Ok, maybe I was generalizing a bit Sometimes it's marketing, and sometimes there's something else going on. Some designers just push the 0.001% distortion for marketing reasons, but others get there for the right reasons. If you get there by designing amps with huge open loop gains, so that you can apply a ton of feedback, you're designing for marketing reasons. If you work hard at designing a circuit that has very low open loop distortion, and apply a small amount of feedback for stability, then you're designing for sonic reasons. And I agree that the second amp design will sound better. My point is that the numbers alone give you an incomplete picture, and are often misleading. -- DCtoDaylight Audiophile wish list: Zero Distortion, Infinite Signal to Noise Ratio, and a Bandwidth from DC to Daylight DCtoDaylight's Profile: http://forums.slimdevices.com/member.php?userid=7284 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Actually, nobody buys them, but that is not causal. Neumann has a bunch of "digital" microphones, based on the TLM 103 series, and the KM18* series. They make zero sense.

Early CDs (and digital mastering gear) had wicked low pass filters to eliminate anything over 22kHz. They screwed up too many things to list. With a 44.1kHz sample rate, there is nothing above 22.05 kHz. Period. No wonder ABX tests failed. Too many folks confuse this. Recording at 88.2 kHz means you don't need filters until 40kHz, and since there is nothing there, the filters can be nice first or second order networks. I've never hear any serious reasons to justify quad rate sampling. Bob Katz, a very serious mastering engineer, says that 18 bit samples at 55kHz would actually be enough, but with the way computers work, the next logical step is 24 bits @ 88.2 -- Pat Farrell http://www.pfarrell.com/ ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Good luck finding something with a dynamic range of greater that 144 dB. Typcially dither is not applied to 24-bit files, as the quantizing distortion on such a file is buried far beneath the noise floor. The main useful difference between 48 KHz and 96 KHz is that 96 KHz can use a reconstruction filter with a much gentler slope, which would typically have superior sonic characteristics.

I tested a few down to 16/44.1 and that did bring a noticable loss. -- lapis molari lapis molari's Profile: http://forums.slimdevices.com/member.php?userid=14462 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Not all 24/96 flac's are created equal
I would second the suggestion to create SB3-friendly 24/48 FLAC files from the 24/96 WAVs. Naturally, you would also keep the 24/96 files for when you get a Transporter (or SB4!). dbPowerAMP is what I use to convert the WAVs. When encoding to FLAC I would use the lowest compression setting, so the SB3's CPU has less work to do in decoding. -- Pale Blue Ego Pale Blue Ego's Profile: http://forums.slimdevices.com/member.php?userid=110 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Not all 24/96 flac's are created equal
As a matter of fact I used the FLAC Frontend yesterday to encode the 24/192/2.0 from the Classic HDAD of Alan Parsons' "Eye in the Sky". It can't do the ReplayGain calculation above 48 KHz, so that option must be unchecked, but it encoded fine.

Re: [SlimDevices: Audiophiles] Not all 24/96 flac's are created equal

They might think it's useful, but it is untrue except for a very bizarre definition of "just fine". Then they will repeat this incorrect information whenever the subject arises, and they will call tech support complaining about "problems" with 96KHz, they will think the product is defective, etc. That is why this "feature" was a mistake! What you are hearing is all of the content above 24KHz being aliased all the way across the audible band. The reason you hear noise with some files and not others is because some files may have nothing above 24KHz.

Yep, within the parameter that the SB isn't fully capable of supporting this function, I want it to work as well as it can. The SB's hardware limitations are not confusing at all, I'm confused why high-res flac's show different problems. My reason for posting, is that I found a solution to Elvis' stutter (see previous post) and I wonder if anyone else has found small solutions to make playback better. I also hope that other people will find it useful to read that certain 24/96 flacs play just fine on my SB. If it's useful for anyone that I do any specific tests or provide more details of my setup, just ask. Mr Adams, please don't remove this function.

BTW it might be worth investigating on-the-fly decoding, decimation to 48, and re-encoding to FLAC on the server for 96KHz content (would require flac of course, plus something like sox). If someone could provide a patch to do that it would be a much better solution. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Not all 24/96 flac's are created equal
So you mean, aside from the fact that Squeezebox does not do 96KHz, why doesn't it do 96KHz? :) 1) the audio outputs will not run faster than 48KHz 2) the cpu is not fast enough to decode FLAC at 96KHz 3) we try to play anyway, and drop every other sample to make it seem like it's working. This WILL sound bad because it is not a proper decimation algorithm, and since there is not enough CPU to even decode at 96KHz, there is certainly not enough to decode 96Khz _and_ decimate to 48KHz. I regret that we made it pretend to play 96KHz. The rationale was that it would be better than playing nothing in the case where a Squeezebox is synched with a Transporter. Unfortunately, it has just resulted in ongoing (sigh) complaints that it doesn't "work right". I don't really want to remove this non-feature because I'm sure whoever asked for it is happy to have it, but if it continues to cause this level of customer confusion then it will have to go. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Not all 24/96 flac's are created equal
I've read many posts covering the 24/96-flac problems for the SB3, but I have not found any that address the different symptoms of these files. - Classic Records DAD (extracted from dvd-v), several discs: play without problem, - Linn Records, Brahms violin crt & dances: has a much higher noise floor than normal files, - HDTT, Stravinksy's Firebird suite: no problem, - Chesky, Jon Faddis' Remembrances: no problem, - Elvis Presley, 30 #1 Hits (extracted the 2ch layer): SB doesn't keep up with datastream (flac lvl8: audiostream starts stuttering after 15-20 seconds, lvl5: after 1 -1 1/2 min, lvl3: slowdown is hardly audible, lvl1: I don't hear any delays). The Linn and HDTT were purchased in flac, the others I converted with flac 1.2 lvl5. When burned to a dvd-audio, the Linn noisefloor is not present. Converting the Linn flacs to wav and back to (lower compression lvl) flac does not make a difference. Stuttering Elvis also plays fine in wav, but that loses the tags. Everything is played from a wired Linkstation Live through a wired SB3. I appreciate Sean Adams' point that the SB was never designed for 24/96, but that doesn't mean we shouldn't see if we can minimise the shortcomings for this. Has anyone done rigorous research as to the cause of these problems? Is there a best version of flac to use for this? Optimal compression lvl? Faster NAS? I know the other two options: convert all my 96kHz to 48 kHz, or buy a Transporter. I'm saving up for the TP, but that's all the more reason not to want to downsample the music. P.S. Mr Adams, my compliments to a superb product-bundle (SB and ss) and the droolalicious bigger cousin (TP). -- lapis molari lapis molari's Profile: http://forums.slimdevices.com/member.php?userid=14462 View this thread: http://forums.slimdevices.com/showthread.php?t=41144 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
