After all, most CDs aren't pushing the 74 min limit. On a slightly more serious note, a lot was made of the ruggedness of the CD when it was introduced, and I suspect the outer edge is more likely to suffer different problems, be it during production or through careless handling by the consumer. Using the inner part first, a mildly compromised disks will still function properly. I remember buying a compilation CD that was filled to the edge, when played the last few minutes was filled with drops and pops, and when I got it replaced it was the same. On closer inspection there were minute cracks along the outer edge. I wouldn't hazard a guess as to how these had developed, but it must have happened during manufacturing or packing.

Re: [SlimDevices: Audiophiles] Chips
The point is that rating the chips in isolation is for the most part not meaningful, the environment you place the chip in often has more impact on the result. There may be virtually no differences between two chips under ideal conditions, while two different implementations with the same chip may display a big difference. Neither of the differences is necessarily audible, but if the design is sufficiently bad it might be. alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=106575 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

Interesting observation which shows that unless you make the effort of understanding the design you may make faulty assumptions on what operations are the most demanding. Also, not all kinds of processing is equal from a noise perspective. It is quite likely that operations that require a few more cpu cycles but operate largely on cached data would cause less noise on the power supply than more IO-intensive tasks even though they might not take as much processing. -- alfista alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=91322 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] soundcheck's Touch Toolbox 3.0
Phil Leigh;689509 Wrote: The audio data in the Touch is not cached per se in the tradional sense - it is held in a FIFO ram buffer, since it is read once. Ah, yes, the term cache was maybe a poor choice (and of course I was talking about the internal cache or RAM in the CPU) but then again it was a purely theoretical excercise on how the same amount of CPU cycles might present a different amount of EMI depending on where the CPU fetches the data it is processing. My reasoning is that accessing memory external to the CPU is likely to affect the power rails to a higher degree than accessing internal RAM (or cache). This may or may not be relevant for the Touch though, mostly because I'm not all that familiar with its inner workings. I assume though that the FIFO of which you speak is a software implementation using the normal RAM, thus requiring both write and read accesses via a 32 bit DDR2 interface. The question regarding FLAC may be whether the decoding process will generate additional read/write operations to this RAM compared with WAV, or if it will perform the decoding entirely using internal memory. Either way, it may still have an edge on WAV when it comes to memory bus bandwidth. Again, all purely theoretical, I neither claim nor believe that it's really an issue. -- alfista alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=91322 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

mlsstl;673178 Wrote: I'd also point out that such a person could also buy their own 20,000-plus watt generator and have it installed in the yard away from their house and provide themselves a dedicated power source completely isolated from the mains. I would expect nothing less from anyone serious about their system. However, there are several factors that must be carefully considered. This has to be an audiophile grade generator with windings from copper cured for +500 hours in a bath of meticulously temperature controlled vintage crude oil at ridiculous pressure. Also, a precision generator must not be powered by any run of the mill diesel engine (engines with harmonic dampers are particularly ill suited for audio purposes, but that goes without saying I guess), actually any piston engine is likely to have too much torsional vibrations resulting in overtones in the output of the generator. Japanese audiophiles swear by Mazda rotary engines but recent listening tests with gas turbines from General Electric running at a speed tuned to an odd multiple of the crossover frequency of the speakers gave favorable results. It wasn't a blind test though, the leaves flying off the trees outside the window was a bit of a giveaway. Next is the choice of fuel, naturally there may be no additives that may affect the imaging or contaminate the high range the way ordinary cheap jet fuel would. Medical grade ethanol is preferred by many for it's neutral tone, while a 24 year single malt is popular for the noticably warmer glow it gives to the tube amps and you will also enjoy a slightly smoother sound from your vinyl records. Sadly, the whole idea of running your own generator falls over since there is no economically feasible method of supplying enough air of the quality required. Normal outside air varies wildly when it comes to temperature, humidity, pressure and oxygen isotope ratio, not to mention the sonically detrimental effects of certain pollen types. So far, listening tests has been constricted to 5 minute sessions, nobody has been able to provide more processed air of the necessary grade to run the gas turbine for longer periods than that. If you live in a rural area and has a less revealing system you may get away with using outside air during the month of october. Maybe one shouldn't mock this stuff though, spending money (even absolutely obscene amounts as in this case) on a power cord does in some sad way make more sense than spending them on audio grade USB cables or hard drives. -- alfista alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=91896 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
