Metrum Onyx versus Metrum Pavane

Interesting thread as I also was wondering about this given the large price difference between the two.  I guess the implementation of the output stage, etc. is good or similar enough in the Onyx that the extra expensive DAC chips don't make all that big of a difference versus the added cost?  Whatever, this was interesting info. 

Given the apparently relative small gains to be had by spending $$$ on the Pavane, it would seem trying a DAC from another make might make more sense. SW1X is another R2R NOS DAC that seems to be really pleasing their owners, and they offer an in-home trial period (and an upgrade path, I believe). I’d be inclined to try that before considering the Pavane since I think SW1X may be less expensive and will likely produce more absolute differences in sound vs. the Onyx than the Pavane. Whether good or bad, who knows? But that’s why the trial period is so key. FWIW.

@justjames72 …. I've had great success using a Gustard U16 to convert from my laptops USB output to the AES/EBU input on my Onyx. Before that, I used a Matrix X-SPDIF2 powered by an Uptone LPS1.2, and that worked great too, but I think the U16 itself is better. I recommissioned the LPS1.2 to my ethernet switch.

So, are you going to take one for the team and audition SW1X against the Onyx? ;)  Would love to hear about that comparison!

I think they use tubes, which I think helps with the sense of utter dimensionality that owners seem to rave about.  No idea if better or worse than Metrum (that's always a personal decision anyway), but I think the use of tubes will make them sound different.  And I emphasize "different," not better or worse.  Again, they have a trial period and if you have the means it would seem like a REALLY good comparison.  Personally, these two are in the top two in my sites so I'd love to hear a comparison.  Someone did a comparison between an Octave and an SW1X DAC and preferred the latter, but I pretty much reject that as I don't think the Octave is near the performance of the Onyx nor an appropriate comparison, so the beat goes on. 

@1markr -- I'd absolutely love to do the comparo, but my amp is currently dead as would be my marriage if I tried to both repair my amp and buy another DAC at the same time.  Very much hoping someone else can do it though. 

The onyx is the best value for money. As said by the developper Cees Ruytenberg himself. But that said the Pavane delivers a bit more relaxing, punch en extra deep bass. It has a bigger powersupply. The only way to notice iff its worth the investment is to compare them both.
