A great article on Class D/switching amps
I dropped my subscription to TAS a while back. Can anyone offer what specific issue this article is in? Sean> 
How Do I Build a Faraday Cage?
If you want it to work OPTIMALLY, you need to use thicker materials that are solid. The cage would also be attached to a low resistance Earth ground. Aluminum is FAR less desirable than steel and to a lesser extent, copper. Using thinner materials... 
Xover parts quality,/sound difference?
Dbld: Most commercial designs are SOOOO far from being electrically optimized that just covering the basics i.e. better connections, better conductors, shorter signal path, etc... will almost always introduce better sonics. Parts tolerances and me... 
Can someone guide me as to what Single driver ??
Elvis: I've just been watching the audio detectives and learning from them, their discoveries and their mistakes. Most everything that i've ever learned and / or shared here ( or in other audio forums ) is an accumulation of information that i lea... 
Can someone guide me as to what Single driver ??
Duke, for an inexpensive driver, the Eminence Beta 12LTA offers pretty wide bandwidth and high sensitivity. Eminence has recently revamped their measuring techniques, so some of the spec's may be different than what is posted on PE's website. Lot ... 
cable dielectric cause of artificial sound
Dazzdax: I would not doubt that Audioquest's "DBS" system is based on something similar to what i'm experiencing. Without talking to Bill Low, i'm strictly guessing at that though...Tplavas: I was working with standard "foam" dielectric as found i... 
Can someone guide me as to what Single driver ??
Darkmoebius: I would not doubt that the Hammer Dynamics system works reasonably well, as i've used the same basic 12" Eminence driver in several different yet similar PA installations. I've made mention of this Eminence driver a few times when tal... 
cable dielectric cause of artificial sound
I stumbled across a very curious phenomena pertaining to cable dielectric at work the other day. Nobody that i have discussed the matter with can explain what is happening, yet they have seen the very easily measured and duplicated results that i'... 
The WORST Components for Rock and Pop Music
Xiekitchen: Most electrostatic speakers lack the dynamic output to sustain high spl's, let alone the bass that is needed to "drive" the music. On top of that, the way that most people build systems that are E-stat based may have something to do wi... 
Best way to connect 2 preamps to 1 power amp
Davidcpl: I'm not aware of any "high quality" RCA / XLR based switchboxes on the market. As for your Lexicon meeting the above criteria, your best bet would be to contact the manufacturer and ask them if they see a problem with what you want to do... 
New room, very small .Speaker Placement???
Fiberglass will work best in the corners. Check over at AA pertaining to "quick & dirty" bass traps. Sean> 
ANTI-CABLES by Paul Speltz: Anyone Using Them?
Spacing the cables further apart introduces a shift in both the nominal impedance of the cables and the tonal balance of the system. Obviously, most systems are not as "neutral" as we would like to think and / or some end users have very specific ... 
Best way to connect 2 preamps to 1 power amp
You can NOT connect two preamps to a common power amp using "Y" cables or splitters. The preamp that you are using at the time will not only see the amp as the load, but also the other preamp that isn't being used. You will definitely hear the dif... 
The WORST Components for Rock and Pop Music
Any component that sounds "lean" won't work too well for rock music. Sucks the "drive" and "energy" out of the rhythm section and kills the "growl" and "chunky" sound of the guitar. Having said that, the first brand of gear that came to my mind wa... 
recommendation for turntable vibration damping
We had similar problems in my Father's house. I ended up using some cinder blocks on top of the soil as footers, four floor joist supports and the longest 4' x 4" that i could fit into the crawlspace. The 4 x 4 was used as a brace between the top ...
