| Cartridge Loading for a phono pre amp Just another bit of food for thought. Say that the effect of back emf is in fact a change (increase) in the effective stiffness of the cantilever assembly. Does that matter? Is a higher stiffness a good or a bad thing? Equivalent circuit of a ph... | |
| Cartridge Loading for a phono pre amp I was the one who wrote previously about Faraday's Law and Lenz's law in support of Carr's assertion. For your information, I have designed DIY phono stages that embody the characteristics that he espouses- very high supersonic overload character... | |
| High end stereo preamps? Worth it? What makes them worth it? What qualities, preferably not expressed in purely subjective terms, makes a high end preamp that?If I were to observe that a well designed $300 DIY preamp was indistinguishable in group blind testing from a Halcro DM10,... | |
| High end stereo preamps? Worth it? If you're into DIY you can build a preamp pretty cheaply that matches, and in some ways exceeds, the specs of any of the high end preamps, and has a sterling reputation for audio quality.https://audiokarma.org/forums/index.php?threads/high-gain-op... | |
| Would switching amps make a big difference? I have a pair of ML Montis. The impedance curve is quite complex, going from c.3k real at DC, to capacitive, to inductive at the crossover (c. 340Hz) to capacitive, to entirely real at c. 20kHz (0.9ohms) to inductive.Over most of the audio freque... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Yes, many CDs are just dross, while a few are quite magical.This applies also to high res recordings, but as always caveat emptor.I know of one download that on my system sounds noticeably superior to the live performance of the same piece with th... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Agreed. My point is that the loss of a packet results in a discontinuity in the signal. In my experience such an event is audibly catastrophic and not in the least subtle and does not require audiophilese to describe.USB interfaces will report pac... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste A sufficiently corrupted data stream cannot be reconstructed at the receiving end, but the corrupted packets can be identified and dropped.This is quite audible and unmistakable. It does not result in the loss of ambience or differences in top hat... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Download your digital media onto a computer. The ripping process includes CRC checks for bit perfection. That way you can be certain that the bits out are what was intended to be recorded on the original medium and any discrepancies will be flagge... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste I'm not using technical jargon to obscure the issues. Quite the contrary.I'm happy to explain, however I'm also trying to avoid being condescending (and imprecise) in avoiding its use. Sometimes terms with precise meanings are necessary to add cla... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Stochastic is random, such as the addition of noise to a voltage level.Deterministic is due to the interference of the pulses (they're usually called symbols) with each other due to the fact that the bandwidth of the interconnect is not infinite a... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Again, the fact that the input sequence is not perfectly timed is not relevant providing the data recovery circuitry/algorithms are able to cope with the imperfections. The use of data corrections (CRCs etc) can ensure bit perfect output sequence ... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste One other thing that needs clarification- the concepts of bit perfect and low jitter are NOT homomorphic.Bit perfect simply means that the recovered output data sequence is the same as the original input sequence- which in turn means that the reco... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Incidentally, the same kinds of circuits/techniques are used to recover data for high speed data links such as is used on the backbone of the internet. The jitter requirements for those applications are orders of magnitude lower than the needs of ... | |
| The Absolute Sound "review" of USB cable reads suspiciously like a press releaste Perhaps you view it that way. I do not. CD readback is imperfect because there are mechanical and optical imperfections in the recording and playback processes that result in timing issues and there also is stochastic jitter. These processes are i... |
