The Master Reference Ultra-Clock provides jitter performance 50x better than other clocks. Specifications of 2 picoseconds RMS and frequency accuracy of 0.0001% insure maximum dynamic range. The Master Reference Ultra-Clock circuit is preceded by a new aggressive 2Hz jitter filter, insuring that any incoming jitter on the data inputs can not compromise the final analog output signal quality. The DAC2.5 has been optimized to provide the highest level of performance for all of these critical functions. It can provide digital preamplifier as well as D/A conversion and bridge from traditional CD or DVD player sources and from the isolated USB input for computer music playback sources. All digital input sources benefit from the new 2Hz digital PLL stage that rolls off incoming jitter by more than 10X at 10Hz frequencies and greater than 10,000X by 100 Hz. Any incoming jitter at frequencies above 10Hz is reduced to levels that have no effect on measured or sonic performance. The combination of the internal LNS1 stage and the new jitter filtration provide a well isolated environment for the DAC2.5 Digital to Analog stage. The final conversion to analog is no longer subject to external noise and interference sources and the resulting purity and dynamic quality is highly musical and compelling. The High Dynamic Range analog input section provides 110dB of dynamic range for any of your analog sources-it can be connected to a PHONO3 preamplifier for a complete system including a turntable source. Or it can be configured as a Home Theater Bypass to integrate into a complete high performance system with the best performance for your 2-channel sources. The dedicated headphone DAC/Amplifier stage is designed to drive any headphone with remarkable fidelity. This dedicated stage insures no compromise to either the main analog outputs or the headphone output. The main analog outputs are muted digitally when a headphone is plugged into the front panel jack. There is no additional switching of any analog signals or routing of analog lines. The headphone circuitry is all DC coupled, avoiding any sonic compromise due to coupling capacitors. The PCM1796 dual-differential multi-bit delta-sigma DAC circuit achieves remarkable analog performance. The 4VRMS true balanced XLR outputs provide 122dB of dynamic range. The noise floor of this DAC/processor is so low and so clean that the DAC2.5 is optimally uséd as a complete DAC/Preamplifier with a digital level control. Because of dither applied to the 24bit word there is no loss of effective resolution. The application of optimized dither insures that the analog output noise floor maintains a clean sound, devoid of any tones or artifacts. The DAC2.5 can provide an optimum solution with the addition of a Bel Canto e.One amplifier, eliminating the need for an analog preamplifier Brand Background: Bel Canto Audio Designs is based in Minneapolis, MN and manufactures in the USA.

(6.5 kg) Testing Process: We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect resistors and other passive components for signs of overheating. After the visual inspection we connect the DAC's RCA outputs to our Sencore PA81 Power Analyzer which simulates a real world input impedance and allows us to monitor the output on an oscilloscope. We are equipped to test optical, coaxial, and USB inputs at Redbook CD Quality. We start with a test signal to verify signal lock and proper output on both channels. If the DAC has balanced outputs these are also tested at this time. If the DAC has multiple Optical and Coaxial inputs they are all checked for proper lock. USB inputs are tested with a MacBook Pro. After proper function is verified, we setup the DAC for a listening test to evaluate general audio reproduction quality and monitor for clicks, pops, or any other audible signs of issues related to dropped signal lock or failing audio output stages. We often connect the DAC under evaluation to our long term test rig for a long test stint to verify stability under real world operating conditions. ---------- SkyFi Audio - Curators of Vintage Audio Gear SkyFi Audio is a small startup business specializing in the purchase, reconditioning, and reselling of high end audio equipment.
