To me it sounds like the piano is missing some of it's impact because of resonances from the recordplayer-arm. The Denon 103 is a very low compliance cartridge, so resonance could be an issue. I've tried to mitigate this by using a high-mass arm. The resonance peaks at ~9Hz, which is considered 'ideal'. But this does not say anything about the magnitude of the resonance. I have no idea how low it is in my setup. Does anyone else hear any anomalies in the recordings that might be attributable to arm resonance? Mani. |

Mani, It's not the 9 Hz resonance but the ones at the audible frequencies like the page about the Funk Firm Fxr arm shows. If you see that, your heart skips a beat, but of course help is on it's way. Just buy their arm.  BTW. Funk Firm is the new name for the restarted Pink Triangle firm, known for it's very good=neutral sounding record players. |

>My understanding is that dithering has nothing to do with HDCD decoding, so shouldn't be an issue here. Yeah - but it has to do a lot with encoding... Or maybe not a lot as Peter suspects and as I will try hopefully try to test soon  |

I've finally found an old licensed copy of secret rabbit resampler I knew I had somewhere but never really needed before now Since discussion seems to indicate that SRC is more important than dither I made couple 90 secs samples from master 24/176 with secret rabbit (with 2 different dithers - just to be sure), sox ( http://sox.sourceforge.net/SoX/Resampling) and same pro-resampler used for v1 but this time set to max aka 'ideal' filter steepness. So, for those still not totally fatigued : http://www.filemail.com/dl.aspx?id=SWAJCATOPTNNITT Peter, can you put your head again in your horns and check if distortion ('quantization noise') in <0.5 sec is still there? (I honestly can't hear it: maybe because I'm on the road and putting my head into 10cm portable speakers does not quite work, lol If it is, then it can't be aliasing filter can it? (with 4 different algorithms?) On a separate note: Did I understand correctly that AP is performed in real-time? If so, doesn't that go against the principle of no processing during playback? (or did you compare to AP pre-processed files and found no impact?) |

Josef - Nothing is done in real time. But maybe I confused you with calling AI a "pre-pre" process. AP is a "pre" process. As how I call it, a pre-process happens all in memory, while a pre-pre is happening even before the sound engine starts (FLAC conversion would also be an example). So, a pre process happens in memory, but not during playback. Before it. When I can use the room again (family is watching some TV right now), I will look for quantization noise ! ... and hope it is not there this time ... |

In sequence of "least noise" :
1. Sox.
2. Mani's (but difficult to compare because of the longer lead in; could be equal so Sox just as well).
3. Rabbit Dither2
4. Rabbit Dither1
5. v1-Max
6. V2
7. DND (actually equal with V2).

Of the four new 16/44.1 files posted by Josef, my strong preference is for v1-Max. I don't think much of the two Rabbits or the Sox.

As an interesting aside (and a welcome 'Time Out' from 'Take Five'... ), Blue Coast Records are offering some free downloads here: http://www.bluecoastrecords.com/cas-2010-downloads. My understanding is that these were originally recorded in DSD on a Korg. They have been converted to PCM in two resolutions: 16/44.1 and a 24/96. It's quite interesting to compare these two versions. (But I have to say that I really don't like DSD. I wish they'd just have recorded in hires PCM in the first place.) Mani. |
