| Math + Logic + Science = something completely mad... bruce19 I replaced banana plugs with spades by crimping them first and then soldering with WBT 4% silver solder. I applied heat to end of the wire first to prevent spade expansion and loosing oxygen free connection. That way it's oxygen free an... | |
| Math + Logic + Science = something completely mad... Negative feedback increases the bandwidth w.r.t. the definition of bandwidth as the -3db point. However, it does not increase gain at that frequency. We are both going off memory but I am almost certain an amplifier in 1969 didn’t have the IMD num... | |
| Math + Logic + Science = something completely mad... I am wrong about 100x higher gain, since only fraction is fed back to the summing junction, but it is in the same level as nominal amplifier’s input. It won’t be as sensitive because of lower impedance, but will still inject noise picked up by lon... | |
| Math + Logic + Science = something completely mad... Those amplifiers had lots of feedback, but very poor gain bandwidth product. That was why they had bad distortion products, and why they had poor output impedance at high frequencies. They had excellent THD and IMD. Designers were sure they hav... | |
| Math + Logic + Science = something completely mad... dletch2 Let me get to some technical points first. I brought example of amplifiers in 70s to show that there is always possibility of something we don't know yet. Designers then believed that NFB is a panacea for everything since it reduces TH... | |
| Math + Logic + Science = something completely mad... dletch2, I'm trying to describe what I hear, while you're saying I have to be mistaken because something like that does not exist. That is my whole point - you're starting from the wrong side, trying to disprove what can easily be heard. You als... | |
| Math + Logic + Science = something completely mad... dletch2, I remember long time ago I had inexpensive cable from Best Buy. I believe it was Monster Cable brand. It consisted of two parallel runs of very thick stranded wire in thick clear plastic (most likely PVC) insulation. It was suppressing hi... | |
| Math + Logic + Science = something completely mad... Jitter for one is bidirectional. It causes harmonic distortion and uncorrelated noise. I'm not sure what "bidirectional" means. Do you mean "sidebands"? Jitter does not cause harmonic distortion and that's the reason why is still audible in spi... | |

| Why Does All Jazz Sound The Same? @snackeyp What you are hearing is related to musical training. Classically trained musicians know where the right notes are and get them on the first try, while Jazz musicians go by trial and error. Jazz bass or guitar player "walks" all over the ... | |
| What happens with Hyperion Sound Design imith314 Thank you. I noticed it. I asked them about ferrofluid in midrange drivers and got no response. I asked them again today. Hopefully they will respond and provide support. Fantastic product, but poor marketing and dealer base. Pitty. | |
| Bluesound Vault & Original CDs RIAA says you can play from computer/storage, as long as you keep physical copy (CD). That way artists royalties are paid. You can even legally copy your friend's CD as long as you use "Audio CD-R" (that pays royalties). AFAIK RIAA doesn't both... | |

| high sensitivity + low impedance vs. low sensitivity + high impedance Pretty much the same current is required to drive both speakers to the same loudness (speaker Y will be louder by about 1.5dB - not detectable). | |
| Connecting a streamer via an Ethernet cable I use WiFi for practical reasons (cannot run cable across the room). It might be even a better way of delivery since anything physically connected injects some electrical noise. We can argue that WiFi introduces electrical noise itself, but it i... |
