Re: [SlimDevices: Audiophiles] HD Music Downloads from iTrax
I own a few of your DVD-As and has read from one of the magazines from an article you wrote about high definition audio that you were planning for online downloads. Being a Slim user this is really good news and I am not suprised that you are also one of us. I was excited about download offering from HDTT and have bought a few of their downloads. But HDTT focuses on historical recordings so AIX with their well recorded material would be even better. One question I have is that SB3's digital output maxes out at 48Khz/24 Bit Stereo. Will you be offering that in addition to 96/24 for the transporter?

[SlimDevices: Audiophiles] Potential benefits of converting to 24 bit
In a thread on the ripping forum recently, mswlogo has sussed out how to 'up-bit-depth' his flacs from 16 to 24 bits. Filesize is similar, as it just compresses out, so no downside. The file is padded out with zeroes, so there is no change Potential upsides he gives are reduced jitter and (if applicable) better DRC from higher bit depth of processing. The latter I don't care about, but the former is interesting. Comments? I would have thought that higher bit depth would change the data timing, but would it always improve it?

Re: [SlimDevices: Audiophiles] Potential benefits of converting to 24 bit
Jitter will be exactly the same. The SPDIF spec transmits 32 bits of data per sample anyway; up to 24 of these are available for the sample word (with the bottom bits explicitly set to zero if unused!), and the rest are overheads such as sync pulses, checksums and other stuff. Apart from possibly changing a flag bit or two in the general-purpose data area, there is ABSOLUTELY NO DIFFERENCE between transmitting 16 bit samples, and 24 bit samples where the bottom bits are all zero. Since there is no difference at all in the bit stream, there will be no difference in downstream processing either. If a DAC is capable of oversampling / filtering to 24-bit accuracy, it'll be doing that anyway even with a 16 bit input, probably without even knowing the difference. -- AndyC_772 AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=34892 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Potential benefits of converting to 24 bit
If your going to upsample as well doing it in larger word length is more accurate (some would say a better guessitmate). Upsampling doesn't make a lot of sense with Slimdevices because SB3 only does 48khz and Transporter doesn't do 88.2Khz. BUt my library is for other devices beside the Slimdevices. I don't know why but in this stereophile review of the transporter 16 vs 24 changed the jitter measurement. http://www.stereophile.com/mediaservers/207slim/index4.html Snippet: I tested the Transporter's rejection of word-clock jitter using the Miller Jitter Analyzer, which examines a narrowband, FFT-derived spectrum of the analog output of the device under test (DUT) for pairs of sidebands around a high-level tone at one quarter the sample rate, while the LSB is toggled on and off at 1/128 the sample rate. (Both signals are exact integer fractions of the sample rate, meaning that any spuriae that appear in the spectrum are due to the behavior of the DUT, not to quantizing distortion.) Fed 24-bit data via the WiFi network, the Transporter developed just 235 picoseconds peakpeak of jitter with no data-related components (not shown). Decreasing the word length to 16 bits gave the spectrum shown in fig.10. Here the jitter level has increased slightly, to 268ps pp; though there are data-related sidebands (red numeric markers) at the test signal's residual level. The primary jitter components lie at ±15.6Hz (purple 1) and ±1435Hz (purple 10), but this is still excellent performance. -- mswlogo mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=34892 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I must admit, I don't know for sure why the test results are different - but I suspect it's much more to do with flaws in the test itself than the behaviour of the Transporter. For example, the AK4396 DAC is a 128x oversampling delta-sigma device, so there will always be data-dependent noise at frequencies outside the audio band. More than likely there is an analogue filter between the DAC and the output socket to attenuate this noise. Now suppose that, in order to allow excellent flatness up t0 22kHz, this filter has a cutoff around 100kHz. The test equipment is now trying to pick out jitter in the order of 100ps (which is the period of a clock running at 10GHz) in a signal which has been filtered to remove everything above 100kHz. Is that a sensible thing to try and do with any degree of accuracy? Or is the measurement likely to be influenced by the audio signal? I strongly suspect the latter.

Ok, thanks Andy, I think we are closer to the same page now. I figured it wouldn't hurt to play with. I'm also not sure how my processor handles 16 vs 24 bit and may do some odd things to be backward compatible with different devices. So I figured it wouldn't hurt to play with. The first thing my processor does is shift the data down to make headroom for some processing and calibration. I don't know if it does that in 16bit on 16bit data or converts first. It is capabable of outputing 16bit data to older active speakers and that data is just lost. With newer active speakers I can't tell what it does because SPDIF data is encrypted. So far I hear no difference. But I need to try it on a wider range of music.

Re: [SlimDevices: Audiophiles] Potential benefits of converting to 24 bit
What I was getting at, is that your DAC, or your processor, or whatever else is connected over SPDIF, simply won't know whether it's getting 16 bit or 24 bit data. The SPDIF frame includes 24 bit positions for use with audio data, and a source that only has 16 bits available simply pads the missing bits with zeros. So, there cannot be any difference in how your processor handles the data. That's why you can't hear any difference. SPDIF (at least, the 2 channel uncompressed version we're using) isn't encrypted, BTW - just encoded to ensure plenty of edges for clock recovery. The AES/EBU spec is freely available and explains exactly how to decode it - you could do it with a storage scope and a pencil paper if you wanted. -- AndyC_772 AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=34892 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Yeah, this is just obviously true, at least if your goal is high fidelity (meaning accurate reproduction of recorded music). The differences between amps or sources operating normally is measurable but extremely small and usually inaudible, while the differences between speakers is (relatively) huge and easily audible. Furthermore some speakers perform much, much better than others, with good performance defined as, for example, a close to flat frequency/phase response.

I can only guess what you mean by unlikely or losing any data, but the only reason you would get more precision in the latter case is because the volume function you are describing happens to be designed to output 16-bits when given a 16-bit input. A volume function could just as easily generate 24 bits of output, or 137 bits for that matter, from a 16 bit input.

I re-read his postings and didn't feel that he was trying to be disingenuous at all. I have a laptop connected to my DAC as well as a SB2 (with modded PSU) and there isn't a big difference in sound between the two. I wouldn't expect one unless the jitter performance of the laptop was really bad compared to the SB2. For those of us with some iTunes store purchases, it's a damn fine alternative, and even on lossless tracks that I have ripped myself, it can sound better since SlimServer seems to induce volume clipping when compared to iTunes playback of the same tracks. -- CardinalFang CardinalFang's Profile: http://forums.slimdevices.com/member.php?userid=962 View this thread: http://forums.slimdevices.com/showthread.php?t=34592 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: System Balancing � - your thoughts please
Heard a Transporter at the Sound Vision show back in February... Awesome. Sounded better than a NAIM CD player on the same system. Problem is, I can't justify spending £1,200 on one. My current setup, sources first: Arcam DV-79 CD/DVD-Audio player Rega Planar 3 turntable, Ortofon 510 cart, Pro-Ject Phono Box II Technics RS-BX606 cassette deck Sony RCD-W100 CD recorder Sony MDS-JB980 minidisc deck Turtle Beach Audiotron Pinnacle ShowCenter Arcam AVR-250 AV receiver Mordaunt-Short Avant 908 front, 905C centre, 2x 903S surrounds BW ASW-1000 subwoofer Chord Cobra 3 interconnects between DVD and amp Cambridge Atlantic interconnects between everything else and amp Chord Rumour 4 speaker cable for front and centre Gale XL-105 for rears (buried into plaster) At present I use the Audiotron as a network media source as it fits nicely in the kit rack. Granted, a Transporter would be better for this (FLAC support anyone?) but as mentioned above I can't justify spending this kind of money. What I'd really love is a standard SB3 mounted in a hi-fi component size case with front panel buttons, but without the fancy DACs of the Transporter. Probably be happy without the dual displays as well... just a SB that will sit in the kit rack and look right - and be operable without the remote. I've had an SB3 hooked up to an offboard DAC (Arcam Black Box 50) and the results have been superb. -- Squirrel Squirrel's Profile: http://forums.slimdevices.com/member.php?userid=5785 View this thread: http://forums.slimdevices.com/showthread.php?t=34849 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Quality streaming music...
I am struggling a bit with the radio here. Sorry, I need some help and easy explanation. I really like the Shoutcast HAPPYDAY contemporary radio station, but I have lots of annoying dropouts, re-buffering, in the stream from time to time. I would love to get links to URL´s on similar, quality sound stations, these I can then glue into Tune in URL, or find at SqueezeNetwork, or do both I signed up at Radioio but the stations there dont suit my taste, sorry to say -- Anne Bryston B-100 SST, Squeezebox 3, Martin Logan Aeon I.

I agree that differences between source and amplifier components are less obvious than for speakers, but I have found (as Patrick put much more elegantly than me!) that source quality is highly linked with my overall enjoyment. Certainly many people share your views, but that just hasn't been my experience. I get tired of poor speakers as I start to notice their weak points, which jump out at me more and more on certain tracks. On the other hand I appreciate the qualities of speakers I like again and again - that sudden bass slam you can feel in your stomach, sparkling clarity on highs, warm mids, seamless crossovers, incredibly real soundstage. And yet I usually can't distinguish at all between sources, even over lots of time. I used to think that was just me, and it's still a possibility - but I've learned that just about everyone else also has great difficulty distinguishing digital sources and amps, at least when blind. Granted, those are short tests, and you can always find something to criticize in them - but no one has any difficulty at all telling speakers apart.

O, I tend to agree with you but once you have a highly resolving speakers the other components start to make a bigger difference. I do hear some differences between amps and digital sources in informal blind lstening (which might not satisfy your rigorous criteria for a blind test :-) ) I do think one may have to spend the most on speakers to get the best results. It seems amps and DACs get to SOTA at a much lower price point than speakers. I did blind test Transporter V SB and the TP was significantly better. I also blind tested the XLR V RCA outs of the TP into my balanced amp and the XLR was much better than the RCA. We did level matching and my preamp switched silently and seamlessly between RCA and XLR. That difference was so large that all 3 people listening prefered balanced every time. I only refer to this to make the point that once the speakers are optimized , upstream components can become more important.
