If your comments are based on actually listening to the unit in question, and are not just blind, glowing, praise with no point of comparison (either us knowing what your preferences are, or drawing a comparison to a known product), I don't think there's ever been an issue here. The people that run into trouble are the ones whose first posts are full of breathless superlatives for a product no one has asked about, is from a brand with an unknown rep (or a known one that hasn't been great), and that then double down on hyperbole when anyone asks a question. This is surprising, given that the dac1541 has about double the output power of the Holo Audio Cyan (this according to the manufacturer's own specs for both devices). It'd be interesting to measure them in this regard. I was personally surprised that the dac1541 seemed to run out of steam with my Abyss and LCD-4 given it's power specifications, so maybe something is up there. -- Now, I've NOT heard the Holo Audio Cyan (in either incarnation). I could likely get one as a demo, as Holo Audio USA is just "up the street," but I've not done so so far. This is primarily because, having heard a number of DACs that use discrete R2R implementations without some kind of compensation*, parallel R2R modules*, forward correction* or that are not employing a sign-magnitude implementation*, they've all proven to be rather less than impressive. There are major challenges with using simple switches and resistors, not just in terms of ensuring linearity and monotonicity in a single channel (let alone matching two channels). And I'm not sure if the Holo Audio Cyan falls into this camp of a simple discrete implementation or if Jeff (the designer) has other things going on that help sidestep the issue with simple discrete resistor designs (mostly because pretty much all that's said on the sites about it is that it does NOT have the linear compensation of it's big brother). This is not to say I think the Cyan will sound bad. I'm just wary - based on experiences with other units with outwardly similar architectures (and it's possible there's stuff going on that's not disclosed that makes a big difference). -- *Among well-known, high-performing, R2R DACs, with discrete converters, the Holo Audio Spring DAC employs "linear compensation", Metrum use multiple DAC modules with a segmented conversion architecture and feed-forward correction, totalDAC use overlapping DAC modules and Soekris use a sign-magnitude implementation.
