Acoustic Plan DigiMaster, DriveMaster and dedicated power supply - MINT! [Expired]


no longer for sale

Mint condition Acoustic Plan DigiMaster DAC, DriveMaster transport in special edition silver faces, and power supply.  Original 15amp power cable, dedicated IS2 umbilical between DriveMaster and DAC and connector cables to power supply.  Second owner, purchased directly from Pitch Perfect Audio.

The CD transport DriveMaster (retail price $4750) is equipped with the famous CDPro2, also used in studios, test equipment and continuous music reproduction units. Together with the special suspension of the drive module a highly accurate readout is ensured. The DriveMaster has two digital outputs, a SPDIF output with BNC connector and a non-standard I2S output. The I2S connection direct to the D/A converter DigiMaster allows a direct data transfer without converting and converting back of the SPDIF signal.  The DriveMaster includes a compact remote.

The DigiMaster DAC (retail price $4750) has both USB as well as the SPDIF inputs, both have 192kHz/24 bit receivers and they pass on the data stream to the 24-bit R2R PCM1704U-K converter. Neither upsampling nor oversampling is used and this keeps the data as pure as possible. The USB data transfer works in an asynchronous mode, whereby the clock is determined by the high precision clock generator in the DigiMaster.

The minimalist philosophy of the circuit design is continued in the analogue filter and in the analogue output stage. For that reason, only analogue filters are used to cut off the undesirable ultrasonic frequency range. Depending on the sampling rate, the filters are switched to the proper cut off frequency. The analogue filters consist of custom-made precision inductors and capacitors. A pure tube output stage amplifies the small analogue signals and provides a low output impedance to partnering electronics.

The software of both devices (DigiMaster and DriveMaster) is developed "in house" exclusively by Acoustic Plan.

Available as an upgrade, the external power supply (retail price $2000) with linear regulation of Acoustic Plan’s own production is also included. This power supply is able to supply two devices of the Master series.

Total retail price of set is $11,500; asking $5200 in perfect mint condition.  See reviews below.
