Both are in perfect working condition.
$400 shipped and paypaled.
I only ship to CONUS.
I have sold and bought some stuff here on headfi. Check out my feedback.
The DAC-2 is manufactured by The Parts Connection, a division of Sonic Frontiers. It employs the Crystal CS 8412 input receiver, a receiver that has been utilized in many highly-regarded DACs.
At the heart of the DAC-2 is a pair of Burr Brown PCM-1702 20 bit DACs (one per channel), a chip that has traditionally seen duty only in more expensive processors.
Although HDCD-encoded discs are still relatively rare, Sonic Frontiers has chosen to include the Pacific Microsonics PMD-100 HDCD decoder/filter, making it one of only a few DACs in this price range to make use of this chip. A clear indication that the engineers at Sonic Frontiers have their sonic priorities straight is that the DAC-2 performs the 6dB attenuation of non-HDCD encoded discs (required of all HDCD licensees) in the analog rather than the digital domain.
Attenuation in the digital domain would result in the loss of 1 bit of precision from each digital sample, while attenuation in the analog domain allows the DAC-2 to take full advantage of the 20 bit resolution of the Burr Brown DACs.
The DAC-2 improves upon the power supply of the DAC-1 with the addition of more filter capacitance and three more voltage regulation stages, for a total of eight.
Improvements have also been made to the analog output stage, which now contains the Analog Devices AD817 output buffer as well as high-quality Holco metal film resistors.
The DAC-2 is one of those rare products that has the ability to perform at a level far exceeding that which you would expect at its price point. In fact, in many areas, the DAC-2 was competitive with, and even exceeded, the performance of processors twice its price. The DAC-2's ability to convincingly render a three-dimensional soundstage… Whoever coined the phrase "it's all in the details" must have had the DAC-2 in mind, as the processor's retrieval of recorded detail was exemplary… One of the more impressive aspects of the DAC-2's performance was the way in which it surrounded instruments and instrumentalists with large amounts of "air", heightening the illusion that living, breathing entities were responsible for the music-making.
Audio Alchemy DTI Plus anti-jitter device
Audio Alchemy’s DTI Plus offers inputs optical sources and provides a single coaxial output. Crystal's evergreen CS8412 interface chip with its free running PLL (Phase Locked Loop) offering jitter rejection beyond its 20kHz bandwidth. AA then provides a second stage of dejittering with a discrete crystal-based PLL. This master oscillator is used to re-clock the CS8412's digital output to the DAC.
