| Replace volume pot Marakanetz, It looks like it is not straightforward but rather some convoluted combination of Volume and Balance with addition of Phono. I wouldn't touch it with a stick. As for technicians - it is different (from designer) set of skills. Technici... | |
| Why do audiophiles shun feedback in amplifiers? Atmasphere, Now I got it. Thanks! | |
| Why do audiophiles shun feedback in amplifiers? Dracule1, Read this:http://www.stereophile.com/reference/70/index.html | |
| I'd probably lose this bet.... Atmasphere, First speaker cable I had was thick stranded Monster cable (clear insulation). I found later that it is possibly the worst type of cable because skin effect starts in copper at 20kHz at gauge 18 causing smearing but also because same s... | |
| Devices, desktop player, formats, etc BannonB, one sentence appears to be missing in my post. MAX is a free utility program for Mac that allows to rip CDs (better than I tunes) and batch-convert any format to any format.Ideal program should rip CD as data (I set MAX in that mode) forc... | |
| Why do audiophiles shun feedback in amplifiers? since IM will occur at the feedback nodes of the amplifier, resulting in a harmonic noise floor (rather than a natural hiss noise floor caused by component noise).Atmasphere, I'm not sure I understand it. IM is caused by the presence of two freque... | |
| Devices, desktop player, formats, etc BannonB, I batch converted about 250GB of ALAC files into 50GB of 128kbit VBR AAC and put it on 64GB microSD card. I use it in my Samsung Galaxy S3 phone. MAX is for Mac but there are similar programs for Windows. | |
| Why do audiophiles shun feedback in amplifiers? Can an amplifier with no or minimal negative feedback in play make a CD recording that might be irritating otherwise normally not irritating?Mapman, you basically asking if it is possible to make amplifier bad other way than NFB. I'm sure it can b... | |
| New level of ridiculousness And how do we know that if a careful and genuinely open-minded comparison was performed in a $300K system between that power strip and a variety of $500 strips, that one of those relatively inexpensive strips would not provide sonic results that a... | |
| Why do audiophiles shun feedback in amplifiers? Charles1dad, It is possible but perhaps not very common. Everything depends on definition since even single unbypassed cathode resistor is NFB. | |
| Why do audiophiles shun feedback in amplifiers? It is not only 2nd harmonic, but also Intermodulation Distortion, Bandwidth, Output Impedance - practically everything. The key to avoid TIM is to limit bandwidth at the input to one that amp had before feedback (that extended bandwidth) was appli... | |
| Audiophile Speakers with 25 yr + Longevity John, Thanks. I don't have problem now but like to take precautions for the future, before Hyperion goes bankrupt. | |
| Why do audiophiles shun feedback in amplifiers? Dracule1, feedback is a very good think if you know how to use it. It improves practically everything - reduces distortions (THD, IMD), lowers output impedance*, widens bandwidth. The only problem is that amplifier presents delay to signal. When y... | |
| Audiophile Speakers with 25 yr + Longevity John, Thank you very much. It doesn't sound that difficult. I have one spare (upper) cabinet damaged/crushed in shipping. Midrange speaker is broken into pieces (plastic frame) but I can play with it. Some details of the construction are here: htt... | |
| I'd probably lose this bet.... Let's not forget inductance of straight wire. For instance 20' (counting both ways) of gauge 14 copper speaker wire has inductance of 12.64uH equal to reactance of 1.6ohm at 20kHz. |
