Re: [SlimDevices: Audiophiles] I want it bit-perfect
Thanks for the feedback and the link. Used to be an EE many years ago, and brain is getting befuddled these days, but surely any digital reduction of the sound will reduce quality. By definition, reducing the volume by reducing the digital values will reduce the size of the largest sample - thereby reducing the dynamic range. To use a trite example, reducing the volume by 50% digitally will turn the 16 bit sample into a 15 bit sample. Even if the processing is done in 24 bits, and the volume reduction is small, the dynamic range has been reduced and the quality of the output diminshed. Do you happen to know whether it is possible to disable the didgital volume control or whether the SB leaves the datastream alone if it set at full volume?

Re: [SlimDevices: Audiophiles] I want it bit-perfect
The point is that the original 16 bit is upscaled to 24 by adding 8 *redundant* bits, so if you lose them, you lose no information. To quote Robin from the link above, Here's an example using 4-bits / 8 bits: Original 4-bit audio: Processed as 8-bit audio: Half the volume : 0000 Half the volume : 0000 Half the volume : 0000 Half the volume : Notice, we've now reduced the volume significantly and have still not lost any resolution. and similarly if the original 4-bit was 1101, it'd be processed as 1101 and Half the volume : 01101000 Half the volume : 00110100 Half the volume : 00011010 Half the volume : 1101 The original information content, in the first example and 1101 in the second, is not lost at all by reducing volume. -- smc2911 http://www.last.fm/user/smc2911/ smc2911's Profile: http://forums.slimdevices.com/member.php?userid=4388 View this thread: http://forums.slimdevices.com/showthread.php?t=46229 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] I want it bit-perfect
Thank you for the reply and the link to the review. I will go and check the settings on the SB3, although I haven't changed any of them. I am not a believer in any of this voodoo 'I changed my mains cord and the sound is much better' stuff, and I understand that in principle the digital outputs should be the same, but.. When set up correctly (and it took me ages), with a decently recorded CD the martin logan's do an amazing dissapearing trick and it becomes impossible to locate the speakers, you just hear a broad soundstage. Its why I put up with their fiddly setup and their questionable looks. Use the SB3 and the speakers reappear. The best I can say is that it sounds a bit murky. I am a little concerned about the SB3 messing with the samples (the reason I put up with a 15 minute rip-time from EAC is to get all the original samples) so I will investigate this further. There are all sorts of posts on the fourm about the SPDIF drive circuitry in the SB3 introducing jitter in the digital feed. I will have a look at that as well.

Re: [SlimDevices: Audiophiles] Q: 'Alternative' CD formats..SACD, HDCD, XRCD
It's true that software development is not the same as mechanical engineering. :) The stringency of the process is generally somewhere between mechanical engineering and film producing. However, SW dev is different to both and the exact kind of process used depends on the application. For firmware used in nuclear weapons or flight control systems more strict processes are used. You will find that the project management, requirements management, design, testing and configuration management processes used are quite different in aerospace and military applications than in commercial development. BTW I come from a configuration management background. If you're a manufacturing engineer you'll know its equivalent as Product Data Management. In general, Pat is right to view software the way he does - it's played faster and looser 99% of the time than in mechanical engineering. Just like not all engineering is Engineering, not all software development is alike. But it makes no commercial sense to implement very strict processes when time-to-market, functionality and aesthetics are what counts to customers. It depends on the domain.

Thanks for the reply. I would agree that in the case of a 24 bit DAC, driven in the manner you describe, there would be no loss of resolution until the volume was reduced to 1/256th of the full volume. I am however using the DAC in my Krell. So the quesion is whether the SB3 outputs 24 bit samples out of the SPDIF connector, and whether the Krell would know what to do with them if it did.

Re: [SlimDevices: Audiophiles] I want it bit-perfect
The S/PDIF default is 20 bits and only equipment that supports 24 bits sees 24 bits. I'm fairly sure the SB3 puts out 24 bits...but I'm not sure about the Krell. BTW the issue with the digital volume control isn't bits (when working with 24 bits none of the 16 original bits are lost with normal volume ranges). The issue is with loss of SNR. Assuming the TP has 120db SNR you can afford to lose 24db before being 'restricted' to 96db. That is the dynamic range of 16 bit recordings. Don't know what the SNR of your Krell is...

Re: [SlimDevices: Audiophiles] I want it bit-perfect
A couple of points. First, you say you haven't changed any of the settings on slimserver. By default (unless this has changed, in which I'm sure someone will correct me) SS encodes WAVs as FLAC before sending them to the squeezebox/receiver. That means there cannot possibly be any sonic difference between the same file stored as WAV versus FLAC on your server. Since you were confident you heard a difference, your biases and expectations are having a major impact on the sound quality you perceive. I suggest you go back and do those comparisons again, blind (not knowing what is what). Have a friend (who promises not to give you any sort of hint, as that defeats the purpose) do the switches and record what your responses are. Second, the discussion digital volume reduction here is wrong (as I pointed out in the other thread, and as Sean has said as well). Nothing special happens at 1/256 volume. You should set the analog volume so that max digital volume is as loud as you will want; then using the SB volume will result only in a slight reduction of signal/noise. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=46229 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Yes, it has absolutely nothing to do with the amp drawing too much power. You never use it at maximum anyway. Electrical items like dimmers, refrigerators etc. might send out pulses on your electricity net, and some audio equipment is sensitive to that, and some are not. An off-line UPS will created separation from earth, but have other disadvantages, like sending even more noise out on the net. Besides they beeing expensive, you need to replace the batteries every 4-5 years maybe, and they are expensive also.

But, if you lower the volume to 99 the indicator goes out. -- Anne Squeezebox 3 Stereovox XV2 Bryston B100-DA SST Carlsson OA50.2 Sennheiser HD580 Precision Anne's Profile: http://forums.slimdevices.com/member.php?userid=10071 View this thread: http://forums.slimdevices.com/showthread.php?t=46229 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] please help: amp drawing so much power that i get interference from other equipment
Thanks all, I will take the recommendations. Pat: I still have three old amps in the house... one was my old amp in the living room... Never had the SqueezeBox on digital connection on that amp, as the DAC in the amp was... horrid :). The other amps (a small home theatre system in the bedroom, and a spare very old low range Onkyo currently not used, are not good alternatives for listening. I actually have not had many of those interruptions... just four or five in a whole weekend of listening... but, I will connect the SB to the analogue connection, and if that does not help, get some of those surge filters...

Re: [SlimDevices: Audiophiles] Transporter straight into an amp
You can experiment a little if your Krell has Pre Out/Main In. Then you can run the TP into Main In and then only use its poweramp section. It also depends on your speakers, I think that if you have Martin Logan the McIntosh would be a terrific match, along with the TP. You will find lots of threads here about running the TP straight into a poweramp, almost everybody report a gain in fidelity bypassing the preamp. You need a very very good preamp otherwise -- Anne Squeezebox 3 Stereovox XV2 Bryston B100-DA SST Carlsson OA50.2 Sennheiser HD580 Precision Anne's Profile: http://forums.slimdevices.com/member.php?userid=10071 View this thread: http://forums.slimdevices.com/showthread.php?t=46255 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Yup, any encoded signal (HDCD, DTS, etc) will only work with the volume @ 100 because that's the only time it'll be bit-identical to the original. -- radish radish's Profile: http://forums.slimdevices.com/member.php?userid=77 View this thread: http://forums.slimdevices.com/showthread.php?t=46229 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] I want it bit-perfect
Patrick Dixon;290982 Wrote: Hmm, I'm not quite sure which bit you think is 'wrong'. What's wrong is this whole bit perfect idea. It's true that if one wanted to take the attenuated digital stream and reconstruct the original data, that would be impossible when the volume is reduced by more than a factor of 256 (or even less if the gain factor is such that rounding is necessary). But that's NOT what one wants to do - not at all. You're sending the stream into a DAC, and the DAC converts it into an analogue voltage. The only thing that matters then is the S/N of the resulting analogue stream, and the S/N varies smoothly with the gain factor. There is no sudden change at 256, and there is also no change when there is rounding versus when there isn't. The reason is that the noise level of the DAC is well above the rounding errors. This is not just an opinion - it's a fact which can be proven mathematically and checked empirically (there was a plot of the S/N as a function of volume posted a while back). This isn't gong to be another of your 'can't hear -144dB' faux pas is it? Oh please. You were wrong about that, and you're simply not big enough to admit it. That's obvious to anyone reading that thread. You never had any response to the points I (and others) made - you just resorted to childish insults. It's possible that if you have replay gain tags in your FLAC files they would sound different to a WAV file (with no tags), converted to FLAC on the fly. That's a good point. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=46229 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Not impressed with the Transporter
I ordered a transporter and spent the better part of the weekend listening and comparing it to my SB3. For most of my music I could hear no real difference. With other, better recorded, music the transporter sounded a little more resolved and clear. I really like the additional hardware features but it lacks the musical impact I was expecting to hear. At this point I'm thinking of returning it. Anybody share any similar experience? The rest of my system consists of a McIntosh 6900 and a pair of BW 703. My music collection is all FLAC based. -- george_k george_k's Profile: http://forums.slimdevices.com/member.php?userid=2519 View this thread: http://forums.slimdevices.com/showthread.php?t=46271 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Not impressed with the Transporter
I recently had to send my transporter back for repairs. For the two weeks that it was out, I hooked my SB3+Bolder power supply+DAC1 up to the same setup that I usually have my transporter hooked up to: an ATI AT1502 driving a pair of Magneplanar MG3.5s. I was reminded again as to how good the SB3+DAC1 sounds. But it was kind of a relief when the transporter came back. To my ears, there was a real, if subtle, difference and which I would describe as there being more there there. Years ago, I worked as a piano tuner and I felt that I had my ears pretty well trained (no tuning machines for me, just a pair of tuning forks, a tuning hammer and my ears.) Granted, my high-freq hearing, at age 50, is not what it used to be. But I seem to prefer the sound of the transporter and I haven't regretted the investment. But, you hear what you hear. And if what you hear coming out of the transporter disappoints you, then by all means take advantage of SlimDevices' return policy. -- gharris999 gharris999's Profile: http://forums.slimdevices.com/member.php?userid=115 View this thread: http://forums.slimdevices.com/showthread.php?t=46271 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
