Re: [SlimDevices: Audiophiles] Can anyone recommend a Cambridge Audio DacMagic...
Cable-wise, you'll need either an optical cable or a coaxial cable, doesn't really matter which. I own the now discontinued DACMagic: whether you buy the DACMagic+ or the DACMagic100 will depend entirely on whether you want a headphone amp. Even if you do, there are cheaper and better options than the headphone amp in the Plus.

Re: [SlimDevices: Audiophiles] Blind listening - TT3.0, HWmods and Teddy Pardo PSU
Mnyb wrote: PSU could actually influence other parts of your hifi it is not necesarily the squeezebox that gets improved I've heard this a lot: I'm really not that convinced. For example, I have an O2 headphone amp: it's prettymuch a cheapskate objectivist's wire with gain for headphones. The power supply is simple and elegant, mainly consisting of smoothing caps and a couple of generic regulators. You can conduct an interesting test involving pulling the power cord out of the back, with the amp on and headphones plugged in. It'll immediately switch to an internal pair of batteries, causing a significant voltage fluctuation on both rails (12V to below 9V). No noise is produced in the headphones. Beyond the anecdote, the measurements reveal that the equipment doesn't really give too much of a crap about the power it's given. The power supply does a pretty good job, and the exemplary PSRR of a handful of cheap opamps does the rest. I really can't see this idea of mains contamination ever manifesting itself as something that might conceivably ever be audible: likely not even measurable in many cases, especially with the trend in hi-fi to overengineer the power supply for marketing kudos...

NoRoDa wrote: Don't know how the jitter relates to the PSU? Yup, of course, both locked on max volume. The issue isn't so much that, rather that such levels of jitter are extremely low: far, far below even the most conservative of reported audibility thresholds. When the one with the better power supply is clearly better under blind conditions and it's a digital connection, it seems a tad strange, to say the least.

Make no mistake: I'm not singling it out as flawed, just saying that it was probably also flawed. I'm very much on the worthless claims are worthless bandwagon.

The perfect blind test will never exist, but that shouldn't keep us from drawing conclusions regarding the cumulative weight of the somewhat less-that-perfect tests that have been performed over the years. The conclusion I've drawn from everything I've seen over the years is solid proof that we are human. Under sighted conditions (i.e., with knowledge of the make/model we're listening to at the moment), our comments are dramatic and full of hyperbole. As the knowledge-of-conditions slider moves slowly toward blindness, the differences reported get smaller, less certain and sometimes even disappear. Anyone who doesn't admit the obvious - that we are easily susceptible to subjective factors - is whistling past the graveyard. Agreed, but I still don't see why more emphasis wasn't placed on discussion of the test conditions from the get-go, to establish whether it could be classed as meaningful and/or to attempt to reproduce it.

Re: [SlimDevices: Audiophiles] Blind listening - TT3.0, HWmods and Teddy Pardo PSU
Did anyone ever verify that this blind test was conducted with any real degree of vigour? Call me a cynic, but I'm inclined to blame differences on things like failing to volume match within +/-0.1db and failures in test protocol rather than, erm, magic...

Re: [SlimDevices: Audiophiles] Triode's USB 24/192 plug in - sound quality impressions
The jitter thresholds being quoted here are a little too high. The 1998 study from Benjamin and Gannon established that when the program material was specially chosen jitter as low as 30ns could be distinguished under ideal conditions with specially chosen musical content and jitter of a variety most likely to be audible. That said, a more recent 2005 study which used random jitter found the threshold to lie at several hundred ns... Either way, this is vastly more jitter than produced by even semi-competent products.
