| What Does Holographic Sound Like? Well, this thread seems to have established at least one thing with a high degree of conclusiveness. Those having backgrounds in defense electronics constitute a diverse group. :-)Best regards,-- Al | |
| Watts up with that? Rower, thanks for your comment, but I disagree with some of your statements:Speakers are only 5% efficient, so that means the majority of the impedance is imaginary in nature and does not do work.Much of the inefficiency reflects real (resistive) ... | |
| Whats on your turntable tonight? Listened to this afternoon:Dvorak, "New World Symphony," Leonard Slatkin conducting the St. Louis Symphony Orchestra, Telarc DG-10053.Very slow tempi in the first two movements; worked for me but won't be to everyone's taste. Wonderful sonics -- o... | |
| SSD Type Drives Better? Any particular brands to recommend that are reliable? My perception has been that it is a moving target. Reliability changes as new models are introduced, technology improves, and even perhaps as manufacturers release firmware upgrades for their d... | |
| What Does Holographic Sound Like? 09-28-12: MapmanAl has deep technical knowledge in areas that are well documented and communicates clearly and consistently in a manner that I seem to understand. Also Al is not a vendor TTBOMK.Thanks very much, Mapman. Your assumption is correct ... | |
| Watts up with that? The 100 db calculation was for the pair of speakers, and reflected the 3 db increase. On the other hand, I should mention that it assumed a 6 db reduction in SPL per doubling of distance, which might be a bit pessimistic (i.e., too large a number)... | |
| Watts up with that? 09-28-12: KoestnerWould you guys think I am off by a factor of two, or possibly much larger?I have no idea. IMO, though, Ron (Rrog) correctly stated the bottom line: "The best way to find out if an amplifier is powerful enough is to listen."Some a... | |
| Watts up with that? I wouldn't count on that measurement being meaningful without having detailed information on the technical characteristics of the meter, which chances are will not be available. One important parameter being how brief a transient it is capable of ... | |
| Balanced or Not Roscoe50, the best way of interfacing a balanced output to an unbalanced input is most likely with a Jensen transformer, as explained in section 3 of this paper. Examples of those transformers are shown near the bottom of this page. They cost arou... | |
| Can I find out the output impedance of my amp? I actually think I can handle that. I have an email into Art Audio UK, I'll first see what they say.Hi Mark,If they can't provide the information for your specific amplifier, ask them what the damping factor is for the standard configuration that... | |
| Why so low? 09-26-12: RpfefI haven't heard cd transfers of these records so I have no idea if their aliveness and thrilling tonal accuracy survives the big domain switch. Has anyone out there heard both?I have two of the Sheffields in both formats, the Prokof... | |
| Balanced or Not I answered most of your question here. Concerning why manufacturers would do this, cost is certainly a major factor.Regards,-- Al | |
| Can I find out the output impedance of my amp? Hi Mark,I strongly suspect that the output impedance of the amplifier is NOT 8 ohms, and that the "Output Impedance: 4 and 8 ohm" specifications given at the Art Audio site are actually (and confusingly) referring to the speaker impedances that th... | |
| Why so low? Elizabeth is correct. I've looked at the sound waveforms of their Prokofiev "Romeo and Juliet" recording, using a computer program, and the difference in volume between the loudest notes and the softest notes is around 55 db! That corresponds to a... | |
| So how does this apply to speaker cables? Interesting article, Neil. Thanks! And I agree with your subtly stated conclusion :-)Best regards,-- Al |
