Accuphase C-2300
For more than half a century, Accuphase has continued its relentless pursuit of creating the ideal volume control circuitry. The C-2300 preamplifier utilizes Balanced AAVA – the successor of the AAVA system – to control volume without sacrificing vibrancy in the source sound. A newly added 4-band tone control enables fine adjustments to sound tone. Experience the sonic depth from the combined sound quality and superior features the C-2300 provides.
As with all the other integrated amplifiers, and some pre-amps, this can accept the plug-in DAC and Phono stage modules.
Accuphase C-2300 specifications:
- Balanced AAVA volume control

- Ample inputs: 5 Line and 2 Balanced
- Independent power supplies and unit amplifiers for left and right
- Phase setting memory for each input
- Highly reliable logic-controlled signal switching relays
- High-quality headphone amplifier
- Additional option boards support digital signals and analog records
Balanced volume control, Balanced AAVA
Conventional preamplifiers use variable resistors to adjust volume, which causes contacts to deteriorate and creates grit while increasing noise at normal volume levels. AAVA, however, produces multiple, widely varying signals from the input signal and controls volume by changing the combination of those signals. This achieves minimum noise at all volume levels without any grit. The C-2300 incorporates “Balanced AAVA” consisting of balanced “AAVA” circuits, which further reduces the noise level by approximately 10% over the C-2450.
Quiet and smooth volume sensor design
AAVA uses a volume sensor design to detect the position of the volume knob and changes the combination of signals to adjust volume. Machined from an aluminum block in an ultra-precise extrusion process, the C-2300 uses a volume sensor design developed in-house with hefty, rigid materials to achieve an utterly smooth and solid operation feel when rotating the knob for extremely accurate position detection. Operational sounds are subdued even when using the Remote Commander, resulting in quiet and gratifying volume adjustment.
