Seeking Advice on NOS DAC


Looking to purchase an NOS DAC, budget is $1500.
Currently available for sale are:

- Metrum Acoustics Hex digital converter  (used)
- Metrum Acoustics Amethyst DAC       (new)
- Acoustic Plan Digimaster Tube DAC     (used)
This is a German-built NOS, 24-bit R-2R resistor ladder network, PCM1704U-K converter with 4 tube EC 86 triode outputs.
- HOLO Audio Spring DAC – LEVEL 2    (new, but over my budget of $1500)

My primary listening is via the PS Audio PWT, while music files on my Mac are steadily increasing. I’m thinking NOS due to my large collection of Redbook CD's.

So, any experience or comments on which way to proceed is appreciated.

@lowrider57 AN dacs of that vintage don’t have USB inputs, mine doesn’t I use coax. You could of course get a usb/spdif converter. As far as questions I wouldn’t stress too much about caps my DAC is Circa 1995 and still going strong. It’s a pretty low stress environment in terms of the output stage. perhaps ask for some interior pics? I don’t think there’s much to worry about AN has fantastic interior build quality.
Stretch your budget just a little for a used Pavane. You can later upgrade if you feel the need.  The base model is much better than the Hex and their Level 3 (run through a very good preamp) beat their highly rated Adagio head-to-head, for my tastes, in my system - although the Adagio was very good and other listeners may have called it differently.
I bought a Dodson D 217 mk. II d with 218 software upgrade and used it happily for over a decade. However, one of my system goals has always been to achieve ultimate transparency without crossing over the line into harshness. So when the Hex came out I decide to give NOS a shot and pulled the trigger and I do have to admit, the filterless approach does come off as a bit more organic and the micro shadings/information are more cleanly and decipherably presented. Then the Pavane reared its ugly head and after much deliberation and gnashing of teeth, I decided to take the plunge. It is MARGINALLY better but the sweet spot for the money is most certainly the Hex in my book. And I paid $3800 for my Hex brand new so at $1500, I'd be all over the one you're currently eyeing up.

I listen to redbook CD 100%.

Best of luck to you, whatever your decision.


Many thanks to @mitch2 and @acresverde . The Pavane will probably be out of reach (even used).
In addition to multiple positive reviews, Darko really liked the Hex. And there are two currently for sale; I may stretch my budget to $1650 for the right DAC.

Thanks, @jond . I messaged the dealer with some questions. I asked if any service was performed and if the original electronics were intact (very high-quality components are used).
I'm wondering why this unit is so reasonably priced, so I asked for pics.

Can anybody recommend a USB/spdif converter? And wouldn't this signal need to be reclocked and the 5V power be isolated?
FWIW, when I sent my Pavane over to the Netherlands for the upgrade, I purchased an Ayre Acoustics QB-9 DSD because I wanted music and because I always wanted to try one.  It was a nice sounding DAC but IMO and based on my recollection, I would have taken the Hex if I were offered the choice of either.  With respect to full disclosure, I have never warmed up to Ayre's house sound and of the several Ayre pieces I have owned, all have been well-built and very clean and quiet sounding, but I ultimately replaced all of them with pieces I found to be more tonally dense and organic sounding. And the other side of that coin, I have owned 3 Metrum DACs.
Back to the Hex, with the highest respect to Eddie Albert, Eva Gabor and Arnold Ziffel, I find the difference between Hex and Pavane to be much greater than reported by acresverde, but that is my opinion of what I hear in my system.  The upgrade to Level 3 brings another level of clarity and spatial believability.
And finally, if I were in your shoes, I would be looking hard at the Onyx or, if I wanted to ditch my preamp and simplify my system, then the Jade.  Both use the new designed in-house Metrum Transient converter chips that are used in the upgraded Pavane and in the Adagio.
Good luck.
