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. 
Audiophile Speakers with 25 yr + Longevity
Ivan_nosnibor, My Hyperion HPS-938 speakers have 6.5" midrange with ferrofluid instead of suspension (spiderweb). Speakers are pretty new but I will face this problem in the future. Company itself, if still in business, may belly-up soon. I don't ... 
does your system "warm up" and then sound better?
Larryi, Electrolytic caps are worse with temperature. ESR increases with temperature sometimes even causing thermal runaway when capacitor heats itself by ripple current times ESR (mostly old dried-up caps). On the other hand electrolyte eats diel... 
What can I do to improve my computer?
Timlub, as Audioengr said you cannot really improve it other than improving clock (reducing jitter) on the other side of the bridge. You can run all the programs you want in parallel and it won't make a bit of a difference, since it affects only t... 
"Native" 192 vs Upsampled 192 quality?
How can you compare when your CD data is not 24 bit? Also, the fact that DAC outputs it at 192kHz is not necessarily a good thing, since D/A converter chips have higher THD at higher sample rates. For that reason Benchmark DAC1 outputs only 110kHz...
