For Sale:
Audio-GD DAC 8 (like Reference 1)

Will Ship To: Anywhere

Ready to sell, no more second-thoughts.


The DAC 8 is a different version of Reference 1(DAC 8's interior looks almost exactly the same as the slightly newer Reference 1) and Reference 1 is the previous version to Reference 7 which is similar to Master 7. This unit was from 2009.


DAC 8 use the legendary PMD-100 by Pacific Microsonics (before acquisition by Microsoft) digital filter The unit use 8 PCM-1704UK DACs like newer models. It has the warmth of vinyl but clarity of digital.


This unit is in excellent condition, less than 100 hours in total, no more than 2 hour per listen, the unit gets hot because of class A output, good for winter listening. It's made out of aluminum and easily scratched, the physical craftsmanship is not nice as newest Audio-GD products, but this is unit very sturdy, cheaper and operates like new! I can take more pictures of different angles by request.


DAC8 + Blue Jean's RCA Interconnect, thick power cord, Canare BNC cable = $850 + shipping.


PCB is not missing any resistors, it was designed that



3 transformer physically isolated to eliminate EMI/RF

interference. Class A circuitry gets hot, it seems to

be a true Class A by the heat dissipation. I recommend

to turn off immediately when you're not listening to

music for reducing electricity cost.



The paint is fragile, but the metal is very strong and heavy.

Interested, but please provide eBay feedback or some other form of feedback? I don't want to get screwed over. :(

Is this still for sale? 

If so, I might consider taking it after moving to new place in August...

I still have it.


Pure Class A, only possible noticed distortion is 2nd harmonic order (pleasing tube-like, but less of it because solid state have less distortion in general).

No negative feedback (no inter-modulation distortion).

Clean power supply.

Heavy aluminum case for elimination of Eddy Current/Foucault Currents.

8 DAC chips to improve linearity with a simpler circuit.

Krell cast type configuration without cast cable requirement.

Truly balanced (Dan lavry from lavry engineering speculates based on measurements, it reduces even order harmonic distortion by 6 db when the system is fully balanced. The advantage of not picking up electrical interference is the second benefit).

S/N Ratio is >113db


Using software(e.i audacity, foobar with add-ons) for sample-rate conversion with 8 true 24 bit dac. (ESS 32 bit dacs are not real 32 bit dacs, more like 8-16 bit with processing to increase resolution). The data will still pass pacific microsonic's PMD-100, in case the software wasn't good enough.




Condition: Electronically, it's excellent. Physically, there are scratches on the paint/case.
