| Watts up with that? By definition a resistor consumes the entire load placed across it.Yes. And it converts it into heat.Speakers don't so they aren't resistive loads...not anywhere near.Speakers do consume most of the power that goes into them, they just don't conve... | |
| Impact of USB 3.0 on Audio I doubt that it's possible to say, until a significant body of experimental and anecdotal evidence evolves. And I think that a distinction would need to be drawn between use of USB 3.0 to connect external drives containing music files to computers... | |
| Sub's for Magenpan 3,7 From the manual for the X350.5:Some powered subwoofers require an audio signal ground reference and their makers may suggest that a black speaker terminal is where this voltage reference might be found. On complementary designs, which would be typ... | |
| Is it possible..... No, you can't do it with an RCA to XLR adapter. See this thread. Be sure to read it to the end before reaching a conclusion.Regards,-- Al | |
| Why do digital coax cables matter? Steve, thanks very much for your comments and insights. My one comment in response is in regard to:10-06-12: Audioengr"Characteristic impedance different than 75 ohm can be very good, as Al mentioned, if it is better match for given system."Sure, ... | |
| If you had to choose: tube amp or tube pre-amp? Anyone have any thoughts the previous question about what specs to look at when making sure the amp and preamp tube are compatible? The usual concern when using a tube preamp together with a solid state power amp is impedance compatibility. Ideall... | |
| Why do digital coax cables matter? Will a cable of some determinate length not add some measurable, repeatable, non-arbitrary amount of jitter within a particular range of measurement, regardless of any jitter coming from the source component?No, absolutely not. As implied in some ... | |
| If you had to choose: tube amp or tube pre-amp? You don't necessarily think that if the Emotiva was running to a tube preamp instead of Sony's SS it would help reduce the sharpness of the music?Don't know. Depending on the particular tube preamp it might help somewhat, or it might turn out to j... | |
| If you had to choose: tube amp or tube pre-amp? The preamp built into the Emotiva gives the music a very thin, scratchy sound at higher volumes...Im not familiar with how to describe it in audiophile vernacular, but it sounds digital with no richness. So I was hoping throughing in a tube pre af... | |
| If you had to choose: tube amp or tube pre-amp? Impossible to say without knowing what speakers are being used. Depending mainly on how their impedance varies as a function of frequency, some speakers will not sound right with one type of amp or the other.It is also impossible to say without kn... | |
| Why do digital coax cables matter? Steve, thanks for your inputs. Do you feel that the following may also be significant contributors to sonic differences between S/PDIF interconnects, at least in some systems?6)Differences in noise-induced jitter, due to ground loop effects and/or... | |
| Importance of Soundstage/Imaging I strongly agree with those saying that timbre should be no. 1.Concerning openness, the author defines it differently than I've always thought of it. He refers to removal of veils, for which I think that "transparency" might be a better term. I've... | |
| connecting a sub to a 2-channel system The loading presented by the sub to the power amplifier is not the reason. To prove that, see what happens when the sub is connected but its volume setting is turned all the way down.What you are perceiving could be the result of a phasing problem... | |
| Watts up with that? As a followup to my previous post, see Figure 1 here for an example of a speaker having small phase angles (i.e., having an impedance that is pretty much resistive) across most of the spectrum. Note that the phase angle never goes below approximat... | |
| Watts up with that? 10-01-12: Rower30The dynamic range reference is from the AVERAGE SPL, not the minimum. So if your avevrage SPL is 85dB, your peak dynamic range will be 115dB, not a value most systems can manage. I had indicated that the average SPL of the recordi... |
