| Stack Audio-SmoothLAN Network Filter- WOW! Unfortunately not all SFPs work with all switches/converters. You should adhere to the recommended list of SFPs of the switch manufacturers. Cisco's typically require the SFP (Eprom) to be programmed so that the switch reads it. There is a huge th... | |
| why expensive streamers As @cleeds said most streaming services use TCP/IP protocol which delivers bit perfect data/files. Now why streamers sound different (if they do) is another story. | |
| Importance of clocking @lalitk Could you explain why the accuracy of the clock (which is defined by the long term stability in ppm) is as important? Genuine question. For example the most accurate clock that I know of is cesium atomic clock which is approximately 1 - ... | |
| Importance of clocking @antigrunge2 In your discussions with @nigeltheflash you are both referring to clock accuracy, I was merely pointing out that in our hobby the clock accuracy is not the most critical parameter. That's all. | |
| Importance of clocking Guys, it all depends what is understood by the term 'clock accuracy'. For example rubidium clocks have very poor short term stability, they jitter by design. This makes them totally unsuitable for a short term time base reference. Their big usag... | |
| Importance of clocking @lalitk No problems, thanks for clarifying. I love it that people are so passionate about this hobby over here. In my engineering mind an external clock in the home environment could cause more trouble ie introduce jitter, impedance mismatch, et... | |
| Importance of clocking @antigrunge2 I said I am out of this thread but I will answer you. In my case I have an older DAC that is still excellent and I am reluctant to change it but it doesn't have USB i/f. therefore I am looking for AES or SPDIF i/fs. You say USB is ... | |
| Importance of clocking @antigrunge2 I apologize for taking over your thread. It seems that I am causing few disputes that I didn't mean to. @lalitk Although I rarely post over here I have read quite a few of your views and I respect your views and experience. Hav... | |
| Importance of clocking @kijanki Yeah, I think AES will be. Now I need to find a good streamer with AES output up to 4,000 Euro. I have been going round and round this subject for far too long without making a final decision... | |
| Importance of clocking @kijanki Thank you for the response. I enjoy reading your replies since you seem to understand electronics better than most on this site. Sometimes it is difficult to have a technical conversation with people who have little knowledge even about t... | |
| Importance of clocking @kijanki Thanks for the explanation. My DAC is an older Weiss DAC202 that uses ARC. It has extensive fairly advanced PLLs (it uses a wider range digital PLL (I don't know its noise/jitter spectrum) and its output is fed to an further analog PLL t... | |
| Importance of clocking The issue with S/PDIF or AES "reclockers" is that you have two clocks arguing over what should the absolute clock rate be. The DAC is forced to take one of two approaches: Abandon it’s internal clock or attempt to keep it’s internal metronome ... | |
| Importance of clocking Andy has a very good point. In the case of SPDIF or AES the clock is embedded in the data stream is more prone to jitter therefore the clock of the source/streamer is critical and IMO could benefit from a good reclocker with a good clock cct and i... | |
| Importance of clocking Sure they do, they offer more options to the end user, you take your choice. | |
| Importance of clocking DCS, Weiss, Meitner to name a few. But you are missing the point, the external clock is much further away from the DAC IC (assuming an integrated type) than the one inside the DAC unit. You have the extra cable to feed the external clock to the DA... |
