| Is bi amping really a trade off? I'll assume that each component in the speaker is running in parallel to the other. If that is right, then (to keep things simple) can I say that each component has a resistance of 16 ohms so that when I run the components in parallel I have a spe... | |
| Best Speaker under $3K - New or Used There's a nice clearance sale right now at Audio Advisor on the MartinLogan Source, at $1347.50/pr + shipping (new), and the MartinLogan Vista, at $2999/pr + shipping (new). I haven't heard them, but they would certainly be among those I would wan... | |
| Anyone know what amp this is? Any ideas what the speakers are?Jim Rogers JR149's, British, similar to the LS3/5a except for the cabinet.http://www.mcmullon.com/icollect/hi_fi/jim_rodgers/jr_review.htmNote: I believe the reference is incorrect in spelling the name as "rodgers";... | |
| Jitter and 75ohm cable length With this cable manufacturer, I can order any length, is there an "ideal" length, or are there too many system dependencies to determine this?Summarizing all that has been said, I would put it that a length of 1.5 meters (which is virtually the sa... | |
| Jitter and 75ohm cable length Rpg, 1 meter is about 39.37 inches. And of course 12 inches = 1 foot. Therefore 3' is about (12 x 3)/39.37 = 0.91 meters, which DOES NOT conform to the length recommendation.6' is about (12 x 6)/39.37 = 1.83 meters, which DOES conform to the lengt... | |
| Jitter and 75ohm cable length I'm not sure what happens with balanced cables. Impedance is 110 ohm and voltage levels are much higher but at the same time slew rate is likely higher and reflection induced jitter taking over noise induced jitter. Maybe Al can help here?I'm not ... | |
| Jitter and 75ohm cable length If one suspects they have a Jitter problem with their system, how might it manifest it's impact on the analog output. I second Kijanki's excellent comments, and I would add the following thoughts, which I composed before seeing his response:IMO it... | |
| Jitter and 75ohm cable length Clever experiment, taking advantage of the fact that the CDP has digital inputs!I have no knowledge as to how practical it might be to have the Kimber cable re-terminated with Canare's, but why bother? If the 3' HAVE/Canare sounds just about ident... | |
| Jitter and 75ohm cable length I came across a number of articles saying you should use at least 1.5M of cable to reduce reflections in the cable so as to not harm the clock signal, yet an RF engineer said this was a bunch of "Bunk" and 1M would be better, in fact he said the s... | |
| Chasing 60 hz hum And in how many cases can the problem be blamed on the manufacture of equipment for not checking for the proper AC orientation of the primary winding of the transformer.....Good question. I don't know the answer, of course, but it wouldn't surpris... | |
| Chasing 60 hz hum 11-10-11: KirkusActually I've experienced at least as many grounding-related problems with "double-insulated" equipment as those with safety grounds. This is because they still have leakage reactances in their power transformers, and thus AC-relat... | |
| Top 10 Snafus to avoid when building a good rig Attributing sonic characteristics to components or cables that are in fact the result of INTERACTIONS between those components or cables and what they are connected to, and/or other parts of the system. Seconding Ahendler's comment, I believe that... | |
| Explain speaker cable resistance, capacitacance? The resistances of both cables are low enough to be insignificant for typical lengths. The resistance of cable 1 might become marginally significant if cable length is particularly long AND the speakers have particularly low impedance (I believe t... | |
| Chasing 60 hz hum Thanks again, Jim. I read through the entire thread, which unfortunately fails to reach consensus, due as I see it to personality conflicts getting in the way of what could have been very constructive exchanges. Which is particularly unfortunate c... | |
| Chasing 60 hz hum Thanks, Jim. I've never been able to figure out how to navigate through long threads at AA in an efficient non-confusing manner :-), and in trying to do so in the thread you linked to I just encountered a lot of disagreement and arguing.In any eve... |
