Would this fix a scratched CD?
It depends on whether the scratches are just on the surface, where the stuff might help, or deep enough to destroy the pits that represent the "ones" and "zeros". Of course, the error correcting encoding of the redbook CD will "fix" quite long dis... 
Best bargain for speaker that can offer top sound
At any price level, Magneplanar speakers excel in value (quality per $). If their size and shape is acceptable they are the best. (IMHO of course). 
"Pro" Amp to Drive Thiels
Some amps designed for professional sound work are well suited to home audio. The key word here is "some". There once was a time when all pro sound amps had poor sound quality, but things have changed. Audiophiles who dispute this are stuck in the... 
Does this speaker exist or am I being ridiculous?
KLH 12 which cost me about $800 for a pair back in the 1960's. They would fit your description perfectly, except the price! 
Empire 698 + AT440mla = vinyl bliss for $500
Agreed...the Empire 598 and 698 turntables can run with the best of them. Just don't get no respect. 
How to battery power?
For less a grand you could get a CarverPro ZR1600, 600 watts/channel into 4 ohms. And no money will be needed to create a dc power supply. 
Best speakers for off-axis listening
Bose 901 (yes really!) There may be other things you dislike about them, but, when placed in front of the proper kind of wall (rough brick) they do create a huge sound stage.My speakers are Maggies, and I have three in the front, but one thing I l... 
Shouldn't the Bass be felt? Duh
Jaybo...Point well taken that audiophiles, and store demos, usually focus on imaging, and that is best exhibited by small speakers of limited LF extension. I have come to realize that "superb imaging" with that female vocalist somehow levitated in... 
Radical thought- Use 2 pair of speakers
Tarsando...It was 1956 when I heard the Bose system at MIT...not 1961. (I mixed up dates of high school graduation and college!) If you google "sweet sixteen speaker" you will find that it was Jan 1961. You will also see a lot of interesting info ... 
Hearing above 15kHz
Although you can't hear a pure sine wave test tone above 15KHz you probably can sense 15 KHz roll off. A 10 KHz signal (for example) which is not a sine wave may have a wavefront steeper than a 15KHz sine wave. Based on my own (68 yr) ears I think... 
Shouldn't the Bass be felt? Duh
Basically I agree with Shadorne that multiple large drivers (in sealed enclosures) is the way to go. I have such a SW system installed as part of my house, and therefore no huge enclosures are visible. However, I must admit that I have heard some ... 
Shouldn't the Bass be felt? Duh
Some music simply has no low bass. When such music is played on a system with great LF extension it may not sound as good as when played on a system with less bass. This is because all recordings have some extreme LF noise, and if there is no LF m... 
Buffered Pre-out? What is it?
A buffer stage has a gain of 1 (or sometimes a slight attenuation). In general such a low gain circuit, either a tube (cathode follower) or a transistor, has virtually no distortion... certainly way less than the associated gain stages. A buffer o... 
another polarity riddle
If you have access to a spectrum analyser, when playing white noise it will show a deep notch at the crossover frequency if the drivers are out of phase. 
Radical thought- Use 2 pair of speakers
Tarsando...Professor Bose had a 24-driver (mono) system in the MIT music library in 1961. I don't know when the "sweet 16" project was published.The Megaline speakers which Albertporter praises are described as a "line array". (Line arrays can sou...
