Negative feedback, voltage and output impedance
Sean...Analogies can get you in trouble! One popular management approach today is the "self-directed workforce" where little or no supervision is exercised at the day to day level, and the only thing that is supervised is the overall product going... 
Abandonning Powered Speakers - Why?
Johnmcelfresh...Your write up describes the advantages of line level electronic crossovers, which I have used with biamplification for decades. Electronic crossovers and biamplification don't require that the elecrtonics be built into the speaker.... 
Current Trends in multi thousand dollar speakers
Sean...As you point out "pro" speaker systems are vented and produce lots of boomy bass. However, I notice that the majority of people on Audiogon seem to listen mostly to pop music. It is logical that their music should sound "right" to them thro... 
Abandonning Powered Speakers - Why?
Of course, "monoblocks" are almost the same thing. 
Digital Direct TV vs HD via Cable
Edesilva...The dish has a built-in level, and the adjustments have angular scales, so all you need is a boy scout compass. Clue me in...what is the drinking straw for? 
Digital Direct TV vs HD via Cable
If comparing satelite networks, (Direct TV vs Dish Network) check into the dish angles for your locality. Where I live, Direct TV has an elevation angle of 30 degrees, whereas the Dish Network needs 11 degrees. (I don't know why they are different... 
Impendance - Resistance & the story of "Z"
Sean.... B+..... See me after class. 
Abandonning Powered Speakers - Why?
Digital power amps, that generate little heat, may make speakers with built in amps more practical. The speakers could be fed ones and zeros via a fiber optic, (and 115vac). This could be carried to an extreme, where each driver has a couple of tr... 
Sub crossover frequency
Yes, use two subwoofers, and experiment with crossover frequency. I think that setting this frequency according to how low your main speakers can go is not necessarily best. Even a speaker capable of response well below 80 Hz may sound better when... 
Are the Empire Turntables any good?
About the two-piece platter...this was cited as a good thing. Does anyone remember why? 
Negative feedback, voltage and output impedance
Sean's leaky boat analogy is not appropriate. He is all wet :) If we must have an analogy, consider the task of steering your car around a curvy road. First you turn the steering wheel. Then your eyes notice that you are drifting into the opposite... 
Digital Direct TV vs HD via Cable
Edesilva...You are absolutely right that the local cable provider can make or break cable, and your house's suitability for dish location can make or break satelite.I bought my own satelite hardware and installed it myself without any problem what... 
HDTV plasmas with 4000:1 contrast ratio.
Reubent...The wall mount (or a stand) and DVI interface module are worth about $375. So you would be paying $425 for the tuner and the speakers. Edesilva...The DLP sets are very good, but they are about 19" deep, and my setup really needed the 4" ... 
Are the Empire Turntables any good?
Robbyg...That's funny. Mine was quite immune to vibration. I credited the balanced arm (downforce by a spring) mounted on a softly suspended subchassis with the platter so that they moved together. Mine was located in a solidly constructed alcove,... 
Digital Direct TV vs HD via Cable
I have Direct TV and also cable, digital for some channels.I do not have a HD plasma, (my receiver is HD) but the one I have looks good to my old eyes, and was soft on the wallet. Observations are:HD programs look better than regular ones, even wi...
