Please provide any impressions of the Wadia 121 DAC also any comparisons to Wyred4Sound DAC, Anedio 2, Metrum Acoustic Octave DAC. I have been unable to find user impressions or reviews on the Wadia 121. What power supply? Power Supply filter? Output stage? but most important sound.
It doesn't have any direct comparisons to the DACs you named, or the Burson HA-160D (which is what I'd like to see compared), but the article directly brings up the Benchmark to say that, all-in-all, the Wadia bests it (though, and I'm sure it's a relief for current Benchmark owners, by a small margin).
Sadly, the article is a tad short on surgical analysis of the Wadia's sound, and completely skips evaluation of the headphone-out - even though the opening suggests the possibility of at least some mention.
Alas, from what I have been able to gather, the Wadia is certainly worth the cost of admission, even among its foremost competitors.
