16bit/48kHz). When connected to the USB-port of your PC it will strongly improve on the sound that is provided by a standard quality soundcard.
The amp has a discrete volume control (32 positions, two gain settings), resulting in a clean sound without any channel imbalances.

DACCORD
outside EU: €555,- / USD 775,-
inside EU: €645,-
The DACCORD does not have a fancy enclosure but in reality it is a state-of-the-art Digital-to-Analog converter with integrated crossfeed and volume controlled outputs.
Inside two top-of-the-line Wolfson D/A converter chips in dual-mono mode, a large battery of audiophile capacitors, ultra-fast opamps in class-A, high-precision oscillators (TCXO), and many other very high-quality components are found that are exemplary for this price-class.
Two coxial, one optical, as well as an USB-input (24bit/192kHz!) allow for easy connection of any digital source, including your computer. A variable output allows to directly drive a poweramplifier or a pair of active loudspeakers.
The built-in crossfeed filter is a frequency-extended version of the natural crossfeed found in previous CORDA amplifiers and provides even better imaging. It also offers three intensity levels (Stereo, medium, high).
