Even here ABX testing helps, because it can help you establish what descriptions are real and which are not with carefully chosen music. No, it can't. This is one of the points I've been trying to get across. ABX can't identify "real" differences — there's no such thing. Perception varies from pe...

Yes, but no-one would question that. People do question if you can hear the difference between cables, between 32KHz and 48KHz and between downsampled TrueHD and pure TrueHD. Don't they teach the scientific method at school any more? Hmm, I think the problem is that I have misjudged my example. I h...

I don't need an ABX to tell that there is a real, audible difference between 32 kHz and 48 kHz audio Yes you do. The whole point about ABX is not to prove differences where the differences are very small and you are not sure if you are hearing them, but to disprove differences when you think you ca...

I agree on all accounts. This sums up the discussion very well. OJG Finally got around to updating the article with the correct line levels.

The point of an ABX test is so you know that the difference you're hearing is real. I've browsed audiophile forums, and posters will swear that they hear a difference between FLAC and CD audio, that they really need $1000 speaker cables, that putting a little chip on top of their CD player improves...

Did I understand correctly that in the subjective evaluation, you compared the Xonar's analog signal to the HDMI/optical/coaxial while the source was the same and let the Yamaha do the digital to analogue conversion? It would've been nice if some note was made about the Dolby TrueHD etc. HDMI-audio...

12 dB is a fairly commonly used rule of thumb for average crest factor in music and speech (I dispute your 16 dB number). This crest factor varies a lot between different types of music. Classical and metal being on opposite sides of the spectrum. Agreed. I didn't mean to suggest otherwise, though ...

PS Go to a high end A/V store and get a benchmark for your eyes and ears. What do you suggest?

I looked at the full RMAA results and discovered an anomaly: the frequency-response curves extend past Nyquist! Any ideas about what's really happening here? No, sorry.

Even if I know the answer, why just why didn't you test bit-perfect S/PDIF playback? I didn't see any testing of Dolby Digital or Dolby ProLogic either!

I think there is a mistake in the review. It states that the Xonar is the only way to get protected high resolution audio formats over HDMI on a PC, but the Radeon 48x0 cards can do it as well. As such, no sound card is required at all and the 48x0 cards also do full hardware decoding of the video,...

Maybe you have confused nominal levels with maximum levels? The difference between these two levels is called the headroom. It allows for handling signals with a high crest factor (peak to rms ratio) such as music. The nominal consumer output level is -10dBV. Thus the CD-player format allows for 16...

Some thoughts... I've been running a 1TB GreenPower in my HTPC for over a year now. I've clocked ~60K cycles, at a rate of roughly one every 30 seconds (my power-on hours are about 2K). Maybe I'm not a typical power user, but, even though my cycles are higher than they could be, I'm still not going ...

WD has officially responded to this issue, acknowledging that the 8 second unload timer can conflict with certain software, causing these unduly high spin-up counts.

SPCR gets coverage on TekZilla
SPCR shows up in the press from time to time because, even after we've been existence for five years or more, the idea that computers should be quiet still provokes a "why didn't I think of that" moment in a lot of people.

Note, you're not shorting +5V to ground, you're loading +5VSB (separate from regular +5V) with a resistor. Shorting any line to ground will kill the PSU or at a minimum activate the over current protection. Most likely, your +5VSB line has a capacity between 2~3A, and you should only need a couple w...

I'd suspect the power supply. I've encountered a number of power supplies that produce the noise you describe at extremely low load ... which is why we started doing low-load testing in our reviews.

That's pretty poor surround support if true ... did Intel really build a Dolby Pro II encoder into their sound card?
