| Anyone use a DVD player as a front end? Bob -- Thanks for calling AudioDiffMaker to our attention. I hadn't heard of it previously.I looked through his 20 page slide presentation, though, and I'm a bit mystified as to how it is supposed to be able to reveal (or reveal the absence of) ve... | |
| Anyone use a DVD player as a front end? Al - the best digital cable supposed to be 1.5m to avoid reflections from impedance boundaries coming back straight at the edge. There are Bergeron diagrams showing what happens to edge with different propagation times and slew rates.Yes, exactly!... | |
| Anyone use a DVD player as a front end? Corrrection to the link in my previous post:http://forum.audiogon.com/cgi-bin/fr.pl?fcabl&1233206618-- Al | |
| Anyone use a DVD player as a front end? Jane -- Jitter that can be introduced at the interface between a separate transport and dac will be a sensitive function of cable length. See the comment by Tobias in the following thread, and the subsequent comments by me and others:http://forum.... | |
| Digital cable optimal length? I agree with MrDerrick. See the post by Tobias, and the subsequent comments by me and others, in this thread:http://forum.audiogon.com/cgi-bin/fr.pl?fcabl&1233206618The technical factors for digital audio transmission are completely different ... | |
| back to ask again long sorry OK, thanks Jim. Perhaps I misinterpreted Dave's post, and maybe he meant that the dedicated line does have a safety ground, and one which has a proper complete path back to earth, while it is just in the rest of the house that there are some 3-wir... | |
| power conditioning vs. power regeneration? Hi Bob -- Sort of, but I'd put it a little differently. I would say that the amplifier stages of the power amplifier are isolated from noise and other garbage that may be present on the ac line by:1) The rectification (ac to dc conversion) process... | |
| back to ask again long sorry Whoa! So the whole system (chassis ground and signal ground of all components, as well as all interconnect shields) are completely floating relative to ac hot and ac neutral.Seems to me that that is your problem!!And beyond that, I wonder if ac ne... | |
| mcintosh amps any one can explain impedance taps Thanks for pointing that out, Casouza. I hadn't realized the amp was solid state when I made my post.Regards,-- Al | |
| back to ask again long sorry Thanks for posting the pics, but they do not trigger any particular thoughts for me. Did the electrician friend make a comprehensive set of measurements of all 3 of the connections (hot, neutral, safety ground) at each of the relevant outlets, ver... | |
| New vs. old DACs - opinions? You also need to consider whether jitter rejection will be an important consideration for the DAC or no depending on your source(s). If you are not sure, then safer to go with a DAC that is more resistant to jitter from the source, like most upsam... | |
| power conditioning vs. power regeneration? Yes, in principle a power regenerator should do the best job. However, a good one, with sufficient output capability to power an amplifier and other components that may draw considerable current, will cost considerable $, and also be substantial i... | |
| power conditioning vs. power regeneration? Hi Bob,I think that what might be misleading you is the phrase "modulate the output from the power supply," which I too have seen said in various contexts.In a typical design, the internal power supply of an audio power amp is essentially not in t... | |
| back to ask again long sorry I don't get the breaking and re-establishing IC thing, this has nothing to do with power issues.Sns, there are two possible relations that I can envision, albeit somewhat vaguely:-- If a ground is missing somewhere, a component by itself (not con... | |
| When did the Hi-Fi sound mature? Shadorne -- Thanks!-- Al |
