| Slow speaker cables? 12-11-12: CsontosSome of the best sounding amps have limited bandwidth. I don't understand how greater high frequency extension="faster". Is it not rise time that ultimately determines the perceived speed of the amp at the upper end of the scale? ... | |
| Slow speaker cables? Differences in inductance can, at least to a slight degree, affect frequency response in the upper treble region, especially if the impedance of the speaker is low at those frequencies. Greater high frequency extension = "faster."Differences in re... | |
| Left channel fading in and out Marek, nonetheless I still find it hard to conceive of how a fault in the speaker could result in crackling from the tweeter when the volume control is turned all the way down. The likely cause of that kind of symptom would be a problem in either ... | |
| Why does the copy sound better than the original Perhaps you can think of a scientific reason(s) why you heard differences when there were no differences between the data.....Geoff, I (and also Neil, Nsgarch) already presented exactly those reasons. All of the effects that are discussed in my p... | |
| Static electricity: Unique to Vinyl Systems? If I have to shut off every light in the house and disconnect all digital sources every time I want to spin a record, then I'm done playing vinyl.Hopefully it is only one of those things that is causing the problem. After turning everything off, i... | |
| Judy Collins Her original 1967 recording of Joni Mitchell's "Both Sides Now" (not the re-recording she did some time later) has always been high on my list of all time favorite popular recordings.Best regards,-- Al | |
| Audio Technica AT150MLX finally gets some respect Most moving magnet cartridges have a recommended load capacitance range specified by the manufacturer. For the AT150MLX the recommended range is 100 to 200 pf (picofarads), as can be seen here.That figure represents the total load capacitance seen... | |
| Static electricity: Unique to Vinyl Systems? Yes, as Marakanetz indicated since the voltage levels provided by phono cartridges are vastly lower than those provided by digital sources, and are therefore amplified by vastly greater amounts, vinyl sources are much more susceptible to the effec... | |
| Why does the copy sound better than the original One more thing I should add to the description I provided yesterday of the experiment I performed:While for several reasons I had high confidence that the copies I created contained bit-perfect replicas of the digital data on the original CD's, to... | |
| Static electricity: Unique to Vinyl Systems? Sounds like pickup of RFI (Radio Frequency Interference) to me. Try turning off all fluorescent lights, including compact fluorescents that fit in incandescent fixtures, as well as all dimmer switches which may be in the house, and anything else t... | |
| pre/power matching? Mofi, thanks for linking to my post. As I indicated there, and as you realize but others may not, it is not as simple as taking the two published numbers and seeing if they differ by a factor of 10 or more. The published impedance numbers are typi... | |
| Left channel fading in and out If it's a tube, would it be one of the power tubes or the input/driver or line stage tubes? Don't know; could be any of the above, or something else. The fact that crackling occurred with the volume control all the way down, though, most likely in... | |
| Left channel fading in and out Hi Marek,A passive speaker (one that does not have a built-in amplifier, and an AC plug that plugs into the wall outlet) cannot make any sound without a signal being sent into it. And if the volume control is all the way down, there should be no s... | |
| Why does the copy sound better than the original 12-09-12: GeoffkaitI suppose one might ask, how can you say the differences were "extremely small," just barely perceptible on certain notes, yet in the same breath say the original was "clearly better than the copy." The results do not appear to ... | |
| Why does the copy sound better than the original Jim (Jea48), I've done my comparison. Consistent with your suggestions as to what kinds of material should be used I've duplicated the following CD's, and compared the particular selections on them that are indicated below:1)Chopin's Piano Sonata ... |
