| Imac to my dac- sounds awful? Maybe the plug-and-play USB interface chip that they used in the USB DAC is at fault. If it does not support 24/96, this is usually the clue. A better quality USB interface and associated clocking will improve this.Have you checked the utilities-M... | |
| It's 2008. Why aren't there better options ? Even if theese manufacturers developed a networked DAC, the DAC design would still be the issue. Good DAC design does not come easy. There are literally no stock DAC's on the market that I would have in my system, at any price.Also, the jitter pro... | |
| Best Sonos ZP-80 Mod? Shazam - I understand what you are trying to do. There is just no solution out there for this. Also, there are no USB converter or DAC solutions that are completely jitter insensitive IME.What you could do is use the S/PDIF or AES input on the USB... | |
| Best Sonos ZP-80 Mod? The real problem with the ZP-80 is jitter on the digital outs. It is the worst of the WiFi servers I have modded. Replacing the power supply will not fix it. It needs a new clock and redesign of the S/PDIF output path. A reclocker after it will re... | |
| Best Sonos ZP-80 Mod? Shazam - A USB out does not help things unless you are forced to go to a USB input DAC. Even these are not jitter intolerant. Most use ASRC to reduce but not eliminate jitter.I2S output to the DAC is superior because it puts the low-jitter clock c... | |
| Why use CD Transport instead of computer source Jstovall389 - WiFi will not suffer sound quality hits over USB. In fact USB is more difficult to get right. WiFi is always bit-perfect. Only jitter has to be dealt with. The only disadvantage of WiFi is some times it gets interference from wireles... | |
| Digital Playback Comparison Johnnyb53 - your understanding of USB is wrong. Except for asynchronous interfaces, most USB intefaces are synchronous, and depend on the rate of the datastream in real-time. The thing that makes some USB converters better than others is the chip ... | |
| Digital Playback Comparison Vcoheda - simple, the difference in the burned CD is that the pits are more accurately place, which results in more accurate timing, which reduces jitter over the orginal CD. Digital playback comprises the data, which is generally error-free and t... | |
| Sonos Questions Rdb001 - the Sonos is capable of even better sound than the TP with a reclocker and a good DAC. In stock form, it cannot compete though. I dont feel that the D/A chip in the TP is very musical. There are much better outboard DAC's than this, altho... | |
| What does Jitter sound like? Shadorne - this paper is more meaningless than my jitter samples. The system and music tracks used for this test was a joke. No conclusions can be drawn from this study IMO.At least with my jitter sample (requested by many on Head-Fi), you can hea... | |
| Sonos Questions Frederick21 - I agree. Even Squeezebox just launched their new Duet and it does not support 24/96. | |
| Sonos Questions Frederick21 - all manufacturers will claim this. If you compare a stock Squeezebox to a stock Sonos for instance, you will be shocked at the difference in jitter. The SB is much lower, and it still has audible jitter. The Sonos has the worst jitte... | |
| What does Jitter sound like? Shadorne - the jitter download is coming. It's in the works.Steve N. | |
| Sonos Questions What I'm saying is that its silly to spend a lot of money upgrading the power supply or cabling on a Sonos. First attack the big improvement, and that is jitter due to output circuits and clock.Of course you should use an outboard DAC.Steve N. | |
| What does Jitter sound like? "Isn't the buffer in a CD player designed to store data so that it can be processed/decoded to extract the relevant audio bit stream information so that only these "bits" can be sent to the output of the DAC?"There is minimal buffering in most CD ... |
