The all new ARIOSO is our latest offering in the integrated DAC / headphones amplifier category. We took our time in order to create something unique which makes us and you the customer happy. Meticulous design and redesign procedures were necessary before this outstanding DAC ultimately is now ready for shipment.

 

Although the ARIOSO has a well proven ancestor – the u:c:a, we had a lot of work to do. Nearly every subassembly has ultimately put to the test and modified when necessary. Some of these improvements are also present in the u:c:a mk2, while others are exclusively employed in the ARIOSO.

 

What came out is a DAC / headphones amplifier with outstanding characteristics differing from nearly everything the market offers regardless of price.

Product features:

Asynchronous USB transceiver - any form of jitter in the incoming datastream is compensated by a small buffer. The audio data is clocked out by a local high precision quartz master clock. With this operation mode, the DAC is the master, whereas the computer is the slave. Timing errors are effectively eliminated.

S/PDIF input: True 75 Ohms COAX plus TOSLINK inputs, digital quartz PLL synthesizer receiver with very low intrinsic jitter (< 50ps) 32 – 192kHz sample frequency range, 24 bit.

DAC: Upsampling to 192kHz, regardless of input rate. Master clock oscillator with 3ps periodic jitter. Passive I/U conversation with 0.1% precision resistors, zero feedback.

DSD support – DSD64 and DSD128 are supported natively. A direct signal path between the USB transceiver and the DAC chip modulator leaves out the digital interpolator stage common in PCM processing. The full jitter elimination of the incoming data stream due to the asynchronous mode USB transceiver is most important, because reclocking of the DSD signal is not applicable. Therefore, the USB transceiver plays an important part for the over all performance not only in PCM mode but in DSD mode too.

Linear, interference free power supply – The power supply used in the ARIOSO is a high current design with heavy filtering. An equivalent of 53.000uF is used for the analogue supply rails.

Easy and intuitive operation – no toying around, we already adjusted the circuit to optimal values for the filter algorithms and the filter bandwidth based on critical listening tests with headphones and speakers. The clear and non intrusive concept is also carried out under the hood. When looking inside, you won’t find a rat’s net of cables, instead you will discover a clean layout typical of true High End components.

… an analogue masterpiece: rediscover the sound of unspoilt discrete class A electronics.
