| 24/96 USB Input Sounds like you're describing the Benchmark DAC1 USB to a tee, including the reference to neutrality:http://www.benchmarkmedia.com/system1/digital-analog-converter/dac1-usbThere are lots of comments on it which you can find in previous threads her... | |
| sounstage too big bad thing No disrespect intended at all, just a sincere question: Are you sure you didn't have the two channels connected out of phase relative to each other, when you listened to the XLO's?Regards,-- Al | |
| 2 turntables and one phono stage - Can I??? Lew -- Not sure what you mean in your last post. There are presumably two rca plugs (for left and right), plus a turntable ground wire, at the phono amp end of the cable from each turntable. The "ground" (non-"hot") side of the cartridge output fo... | |
| Amplifier reproduction of instrument Timbre Drew -- I think that all sounds right, but when expressed to that extreme is probably applicable mainly to mid-fi and lo-fi mass market products. I think that at this point most high-end designers are aware of these issues, and it's more a matter ... | |
| 2 turntables and one phono stage - Can I??? I agree with Sid and Lew that each cartridge must absolutely not be allowed to be loaded by the other cartridge. I don't know if the Dynavector DV20X listed in your system description is the high output or low output version, but in each case you'... | |
| Amplifier reproduction of instrument Timbre Drew -- Yes, lack of phase coherence and time alignment between the drivers of multi-way speakers is also a frequent cause of problems relating to clean transient response. But excessive negative feedback in amplifiers is a separate and comparably... | |
| Amplifier reproduction of instrument Timbre Hi Drew,I think that your question is put in an exceptionally perceptive manner.One major factor that I think is relevant would be the Haas Effect:http://en.wikipedia.org/wiki/Haas_EffectBasically, our hearing mechanisms "latch on" to the leading ... | |
| Wide bandwidth = necessary? humans also have a type of wavefront detection mechanism that is independent of our freqency perception. The pre ripple trips this wavefront detector and is perceived as diminishing the detail in the music.I have long believed that our sense of he... | |
| Help me with OHM's law and output transformers Chris -- I took a look at the Pipedreams at the Nearfield Acoustics site. As you've no doubt seen, there is surprisingly little specification information there, not even the speaker impedance.But on their largest model, it looks like on each chann... | |
| 24 bit/44.1? Yes, that looks right, Bob. Basically the 16 bit number is being left-shifted 8 places, which is equivalent to multiplying by 2^8 as you indicated.The conversion from a 16-bit to a 24-bit representation is exact, but of course the additional 8 bit... | |
| 24 bit/44.1? why would you think the 8 least significant bits would be zeros rather than the most significant?Hi Bob,The "least significant bit," as you may realize, corresponds to the smallest resolution increment, while the "most significant bit" corresponds... | |
| Help me with OHM's law and output transformers Chris -- I think you are referring to speakers that have multiple drivers handling the same part of the frequency range, such as a large speaker having two or three 10 inch woofers all handling the same part of the spectrum, and perhaps multiple m... | |
| Help me with OHM's law and output transformers Chris -- If you connect the two speakers in parallel, the combined nominal impedance is 4 ohms. If you connect them in series, the combined nominal impedance is 16 ohms. Of course, depending on the speaker the actual impedance at some frequencies ... | |
| 24 bit/44.1? The SPDIF protocol provides locations in each subframe for 24 bits. They might simply (and misleadingly) be basing their statement on that, and setting the 8 least signficant bits to 0, or they might really be using some or all of those bits. Ther... | |
| Wide bandwidth = necessary? For those who haven't looked at it, I think that Stefanl's link is an excellent and very in-point medical/scientific paper. It documents a study in which "non-stationary" ultra-sonic sounds increased pleasurable brain activity in the test subjects... |
