| Upsampling. Truth vs Marketing Pabelson...According to Nyquist, just two (error free) samples per cycle will perfectly recover a sine wave. But, in this error-prone nonsinusoidal world, where I played with digital data stream representations of analog waveforms (non audio), exp... | |
| 1st,2nd,3rd order crossovers,etc The 4th order Linkwitz is particularly well suited to line level electronic crossovers (but overly complex and costly for a passive crossover). Apart from that, every variation of crossover has its advocates, and detractors. Some say that a 0th or... | |
| High speed internet via electrical power lines For info see....www.global-instruments.com.I have suggested that audiophiles might like to use this device to test their AC power conditioning equipment. | |
| power amplifiers with ICEpower module An alternate to the ICE module is the TriPath module, for which, unlike ICE, there is a good bit of technical info available on the web. Naturally, the TriPath folk say their approach is best, as do the ICE folk. IMHO it probably depends on what y... | |
| High speed internet via electrical power lines Repeating something I have noted before...I bought and installed a device that deliberately puts pulses on the power lines which supposedly keeps mice out of your walls. (So far I think this really does work, and it is based on some solid research... | |
| Upsampling. Truth vs Marketing Sean....Homework is to read.. http://en.wikipedia.org/wiki/Reed-Solomon_error_correctionTest on Monday :-) | |
| Upsampling. Truth vs Marketing Bombaywalla...Your check is in the mail :-) | |
| Upsampling. Truth vs Marketing Sean...The sampling (your first set of dots) is at 44.1KHz. The highest audio information that exists at this sampling rate is around 20KHz, and at this frequency the music signal amplitude is very small. Therefore, unless the signal is momentaril... | |
| Someone w Experience Active/Passive Biamping I am (1)..a strong advocate of biamping, and (2) owner of MG1.6 speakers. In spite of this I suggest that biamping the MG1.6, between the woofer and tweeter panels may not be the best thing to do. (Biamping between a subwoofer and the MG1.6, what ... | |
| I can't taste my beer...or hear my cables This is your own fault for drinking "mass market" beer. | |
| Upsampling. Truth vs Marketing The term "Error Correction" applies to a scheme where redundant data is combined with the information in such a way that a decoding algorithm can recover the original information WITHOUT ANY LOSS, provided that the number of transmission errors, a... | |
| Upsampling. Truth vs Marketing Phillips used 4 times oversampling in their first CD players so that they could achieve 16 bit accuracy from a 14 bit D/A. At that time, 16 bit D/A, as used by Sony, were lousy, but the 14 bit units that Phillips used were good. The really cool pa... | |
| New Magnepan 1.6's vs. old IIIA's The MG1.6 reflects newer Maggie technology. | |
| Blind Power Cord Test & results Drubin...You are brave! Hold fast to your beliefs, even as they tie you to the stake, and light off the straw. | |
| Blind Power Cord Test & results Is everyone familiar with the old Stereophile Test CD where Gordon Holt reads his essay "Why Hi-Fi experts disagree"? As he reads through his piece he uses 14 different microphones. The differences in the sonic characteristics are huge. If the sou... |
