| The difference between impedance and resistance Bob: While reading the links keep in mind that the 'phase' difference is a way of describing the special case of the transfer function for a system when the input a sine wave and where the transients have died out (steady state). | |
| The difference between impedance and resistance Bob: It goes back to basic em fields. As to inductance the motion of a charge (which is current) causes a magnetic field. If the current is varying with time the magnetic field will vary wtih time. A time varying magnetic field causes a voltage in... | |
| The difference between impedance and resistance One way of dealing with any signal is via Fourier analysis. That analysis, along with a host of other signal analysis techniques, benefit greatly from Euler's identity, without which the analysis would be unnecessarily cumbersome. There is simply ... | |
| Does the quality of a digital signal matter? Paulsax: Once the digital signal is converted back to an analog signal there can be any amount of additional amplification, filtering, etc within the CDP prior to feeding the analog signal to the preamplifier. The effect of this additional signal ... | |
| Is listening daily at an average of 85db safe? "Pro sound books" and "Audio magazines" ( assuming we are not referring to peer reviewed audiology journals) are not exactly the type of sources that should be relied upon for auditory health. | |
| What are we really trying to replicate? Mceljo: I tend to agree with you also as atmosphere for music and, for that matter, the sporting events. I have turned down free tickets to the Rose Bowl game and to NFL playoff games and when I go to the symphony, which is quite often, I listen l... | |
| What are we really trying to replicate? I agree with Opus88 that attending live concerts is wise; not only for comparison purposes but for sheer enjoyment. Now live concerts vary - mostly by genre. The striking feature of live rock concerts, (although I admit the last one I went to was ... | |
| Does the quality of a digital signal matter? To the OP: Take it from another EE; your friend is correct. Everything that matters as to signal quality occurrs before and after the digitization. You cannot do anything about what happens before the signal is digitized so if you want to improve ... | |
| Classics you can't have too many recordings of Bach's Mass in B Minor and Brandenberg concertos; Beethoven's Eroica, Fifth, and Ninth symphonies, and piano concertos; Gershwin's America in Paris and Rhapsody in Blue, Mahler's Das Lied Van Der Erde; to name a few. | |
| Is listening daily at an average of 85db safe? asking this question on an audiophile web site is not a very good idea; neither is giving someone advice in this regard. I have my own opinion, which, given my background is probaly better than 99 percent of the persons who are going to respond. C... | |
| Will there be any 'Arrow' mark in a Fuse holder? Most manufacturers do not put an arrow on the fuse holder because the polarity of the sine wave coming out of the wall socket depends on (1) whether you are above or below the equator and (2) the position of the planets at the time that you change... | |
| Sennheiser HD650 Headphone Amp I use the HD600 hooked to a Firestone Audio "Cute Series" amp with a matching power supply. Inexpensive and works well. I was unable to drive the 600 with the headphone output of a Mcintosh pream or with an E-Mu USB interface. The 600 needs a litt... | |
| Shakti Stones Do they actuall work guys. Shatki bricks are even better but not nearly as good as shatki cinder blocks. In-the-know audiophiles will want to raise the blocks to 2.5 meters above a cd player (too ensure good bass extension) and then let go directly over the cd player (while... | |
| Why not horns? basically, the wall (for the k-horns) is part of the bass horn, so not having it flush ends the lenngth of the horn at the point where it is no longer effectively one piece. It is no differentin principle than the horn that loads the midrange, but... | |
| Why not horns? Mapman: The bass extension of the k-horn depends on the length of the horn - which is the lenght of the corner in each direction. I believe that to get the full extension you need corners that extend 48 inches in each horizontal direction. False c... |
