| Shielding components from EMI/RFI... Help please Hi Bryon,I think we had concluded earlier that the ground wire connecting the PSU to the chassis was for the purpose of connecting filter capacitors between the chassis and each of the two AC input wires (hot and neutral). Therefore removing that ... | |
| Sound Quality...iPad vs iTouch I'd appreciate anyones thoughts on why the digital stream would be better out of an iPad vs an iTouch.Hi Harry,While I don't think that it is possible to predict which would be better, aside from experience (yours or others), it is certainly conce... | |
| Strage problem - power lines amps /preamp noise That is puzzling indeed. All I can think of is that there is something defective in the preamp, perhaps a capacitor or a tube, that (a)is temperature sensitive, and therefore does not occur until the unit has been operated for some time; and (b)fo... | |
| MC240 vs 8B Nicely done writeup, Jim, and I for one don't find your conclusion to be at all surprising.I wouldn't characterize Art Dudley's writeup as trashing the 8B. And while his review described a number of significant sonic issues that he perceived, many... | |
| Strage problem - power lines amps /preamp noise Could be a lot of things. Some questions:1)Are you using balanced connections between the preamp and all of the amps that you have tried?2)When the noise returns after an hour, instead of moving the preamp's AC plug to a different outlet have you ... | |
| RCA vs optical cable? Depending on many system-dependent variables, intentionally introducing what will probably be a significant impedance mismatch by using an analog interconnect to conduct a digital signal might in some cases, by happenstance, produce good results. ... | |
| what is an ideal tube amp Regarding the statements that have been made about losing half the power vs. not losing any power, if the nominally 16 ohm speaker is connected to an 8 ohm tap, in most cases the truth lies somewhere in between. It depends on the output impedance ... | |
| 2011 Mac Mini - Is SSD worth it? 04-06-12: NonoiseI tried to find a link to a thread, here, on Audiogon, where someone who's expertise is in SSDs and the like went on to state that SSDs are not any more reliable or quieter since a HD can be insulated to where noise is not a facto... | |
| 3 preamps with transformer hum, DC on the line? On the question of what an isolation transformer will and will not pass, I've got to agree with Jim here. A properly functioning transformer cannot pass the DC component of a waveform, regardless of whether that DC component is the result of a dis... | |
| Another speaker cable question? Hi Nick,After looking at the impedance curve of your speaker, I don't see cable inductance as being particularly critical. Keep in mind that the impedance presented by inductance ("inductive reactance") is directly proportional to frequency, and a... | |
| 2011 Mac Mini - Is SSD worth it? As far as I am aware it's simply a matter of people having reported in many cases that they obtained improved sonics with an SSD, with the rationale and explanations being speculative. In addition to the possibility of reduced vibration to which M... | |
| Impedance in headphones vs. speakers - confused Excellent explanations by Bombaywalla. A couple of additional points:1)Another possible reason for the recommendation by your integrated amp manufacturer to use headphones having impedances of 50 ohms or more is that while its headphone amplifier ... | |
| tonearm cable capacitance, Origin Live Illustrious Is higher capacitance necessarily desirable in a tonearm cable?Hi Lloyd,Absolutely not. Assuming that you are referring to a moving coil cartridge, the reverse is more likely to be true. See the post by JCarr here.If you are referring to a moving ... | |
| Dielectrics and such...?? 04-05-12: 2chnlbenHow then would you suggest I utilize my Kimber wire. I have plenty of it to work with. The 4tc does not provide a lot of copper (gauge). I want to increase the amount of copper (gauge) and thus my desire to use four sets per spea... | |
| Dielectrics and such...?? 04-05-12: 2chnlbenI want to use each "braided pair" (one complete run of the 4tc) per speaker terminal (2 runs - one to each of the top/bottom positives, and 2 runs - one to each of the top/bottom negatives). Hi Ben,Thanks very much for the nice w... |
