Acoustic Plan DigiMaster
In spite of the small size of the CD transport/DA converter combination the DigiMaster and DriveMaster meets the superior quality demanded by high-end audiophiles. The D/A converter DigiMaster has probably the most consequent high resolution digital audio processing related to simplicity of all converters on the market nowadays. The USB as well as the SPDIF inputs 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. To avoid ground loops between the PC and the DigiMaster, the USB receiver circuit is powered by the PC, whereas inductive couplers (iCoupler) provide the galvanic separation between the two units. 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. All devices of the Master series have an external high quality switching power supply as standard. They meet the latest energy saving directives and have a medical approval for low electromagnetic radiation. As an upgrade, a power supply with linear regulation of Acoustic Plan’s own production is available. This power supply is able to supply two devices of the Master series. The software of both devices (DigiMaster and DriveMaster) is developed "in house" exclusively by Acoustic Plan.
Acoustic Plan DriveMaster
In spite of the small size of the CD transport/DA converter combination the DigiMaster and DriveMaster meets the superior quality demanded by high-end audiophiles. The CD transport DriveMaster is equipped with the famous CDPro2 wich is also used in studio's, 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 to the D/A converter DigiMaster allows a direct data transfer without converting and converting back of the SPDIF signal. All devices of the Master series have an external high quality switching power supply as standard. They meet the latest energy saving directives and have a medical approval for low electromagnetic radiation. As an upgrade, a power supply with linear regulation of Acoustic Plan's own production is available. This power supply is able to supply two devices of the Master series.

Auralic Vega dac -Aries Streamer
VEGA, the next generation digital audio processor, is developed with the goal of 'seeking for non-compromised sound'. With plenty of I/O ports and powerful function, it will become the kernel component of your high-end stereo system. With Sanctuary Audio Processor as heart, AURALiC introduces several cutting-edge technology for VEGA: Megahertz upsampling algorithm up-samples all PCM music to 1.5MHz in 32bit; Femto Master Clock provides an ultimate clock precision with jitter only 82 femtoseconds(0.082 picosecond). Binding with other AURALiC's patented technologies such as 'ORFEO Class-A module' and discrete 'Purer-Power™ solution', VEGA will bring high resolution music playback experience to climax. VEGA supports all high resolution music formats including DXD(352.8KS/s, 384KS/s in 32bit) as well as DSD stream at 2.8224MHz and 5.6448MHz. Five digital inputs include AES/EBU, coaxial(set of two), toslink and USB. The balanced and single-ended analog outputs can connect to power amplifier directly, adjusting volume in digital precision without dynamic loss. The Flexible Filter Mode embedded inside VEGA has six modes, each contains several digital filters optimized for corresponding sampling rate. These filters are solely developed by AURALiC to optimize the listening experience for different music and format. VEGA allows its user to customize according to different music formats, tuning sound best to personal preference. The ARIES serves as a “bridge” between music files on network storage or high quality online streaming services and the consumers’ DAC — enabling DACs for the first time to stream high-resolution music quickly and wirelessly in virtually any sampling rate, including DSD, Double-Rate DSD and DXD. The inputs of ARIES include Dual-Band high-speed WiFi, Gigabit Ethernet and USB 2.0 port. The outputs are USB audio host buffered by AURALiC’s patented ActiveUSB™ technology; low jitter digital audio outputs: AES/EBU, Coaxial and TOSLINK. The USB audio host can deliver PCM from 44.1 to 384 KHz at 16-, 24- and 32-bit resolutions as well as DSD, Double-Rate DSD for compatible USB DAC. The other digital outputs are limited to 192 KHz at 24-bit in maximum according to S/PDIF standard. ARIES is bundled with AURALiC’s Lightning DS App. The App has the capability to fully control ARIES to browse your music libraries on your network-attached storage (NAS), to stream high quality music content from service providers like Qobuz and WiMP, to control the playback and to select the hardware settings such as output channel and WiFi network, etc. The App also supports Songcast, a music distribution service that allows users to map computer’s sound to any Lightning-equipped system and to map sound between different Lightning systems in the house and streaming sound though Apple AirPlay.

Wavelength Brick USB Digital DAC
Very similar to the 'Cosecant' above, except that the output stage of the Brick is a single 12AU7A dual triode in reactor follower mode that has the great ability to deliver the goods. The Brick uses custom code developed by Wavelength Audio to support USB ASYNC mode. The Brick has a very low jitter central clock that runs the entire audio section. The output 16/44.1K of the TDA1543N2 (5% top selected) multibit dac and passive I/V is directly connected to the 12AU7A/ECC82 output tube which in turns drives the reactor follower output for excellent drive and sound
Wavelength Cosecant V2 USB Digital DAC
"The Cosecant is one of the coolest ideas I have in a long time. This allows your computer to be converted into a media central unit. That's right you can use the computer to play CD's in the CD drive. Or move songs to the hard drive and create play lists. Or you can stream music off the internet, play movies the list goes on. One of the reasons this works so well is because ounce the track is ripped (copied) to the hard drive error free it just sounds better than any transport available. The Cosecant does not use a USB DAC chip. It instead uses a non up/oversampling multibit dac with out the use of analog or digital filtering. The idea that what is on the disk is exactly what is going out without any math involved between disk and output." - J. Gordon Rankin, Wavelength Audio
Wavelength Proton USB Digital DAC
The Proton USB Digital DAC from Wavelength is for desktops, home audio, travel whatever! The idea is to make a dac that could run without a power supply and still sound wonderful. The idea is simple: we can use the USB power to provide for the necessities and then for the critical areas the LiION battery can supply the extra clean power for the dac and the headphone outputs. The Proton supports 24 bit data at 44.1, 48, 88.2 and 96k and is indicated on the rear by four leds. The volume control icon for the headphone output will appear on the computer desktop. Setting the volume slider on the computer will result hardware in the Proton to set the analog volume control for the outputs to the desired setting.
