  1. The side-wall reflections are an important part of the 2 channel stereo image. Diffusion on the side-wall is OK, but not absorbers. But with 5.1 channels they are OK. There was a product that placed an absorber between the speakers. With the edge pointed at the listener (rather than the flat side). It was claimed to increase separation.
  2. What are the betting odds on the NFL getting all the games finished in 17 weeks? how about 18 weeks?
  3. In this case, he is stretching it orders of magnitude. Unless the tiny ones nasty problems it won't be helpful. Low order distortion or background noise will have little impact. * * * * * * * * * * * even adding two different noise sources of the same level only increases the total noise by 1.4142.
  4. It would take a skilled engineer with modern high end test equipment and a lot of spare time to possibly measure those distortions. But any technician with half century old test equipment could easily measure distortion and other errors in your unit. There are orders of magnitude differences involved.
  5. Nope. It's only cables with low loop/series inductance that come close.
  6. With any decent 4 terminal Ohm meter. I'm long retired and I have a meter on my workbench with a 100 micro Ohm resolution. And there are other methods but they take more skill. How do you know the the conductors that you are using are accurately labeled? A magazine measured several 12AWG speaker cables some years ago. Few were actually 12AWG (by UL spec).

  9. For any hi-fi speakers (above the budget range) worth considering, that info should be available somewhere. If it's not available, scratch that speaker of the list.
  10. There are standard methodology tests and have been so for decades. I'm sure that using standard tests, there will be measured frequency response differences in those many cables. But those tests will be repeatable & reproducible and have quantifiable results. And no, many details in his test were not set out.
  11. I'm sure that was a typo. He meant 'Impedance' not 'Capacitance'.
  12. A countless number of them. Almost all SET amplifiers meet the definition along with many tube pre-amps. In the pro audio world. Sometimes mic's and mic input transformers combinations are chosen for their special sound.
  13. Don't you have an Ohm meter? What about all the other cables?
  14. Yes, but unless you have very low impedance speakers, you are paying for current (not power) that you will never use. For low impedance speakers: Lots of current is good. DC supply voltages don't matter. For high impedance speakers: Higher DC supply voltages are good. Current doesn't matter.
