What does Flat Earth mean in audio circles?
For most practical purposes, the earth is flat.

These speaker may sound great, but they should not be called "planar". 
Can any multi-channel amp be bridged?
Audiobomber...Also called the Dynaco matrix multichannel setup, and they sold hardware to facilitate its setup. They derived a center front channel by using a Y connection of the front Left and Right with the return through the center. What I did ... 
someone please explain direct coupled amps
Clueless got it right...we are talking about interstage coupling capacitors being eliminated. A Direct coupled amp has response down to DC: which means that if you put a constant 1 volt on the input you will get a constant 25 volts (or so) at the ... 
Do cd's store a more exact copy of sound than LP's
One violin or a hundred violins, there is only one signal (voltage variation over time) per channel. The fidelity with which this analog signal can be represented by a series of numbers (voltages at times) which is the digital method, is precisely... 
Can any multi-channel amp be bridged?
When you bridge a stereo amp, you drive each individual amp with the same signal, but one signal has inverted phase. Note that this makes for a more steady draw from the plus and minus power supplies. Some amps (like the Dynaco ST120 of long ago) ... 
DYI Speakers. How good can they be?
Rkeman...I agree that Madisound Kits are great. I have three Dynaudio Gemini from Madisound, which are very good (for a box). However, I don't consider assembly of a Madisound kit as true DIY. 
Recommendation for multi-ch pre/pro
Rotel 1066. Mine works great. Few $. 
Cross over frequency ???
All of the above is good advise and sound theory. Give it a try. However, my experience has led me to a somewhat different approach.First, turn off the main speakers and, with the crossover set to 90 Hz or thereabouts, listen to some music. "What ... 
DYI Speakers. How good can they be?
When I got into this hobby, virtually all speakers were DIY. You bought the drivers of your choice, and used plans put out by the manufacturers to build a cabinet. There were some good cabinet kits. Electrovoice was one that I put my Warfedale 12"... 
Maggie 3.6R performance dilemma..
Sean...Please clarify. Are you in favor of half-baked science? Or do you reject good science and perceptive instinct? 
Gilmore Audio planars revealed
There are people who say that a solid state "watt" is different from a tube "watt". Maybe these are some different kind of dB. 
Maggie 3.6R performance dilemma..
Sean... Science is good. Instinct is good. What's bad is when half-baked science is trotted out to "prove" someone's instinct. 
Rate these on order of importance:
Unsound...Since when do audiophiles agree on anything?

Lugnut...What if the aerogel were made with helium in it instead of air? Maybe we will need speaker hold-down cables instead of cones!
