Item: Corda Classic Headphone Amp Location: Goldcoast Price: $ 400 Item Condition: used / exellent Reason for selling: using all in one amp/dac Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: A few tiny marks (edge), not easy to see, no original box. Normal retail price new is $800. A very good sounding amp with two crossfeed stages and two gain settings. Tried a number of headphones with this amp ( HD800, SIG Pro, Alessandro MS Pro, HD600 & 650, T1, DT880 ). Every headphone sounded good with this amp esp. the Beyer T1. The DT880 was lacking a bit bass. Tech Data copied from Meyer: 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 also uses the concept of active balanced headphone ground. Within this concept each headphone connection wire carries an additional signal such that the sum of the potentials of the wires equals zero. This strongly minimizes the energies stored and released in the electrical fields inside the headphone cable when an audio-signal is applied. The influence of the wire on the sound is thus reduced. Moreover, with active ground pollution of the internal signal ground by strong driving currents is eliminated and the power-supply-rejection-ratio at the output stages is strongly improved. Thus the best conditions are given for a clean and undistorted sound. Active balanced headphone ground offers most of the advantages of a true balanced headphone setup without the need of balanced connections. It can be used with any conventional dynamic or magneplanar headphone. The volume control is technically very sophisticated. The position of the potentiometer is measured with the use of an AD-converter. The output of this converter is then used to switch a bank of relais to set the proper volume level. There are a total of 64 levels which allows for very small stepsizes and a very analog feeling. The advantages of this concept are strongly reduced channel-imbalances and a much cleaner and more detailed sound. The use of a conventional stereo-potentiometer does add its own sonic signature which is now prevented. The amplification section is build around AD797 opamps biased into class-A. For the output stages BUF634 buffer amplifiers are used. These integrated circuits are very fast and thus allows the output signals to follow the input signals very closely. The amp is DC-coupled and any capacitors found in the signal path are of the highest quality polypropylen and polystyrol. A very extensive powersupply, a large number of power-regulators, and a total filter capacity of 80.000 microF (!!) assure the best working conditions for any part of the circuitry. 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). To compensate for the psycho-acoustic bass-loss a separate switch allows to slightly increase lower-frequencies. Technically the CLASSIC is an extremely advanced headphone amplifier and offers excellent value-for-money! Pictures:

Item: Audio Technica ATH-AD900X Location: Goldcoast Price: $160 Item Condition: as new Reason for selling: Bought for my DAP but prefer a closed headphone. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Bought this headphone end of Nov 18 from AdA. Good sounding phone in this price class. Very seldom used. Relative wide & open sound stage. Low impedance 38 ohms. Open headphone. 100db/mW sensitivity. Easy to drive Comes with original box & adapter. Have dealer invoice. Pictures:

Regarding always on......I can't imagine its a good idea. Better ask the Chord company. I compared the Mojo with Dragonfly red. Its better in my opinion. And the Dragon Red is already better than the Black. The optical input works very good with a cd transport. Didnt try SPDIF yet.

I use it as a dac into a Meier Corda Classic headphone amp. I also used it as a dac for a Naim 5si integrated amp. Very good results. I copied some info regarding the line level output. The fixed value is a bit high hence I use only the highest dark blue color which is somewhere around 2mV I think ( not exactly sure ). I copied some info: Q. How do I set line-level output? Any volume level can be used for a line-level output. The Mojo will also remember the previously set volume when powering on. However, you can hold down both volume buttons when powering on to set the volume to a standard output level for typical line-out use. Q. Is there anyway to bypass the amp on the Mojo but still utilize the DAC? Will the line out function accomplish a bypass? No. For clarity, setting line level output does not bypass the analogue section as it's basically just the analogue output stage of the powerful DAC output. There is no seperate amp 'section' like in traditional setups. Mojo's headphone output is much more simple than what people are used to in a DAC/amp and is basically the same as Hugo with some minor hardware changes to accommodate the diminutive size. I think of it as always line level from the DAC with output power control. To sum up you don't activate or deactivate the analogue section. You simply set the voltage level to 3V when activating the line level.
