Didn't know you liked 2 Live Crew Steve --

The issue is ameliorated by throwing money at it, (smoother DAC filtering/alternate methods) but you can't add information that isn't there in the first place. Yes, the 44.1Khz sampling rate was chosen to be 'good enough', but 'good enough' doesn't seem to cut the mustard, hence the drive to higher sampling rates. So I'm not talking about throwing money at the 'problem' per se, just trying to address the topic; why the same source will sound 'better' on Vinyl than Digital (as in Steve's experience with the swirling guitars). My $0.02 is that it has SOMETHING to do with low level detail loss due to quantization noise, a loss that $$$ won't recover, just (perhaps) filter more smoothly. Again, this is comparing Vinyl to CD, not saying that higher sampling rates (more $$) won't get better, just that low level detail at the CD sampling rate is different than on vinyl.

I agree with most of your comments re expediency of format, higher order issues, overall enjoyment v. time spent 'tweaking and adjusting' etc., but a low level signal on CD, the sample of the original music, IS stair stepped because there's a greatly diminished number of samples available in the amplitude domain with which to sample it. Sample 1Khz with a million amplitude steps and you'll get a fair approximation (sample). Sample 1Khz with 100 amplitude steps and you'll get a staircase sample. Now, play BOTH through the DAC and it's interpolation and the staircase will no longer be a building block of square waves (the interpolator takes that out) but it will still sound bad, it will still be a worse approximation of the original and it CAN't replace information that's been thrown away during quantization, it can only smooth out the steps between them. So the samples on disc at low levels ARE stepped; the anti-alias filter will do it's best to recover what the original analog waveform WAS, but it can't know what happened BETWEEN quanta, it can only interpolate between what's there with regards to the original topic, I think this has more than something to do with it

Yes, the output to the speakers from the player's DAC will be anti-aliased, but that's not the point. You said and that's what I did. If you have 2^16 discrete steps with which to chop up an analog signal, you can represent it with finer fidelity if you utilize all of the steps. If you only utilize 2^6 steps the analog signal will be notched.....the information is lost. Yes, it comes out of the speakers 'interpolated' by the anti-aliasing filter, but as you see in the two traces, one is severely an approximation of the other (there are errors in amplitude, time AND trending. Listen to the samples, you can HEAR how CD quantization loses fine detail (or 'grunges' it).

Here's tracks 93-96 of that test disc I talked about (careful, it's the same track at -60, -40, -20 and 'normal' levels, If you don't normalize the tracks or if you keep the volume cranked you'll hurt something). You can hear the grain in the tracks recorded at the low levels. That's what's being done to the low level detail in music on disc. http://thecarversite.com/yetanotherforum/userfiles/Qnoise.zip Here are screenshots of the same section of music, the normal track is black, the -60 dB track red. It's a superposition about 3 seconds in. NOt only is the low level track stairstepped horizontally (in time), but the lack of available bits for sampling volume changes means the low level track doesn't follow the amplitude with as much fidelity as the higher level track

IDK, I think it made sense. another interesting tidbit: http://www.cv.nrao.edu/~rfisher/SamplerErr/harmonics.html

Just click on the one you don't want, and in the pop-up info panel bottom right there's a delete button

Some say burning speed has something to do with it as well

or maybe headphones d:)b

Rabbit posted a link to SVS giving demo movies for deep bass. What songs do you like to listen to for deep bass. This can either be the sinewave sweep type of rumbly bass that Sould Coughing is known for, or deep yet tightly cohesive bass. The track with the deepest, yet still cohesive, bass I've found to date is 'World Machine' by Level 42

Dubbing is better in Black

Balok's still there, you both put pins in the same place, so you have to zoom WAY in to see them

I don't see either of yours anymore, did you delete them Both?

What's up with the map is, anybody can put a pin in the map anywhere and give it any name, so, if there are two pins for the same member, either he put two pins in there or someone else did.........

Wow.....looks very nice! that would make a great front end for a media center

When the page first loads there's a dialog box for you to add your pin. If you miss it, there's a spot in the upper right to do the same

so far mr X and Steve are up in Carver country, and I'm the only bonehead stuck in the middle of the continent.
