| Audio experts help Decibel output. Would the characteristics of the signal coming off the amp be changed as it passes through the first speaker into the second? In other words, hooking two four ohms nominal rated speakers up in series isn't as simple as 2 times 4 equals 8.Hi Bruce,... | |
| What is a high end stereo SUPPOSED to sound like? 07-14-12: BryoncunninghamIn spite of the fact that the live event and the recording are, to some extent, Unknowns, many audiophiles believe they can reasonably speculate about them. Those speculations are, of course, uncertain. But their uncertain... | |
| Risk using amp Wattage than speaker rating? I second the previous comments. Probably the most common speaker damage scenario is blown tweeters resulting from the distorted signal that would be produced if an underpowered amp is asked to put out more power than it is capable of.Based on some... | |
| Audio experts help Decibel output. While doing what you are proposing may increase the longevity of the amplifier, chances are you'll get less volume, not more, unless the amp is pretty much unable to function in a reasonable manner with the 4 ohm load.Each of the series connected ... | |
| Budget USB cable? Emerson (Foster_9), thank you most kindly!Richard, thanks also. Your inputs always warrant respect, IMO, notwithstanding the fact that on some issues, such as this one, we civilly agree to disagree.Best regards,-- Al | |
| Most "Musical" sounding speaker cable under $1000 Hi Nick,Basically, if the speaker's impedance phase angle becomes significantly negative (i.e., capacitive) across a significant range of frequencies, the amount of current that the amplifier has to supply, and the amount of current that will flow... | |
| Budget USB cable? The whole thought that USB cables can sound different just sticks in my craw. From a technical standpoint, and speaking as an experienced digital and analog designer (not for audio), I would not find it at all surprising if there were sonic differ... | |
| Amp preamp impedance matching...can anyone explain? Thanks for chiming in, Bombaywalla, and saving me some time :-)I found some information specific to the CJ PV-5, though. The schematic and parts list can be found here. It can be seen that the output coupling capacitor is two capacitors in paralle... | |
| matching amps input voltage to source output volta Hi Philip,Whatever power capability you presently have, whether it is 6.25W or 25W, would increase by a factor of 4 if you changed the Nagra's sensitivity from 2 volts to 1. Doing that would double the output voltage of the amplifier for a given i... | |
| Lossless Files Vs CD's 07-11-12: Dhl93449Well, if that were completely true, tweaks like Lightstop (green dye around outer edge) would have no impact on sound quality. But many have observed they do impact sound (including myself).All of the references that I have seen ... | |
| Most "Musical" sounding speaker cable under $1000 07-11-12: SunnyjimTo Almarg, I should have checked with Acoustic Zen about other choices than their own cables, but it seemed pointless in some ways However, your point is well taken, but checking with owners of the same speaker or others that are... | |
| Lossless Files Vs CD's 07-11-12: Kijanki>2.5mm scratches along the disk are very likely causing interpolation of data. I believe that is generally true only if the scratch exceeds that length in the direction that is followed by the spiral track. A narrow scratch in ... | |
| matching amps input voltage to source output volta Pcoombs, since you are apparently using a balanced connection between the Wadia player and the Nagra power amp, an additional point that occurs to me is that on occasion I've seen inconsistencies between different manufacturers with respect to how... | |
| Amp preamp impedance matching...can anyone explain? Onhwy61, that would apply to situations where the component providing the signal is specifically designed to be able to drive 600 ohms, without a significant increase in distortion or a significant impact on bandwidth or frequency response. Most c... | |
| Amp preamp impedance matching...can anyone explain? Ideally the input impedance of the amp should be 10 or more times greater than the output impedance of the preamp, at the frequency for which preamp output impedance is highest. Otherwise audible frequency response irregularities MIGHT result. If,... |
