Chord 64 Dac. Near mint! [Expired]


no longer for sale

I am listing an almost mint Chord 64 in silver recently taken on trade. You honestly need a magnifying glass to find the tiniest mark in its chassis. Very, very clean unit. Unfortunately this unit lost its original box and packing years ago. I will be able to easily pack and ship quite well and safely. This unit works perfectly.

The DAC64 looks as if carved from a solid chunk of aluminum, the only visible highlights being a recess for the gold-plated logo and a convex glass window, though which the circuit board can be seen, illuminated by LEDs of various colors. In fact, these internal LEDs provide feedback to the user: When you turn the DAC64 on, blue LEDs light up. When the DAC64 locks to a data source, red LEDs add a purple hue. When either of the RAM buffers is selected, yellow LEDs illuminate.

The rear panel features three digital inputs—TosLink optical, S/PDIF electrical via a BNC jack, and AES/EBU on the usual XLR—selected by a three-position toggle switch. Although the specification states the DAC64 will accept 192kHz-sampled data, the necessary second AES/EBU jack doesn't exist. A second toggle selects between no RAM buffer and either of the two RAM settings. Both single-ended (RCA) and balanced (XLR) outputs are provided.

64-bit processing
In its announcement of the DAC64, Chord fired a salvo in the numbers wars by talking about a "64-bit" DAC. This sounds like overkill, considering CD's and DVD's respective 14- and 16-bit limits. And, of course, 64-bit performance implies a dynamic range that might well allow the Big Bang itself to be captured in full fidelity. But what is actually meant, as Chord's literature carefully explains, is that the digital reconstruction filter used in the DAC64 is realized using a 64-bit DSP core, and that the Pulse Array D/A chip uses seventh-order noise-shaping realized with 64-bit mathematical precision. Both mean that any mathematical error due to the filtering and noise-shaping calculations will be way below the analog noise floor, and therefore inconsequential.


Description: D/A processor with three digital inputs (XLR, AES/EBU; TosLink optical and BNC electrical, S/PDIF), RAM input buffer, and balanced and unbalanced analog outputs. Sample frequencies accepted: 32-192kHz. THD: <-98dB (1kHz, 24-bit data). S/N ratio: >110dB. Channel separation: >110dB at 1kHz, >100dB at 22.1kHz. Dynamic range: 120dB. Maximum output level: 6V RMS balanced, 3V RMS unbalanced. Output impedance: 75 ohms (short-circuit protected).
Dimensions: 13.3" (338mm) W by 2.4" (60mm) H by 5.7" (145mm) D. Weight: 15.4 lbs (7kg).
