| tube tuner drifting station Older tuners can be subject to drift as components in the local oscillator can become temperature sensitive over time (decades). It is normal for some drift to be present even in a solid state tuner. Back in the tube days, a circuit called AFC (au... | |
| Balanced or single ended phono cable to Aesthetix Io? Since the Io has a single-ended input, using a balanced interconnect will still result in a single-ended connection. The benefit of a balanced connection is that the interconnect cable will cease to have an influence on the sound of the system. It... | |
| I used to think passive preamps were superior to active preamps given right the setup, but Saying that I hate caps in the signal path, give me direct coupling any day over it, as all caps have their own sound as well.That is why we have a direct-coupled output on our preamps. Here is a little tutorial on capacitive reactance. It bears d... | |
| I used to think passive preamps were superior to active preamps given right the setup, but But if for example the source component has a coupling capacitor at its output, resulting in a substantial rise in output impedance at deep bass frequencies, or if the output impedance varies significantly in other parts of the spectrum for wha... | |
| What is the best OTL out there? There's some out there who designed and build their own OTL that uses better tubes like KT88/120/150,,300b,,VV52b,,even 211 / VT 4C can be used and they are more efficient than the ones on the market today.This statement is false- there are ... | |
| Direction of aftermarket fuses (only for believers!) ^^ Do you understand how power cords are wired? If you get it wrong, Bad Things happen! BTW, the effects of a power cord are much easier to measure than that of fuses. I've seen a power cord rob an amplifier of about 1/3 of its total output power! | |
| XLR-Balanced Hybrid Hi-End Cable The whole point of the balanced line system is to eliminate cable artifact, and to that end sliver and gold wire should not make a difference! However, the balanced line system is a standard and if the standard is not supported by the equipment in... | |
| Speakers for Rock - up to 1kusd I have Quad 57's for Baroque, but they are unsuitable for AC/DC at realistic SPL. Of course a speaker SHOULD be able to play all musics, just as it SHOULD be 100% transparent and uncolored.Quad 57s do great on rock within their volume limitation... | |
| Determining current flow to install "audiophile" fuses. Tbg you're right, there are numerous observable phenomenon yet to be explained by our current knowledge of physics. This is true, but if you've not tried to correlate that voltage drop across the fuse and its holder, you don't know if a simple ex... | |
| Determining current flow to install "audiophile" fuses. Uh, problem is its not his experience,. Its just the old ivory tower academic type thing in action. No- its the willingness to acknowledge that people hear something (the 'ivory tower' type would have written it off as expectation bias or swamp ... | |
| Speakers for Rock - up to 1kusd The idea that there are certain speakers that are good for rock is throughout this thread.This is one of the biggest myths in the audio world! There is no design criteria that can be applied in such a way that a speaker can somehow be better at ro... | |
| Neg feedback switch It decreases amplifier gain to bring more dynamic headroom. This statement is false. 'Dynamic headroom' is a function of the class of operation (class A, class AB, etc.) and is unaffected by feedback.The amplifier gain is used to reduce the 'outp... | |
| Direction of aftermarket fuses (only for believers!) ^^ Arcing is often audible with audio equipment. An arcing power switch can make quite a racket!If you have arcing in an older house wiring system, failure of the arcing component (wall socket or the like) is eminent. It can also be a fire hazard.... | |
| Direction of aftermarket fuses (only for believers!) ^^ You won't have arcing- that would be audible! A small amount of arcing has a way of turning into a lot of it in a short period of time...Its easy to measure the voltage drop on almost any fuse in series with the AC line. There has to be one- as... | |
| Direction of aftermarket fuses (only for believers!) I hate to judge before all the facts are in but it appears your entire argument hinges on that statement, yet it is strictly hypothetical and specious. Not at all. I used the word 'might' as with some fuseholders and fuses, the voltage drop stay... |
