Audio articles of interest

As i search various subjects on the web, i run across short but interesting articles that i'd like to share with others. I'm sure that you folks find articles that you would like to share on occasion also. As such, let's see if we can keep one common thread for these "finds".

As a matter of convenience for all involved, i would like to encourage those of you that contribute to this thread to try to use the "markup tags" that allows one to simply click on the link and see what the article that the was being discussed. If you don't know how to do this, there are directions directly below the section that one types in their response at. It is labeled "No html, but you may use markup tags". One can click on this link and it will tell you how to post using clickable links, etc... step by step. If you are worried that it may not work properly, try previewing your post prior to submitting it. If the link is not working properly, simply hit the "edit post" feature and correct the mistakes that you made.

I'll start off with a brief yet interesting article about a guy building and setting up a dedicated listening room that i found. I hope that others will contribute to this thread and like the idea as it gives us a chance to expand our audio horizons beyond the normally travelled paths. Sean

Sorry to drag this thread off-topic so quickly, but I don't really scan the net for the type of articles Sean describes. This link is for a site, not an article, and it's not audio-related per se, but instead of interest mostly to record collectors:

It contains hundreds of substantially complete LP discographies (unfortunately, no 45's) catagorized by record label, in chronological order, plus articles on label histories and actual label photos. Entries include catalog numbers and years, stereo or mono content, and a majority of them even include track listings. The database is also searchable. The material dealt with is limited to American popular-music labels during the rock era. A great resource - enjoy.
Here are some tweaky links (not original: a subpage of one of cdc's links), especially the stereophile articles.
Here are some more:

link to links of audio stuff
What HiFi's links to almost every audio munufacturer in existance
So if you don't need to sleep, unemployed, etc. this should keep you going :-)
Hey cdc, you implying we is some deadbeat insomniac? Ha, even if it's all true, great links! ...Aaaahh, the slings and arrows we must bear to keep threads alive or to subscribe to them for future ref...!
This is not to say that i endorse or agree with the findings / point of view of this person, but those that are interest in the differences of passive parts, especially capacitors, should take a look at this website. The author writes and tries to display variances amongst capacitors with some very interesting results. I will only add that many of the results posted here fly in the face of other test results / comparisons that i've seen. None the less, i thought it made interesting reading for those that are "worried" about such things : ) Sean
Here's another source of interesting info on "the final frontier" of trying to obtain a good sound system. While they were found on ASC's website, the main articles worth reading were about room acoustics and another about the proper selection and use of bass traps in a room. Both of these articles are reprints of Moncrieff's original articles as they appeared in International Audio Review aka "IAR". Sean
How about the Anstendig Institute for some interesting thoughts on music reproduction, mono, stereo, and the like...
Agonan :-), This site is turning me into a deadbeat but I do need sleep. If I don't start spending less time here I will be unemployed.

Another one on bi-amping that may interest some.

(As many of us know, multiamping is a subject Sean has never touched :))

OTOH, I received today a fascinating, long article (a book, in fact) that Sean had kindly copied and sent me. Thank you, Sean!
Here's an interesting article about grounding. While it available from a website that i've frequented before, i never ran into it. Steve Eddy was kind enough to post a link to it on AA and i think that it's worth checking out. That is, IF one wants to learn about AC systems and grounding. It is in PDF ( Adobe Acrobat ) format, so you'll have to deal with loading up, etc...

Grounding: what works and what doesn't.

Something else that i noticed in this article that is worth repeating. Large gauge solid copper wires ( actually flat & wide sheets like those used in Goertz speaker cables ) are more effective at conducting signals over a wider frequency range than stranded wire or braided straps. By "braided straps", i'm talking about the woven braid that looks like coaxial shielding that is commonly used for "ground strap" in automotive / dc applications.

As this article points out, there are VAST differences between what makes up a good AC and DC ground. Taking that a step further, even a good AC ground may not be a good RF ground. As such, achieving a good low resistance ground over the widest possible bandwidth is what will work optimally. After all, shunting RFI to ground and then having a ground that is not conductive at those frequencies simply turns your ground wire into an antenna to re-radiate the signal. NOT good but probably more common than most think. Sean

PS... use more solid wire, use more solid wire, use more solid wire, use more solid wire : )
Make your own mini-system, this is something I've always wanted to try:

Positive Feedback has an interesting article / interview with Steve & Janet Nugent of Empirical Audio. For those that don't know who Steve is, you may have read some of his posts here and at AA under the name of "Audioengr". Not only does this give us a chance to put faces with the names, the interview covers quite a bit of history as to Steve's very impressive technical background and how / why he designs things the way that he does. While Steve and i have shared many common beliefs / findings on several wire related subjects yet discussed them from different points of view, i now know why thanks to this article / interview. Sean
