| John Dunlavy On "Cable Nonsense" I presume the meter was FIXED on to a stand or tripod, and that the equipment was not changed in setting or other value. I think you said that you ran several iterations of the test to verify results - which would tend to verify them. One also has... | |
| Mixing Silver and Copper cables -- Good or bad?? Before you decide what did what you need to answer a few questions -did you buy or make the cables?are they *identical* in all facets except for the material of the wire itself?If there are differences, you can not be sure that it is the metal dif... | |
| Mixing Silver and Copper cables -- Good or bad?? The general wisdom on Silver (tinkly top) vs. Copper (fuller, but not as clear) sound is usually correct, as far as it goes.There is NO transition between the two cables used in the same system, since they don't physically touch. The dealer may ha... | |
| John Dunlavy On "Cable Nonsense" Geez...It's hard to follow threads on a non-threaded heirachy site!Anyhow JHunter suggested the pink noise method for testing cable "differences." I certainly do like to use pink noise for discerning very small effects. You can use pink noise when... | |
| John Dunlavy On "Cable Nonsense" Frap's post is interesting and points out a real issue.There are two intersecting factors in his turntable story. The first is that since phono has the lowest signal levels that you are likely to find in any system, they seem to be most sensitive ... | |
| Which IC is more important? A chain is only as strong as its weakest link...This is the wisdom for all hi-fi. However, having said that, the lower the level of the signal - turntable to phono - the more *sensitive* it is to cable effects. You can easily see how this works by... | |
| Damping Factor The Crown Macro Tech series has a DF of about 30,000.Most tube amps can't get a low Df because of the output transformer being inherently "stuck" at one impedance. There are many tube amps with much more feedback than some solid state designs, but... | |
| Software spectrum analyzer If you check the back issues of TAA the IMP articles give you the infor on the Panasonic WM-60 (I think) electret mic element that is damn flat for I think that Digi-Key sells the mics,and Bill Waslo of Liberty Instrument sells them calibrated, as... | |

| John Dunlavy On "Cable Nonsense" JHunter asked...- are all the systems used for published DBTs inadequate?Yes, IMHO, based upon those articles that I have read (which may or may not be all of them) the systems that were used are/were wholly inadquate on a number of levels.There a... | |
| John Dunlavy On "Cable Nonsense" ... internal processing...By internal processing I do not mean that familiarity leads to recognition - although there is an element of "ear training" that plays a role in how we all hear. The question is not familliarity as much as how much intern... | |
| John Dunlavy On "Cable Nonsense" JHunter wrote...--> Bear is up to his usual "debating" tactics. If decades+ of established acoustics methodology and all the evidence (from scientifically valid testing) goes against you, then just claim that the testers don't have a system wit... | |
| John Dunlavy On "Cable Nonsense" No way to quote an earlier post...Unfortunately there's no way to *quote* a previous postin order to respond - like you can do on a usenet newsgroup by hittin the "reply" button... Grungle, I was responding toyour post and copied parts of it in or... | |
