| Why manufactures don´t burn in their amps and ... Power cords are important when it comes to high power output devices.True. But along the lines of Mitch2's comment, all of the effects mentioned in Ralph's post can be avoided simply by having adequately low resistance in the path between outlet a... | |
| E sata or Sata to FireWire Assuming the BlueRay drive is in the standard 5.25 inch form factor, and has a sata interface, just purchase an external enclosure that has a sata internal interface, and a firewire external interface. There are lots of those available at NewEgg.c... | |
| Unbalanced pre out to balanced amp in Ralph, I think Bob raises a valid concern. This is basically a 1:1 transformer, not a transformer with a significant step-down ratio (which would obviously be inappropriate for a line-level interface).So while adding a 600 ohm resistor to the seco... | |
| Tube preamp and McCormack DNA-500 I also need 2 pairs of preamp outs.Keep in mind that most (though not all) preamps with two sets of output jacks simply jumper them together, at the connectors, just inside of the rear panel. A relatively small number of preamps provide separate b... | |
| Hertz Meter Reading Device Thanks Al & Shadorne. The point I was sort of alluding to is that it seems to me that attempting to do level matching by ear, we would end up with the sub's level set too high. Thus, the sub would call attention to itself and/or sound boomy.Ye... | |
| Hertz Meter Reading Device Hi Bob,Those are logical questions, and the answer to the first one is that if the system reproduces the music in a neutral manner, with flat frequency response, then the ear will hear it similarly to how it would have heard the original live perf... | |
| How much does tonearm cable affect cart loading? Moving magnet cartridges are sensitive to load capacitance, and the capacitance of the cable should be summed with the input capacitance of the phono stage or preamp to determine if the total load capacitance is within the range recommended by the... | |
| Hertz Meter Reading Device As the frequency gets lower, you'll notice the volume decreasing as well. There will be a point where the tone is no longer audible. You have just experienced the bass roll off of your system.As well as the roll-off of your ears, of course, Bob, w... | |
| Hertz Meter Reading Device It is meaningless to ask "how low it can go" without specifying some number of db that the spl has declined by, relative to the response at some reference frequency (say 1kHz).A common way of specifying bass rolloff might be something like it is d... | |
| iTunes can't find Network Storage Also, if your NAS is assigned an ip address by a dhcp server in your router or whatever (as opposed to having been manually assigned a static ip address), it could now be assigned a different address than it previously had, as a result of the new ... | |
| iTunes can't find Network Storage "102.168.1.8" should undoubtedly be "192.168.1.8"; not sure if that is a typo -- if not that is definitely part or all of your problem.Also, can Windows see the NAS (under "My Network Places" or "Windows Explorer," or whatever Vista's counterparts... | |
| How to fix my detailed, accurate but BRIGHT system TVAD:On the other hand, we can also not exclude the possibility that he is right. In the acknowledgments section of his book, Harley thanks several experts in specific fields of audio who provided technical review of his manuscript. I am going to ... | |
| Amp damping factor? Magfan,Yes, that all sounds right. As you imply by referring to instantaneous ratio, the damping effect is frequency dependent (since speaker impedance varies with frequency). By convention, though, the numerical value specified for the damping fa... | |
| Amp damping factor? Keep in mind that many amps with extremely high damping factors achieve that by means of large amounts of feedback, which results in several well-recognized negative side-effects. These include transient intermodulation distortion, which results i... | |
| Should I Bi-Wire or Use Jumpers? In principle biwiring should provide some degree of improvement in accuracy, but subjectively that may not be preferable. See the following threads, especially my posts near the end, in which I provide a technical explanation:http://forum.audiogon... |
