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 powerful.
Reviews and Discussions :
- OPA209 op-amps biased into class-A.
- Sturdy anodized Alumunium Enclosure
- A total of 4 BURR-BROWN BUF634 buffer amplifiers at the left, the right, and the ground output channel.
- 1 pair of analog RCA-inputs (gold-plated)
- 1 stereo 3.5 mm input (silver-plated)
- Active balanced headphone Ground.
- Signal paths and its components at the bottom side of the PCB for maximal shielding.
- Low impedance electrolytic Buffer Capacitors (Nichicon). Total Buffer capacity 39.000 uF.
- Bypass capacitors in the power supply.
- Crossfeed filter switch which helps to strongly reduce listening fatigue.
Stereo / Crossfeed OFF
- Polystyrol and Polypropylen Capacitors in the signal path.
- Metalfilm Resistors in the signal path.
- Sophisticated Volume Control
The position of the potentiometer is measured with the use of an AD-converter.
The output of this converter is then used to set the proper volume level with a number of electronic switches. There are a total of 32 levels which allows for sufficient 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.
