The best way to shield components from each other?
Some (most?) shielded speakers are not actually shielded due to the afore mentioned difficulties in constructing an effective magnetic shield. The trick is to take an additional magnet of equal strength and align it in the cabinet so the magnetic ... 
DC Power/AC Inverter power supply
The inverters I am familiar with don't produce a pure sine wave. But assumming that they do, the power out has to be less than the power in because nothing is 100% efficient. Since the formula for power is I x V = P (current times voltage = power)...

Cable shoot-out: Part IV
I would offer the following for your consideration. You are putting the cart before the horse. It sounds like the room is the weak link and that should be your focus at this point. Cables should be the final touch on a system after optimizing all ... 
Speaker Cables, One side longer- bad idea?
Hi Bwhite, Any job openings at your company? If you have the time to post all that at work AND get paid enough to afford this hobby, I'm in.Interesting thoughts though. 
Audio Cost Allocations
The most important component in your system is your front end. Find what like and them build your system around it.garbage in = garbage out 
Nashville Audio or Home Theater Shops
There are only two high end stores. The better one is Nicholson's (ask for Tom Berry or Larry Staples), they usually have a pair of Pipedreams set up. The other is Audio Video Environments. The last I checked they were more heavily in to the home ... 
Soudstage issue
It is pretty common to have the piano spread across the soundstage. These recordings are done with the microphones close to the piano so the perspective when they are played back is that of a person playing a piano or standing right next to it. It... 
Mark Levinson No.37 and 36s Vurs ML 39 CD Player
Don't take my word as the final answer, but it seems I remember my dealer telling me that a 39 used the same transport mechanism as the 37 and the same DACs as a 36, just in a single box. If that is true, you would be going from a 36S to a 36 plus... 
Passive VS Active crossover-What s the difference s
The job of the crossover is to divide the full range signal into ranges that the individual speakers are designed to handle. Using a two way speaker as an example, high frequencies to the tweeters, low frequencies to the woofers. A passive unit c... 
Passive Stage preamp vs Active Stage Preamp
I agree with most of the above with a few exceptions. I agree that a passive pre-amp is difficult to implement, but not "always" bettered by an active. I have tried several different combinations and have found at least one that works. It requires... 
Can someone explain db sensitivity?
Ok, after doing some research, I now think the 10 times power part of my answer was wrong. I don't know where I got that but I know I've heard it before. Must be the 10 times reserve power mentioned above. Sorry for the confusion.I also agree with... 
Can someone explain db sensitivity?
Note to Aragain. I beg to differ. I believe you are confusing percieved loudness as measured in dB with amplifier power, which is also measured in dB although they are two different things. The 90dB versus 87dB is the output loudness from the spea... 
Can someone explain db sensitivity?
The higher the sensitivity, the louder a speaker will play with the same input. This loudness is measured in dB. A difference of 3 dB is twice as loud. So a 90dB speaker will play twice as loud as an 87dB speaker with the same input.The "what is g...
