Re: [SlimDevices: Audiophiles] Volume regulation of transporter?
How come no one is concerned by the loud pops if you plug it directly into the amp. Try rebooting your pc, or simply stop the slimserver. That will cause Transporter to go into total shutdown even I set it to leave audio always on. This makes one hell of a pop.

Sure, but I'm not comparing to tinny bookshelf speakers--I've had B&W Nautilus 803s , Vandersteen 2ce signatures, and a huge pair of Klipsches (can't recall the model) at various points and I've heard a lot of other nice setups with excellent low-end. There's a big difference between a pair of speakers that can actually reveal the low-end and one that overemphasizes it. Again, it's ultimately not a huge point and the audioengines are a very nice piece of kit (as I said, I like them enough that I'm probably going to get another pair). Compared to other products in their category (powered, small, and not incredibly spendy) they sound very nice indeed. -- SumnerH SumnerH's Profile: http://forums.slimdevices.com/member.php?userid=13035 View this thread: http://forums.slimdevices.com/showthread.php?t=39300 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Lite Audio DAC-60 thinking about getting one..
G, How do you know it is the DAC chips that are bad? It could well be some other part or parts. Also, even if you can visually see burning on a particular chip, it doesn't mean other parts weren't nuked at the same time. You can replace them, but be aware it will be "challenging". The DACs are very small and are surface mounted to the board. Normal soldering techniques won't work. Mouser is supposed to be getting more PCM1704U-Ks in during November. Make sure you get the K version. If you want to sell the broken DAC60, I'd consider buying it. -- Cappy Cappy's Profile: http://forums.slimdevices.com/member.php?userid=13710 View this thread: http://forums.slimdevices.com/showthread.php?t=20789 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

When the CD format was established, 16 bit resoltution was past what the technology of the day could realistically provide to consumers. The existing EIAJ standard for digital audio defined a 14-bit format; indeed early Magnavox CD players used 14 bit DACs. I believe Philips was arguing for 14-bits, but Sony held out for 16-bit, and eventually Sony won. But the 14-bit infuence is very prevalent in the era. Even Sony's PCM-F1-type recorders were switchable between 14-bit EIAJ recording mode and a 16-bit mode, which replaced some of the error correction bits with data bits. The point is that back in the day, formats with higher dynamic range than 16 bits were not even on the radar. It was a struggle to get even 16-bits back then. Remember also that the CD standard was developed in the pre-PC, pre-IEEE-floating-point era. Microcomputer chips existed (8080, Z80, 6502, etc) but none was sufficiently powerful for processing floating point at the speeds required. Also remember that the IEEE754 floating point standard had not been adopted then (it was one of several FP representations which were implemented in software), so hardware floating point processors had not been developed for the consumer market. Also, I don't recall ANY 16-bit float representation in general; most were 32-bit at the time. That said, at the time there were non-linear digital audio formats in use for telephony, mu-Law and A-Law. Maybe a better question is why did the CD standard pick 16-bit linear PCM instead of extending one of the telephony standards. -- Timothy Stockman Timothy Stockman's Profile: http://forums.slimdevices.com/member.php?userid=8867 View this thread: http://forums.slimdevices.com/showthread.php?t=39611 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

On the other hand if you have 1 devided by something you have a > situation where you assume a definite limit which can not be assumed for > loudness. In fact, PCM digital audio, as the industry has defined it, *does* have a definite upper limit, 0 dBFS; actual audio levels are specified, for example, as -10 dBFS, etc. The fact that additional resolution gets added on at the bottom and not the top is a matter of industry definition, not theory. This is done so that a signal with 8 bits, 16 bits and 24 bits of resolution can all express the same maximum loudness, however more resolution can give a more accurate representation of a low-level signal. If this was not done, one would have to turn up the volume big-time when switching from 8-bit playback to 16-bit playback, or from 16-bit playback to 24-bit playback. There are special cases however, where extra bits of resolution do get added on at the top. One example is HDCD, which defines that besides adding resolution the normal way at the bottom, it has a peak companding mode that adds exactly one extra bit at the top. In HDCD playback hardware, normal audio that is not HDCD encoded is attenuated by 6 dB (1 bit) so it will better approximate the percieved loudness of material encoded with HDCD peak extension. One of our members here has posted an HDCD decoder program for WAV files, and indeed it does just this if given a non-HDCD file, reduce the level by 1 bit. In practice, it also reduces the average level of most encoded discs by close to 6 dB also, because, when HDCD is used properly, the audio signal doesn't spend a lot of time in the "peak extension" companding region.

[SlimDevices: Audiophiles] SB3 + Lite DAC60 vs Transporter

Re: [SlimDevices: Audiophiles] New 3rd party power supply
Well, my first though is that $259 seems rather a lot if all you're trying to achieve is elimination of the potential RF effect of a switching PSU. I think I paid around $40 for the one unit I have, attached to an SB2. Incidentally, the answer to the question "does the linear PSU make a difference in this particular system" is a resounding yes: no need for DBT!! The reason is that the SB2 is in close proximity to an FM radio, and the switching PSU makes the radio completely (and I do mean completely) unusable. Moving over to a linear PSU made it usable again. I would consider this test to be proof of the proposition that "the switching PSU throws out RF noise that *MAY* affect other components nearby". Whether that effect would show up as a subtle degradation of audio quality, as claimed by a number of listeners, I couldn't possibly say.
