| Hard to believe all the crap that flows thru an ethernet cable What addl isolation do u recommend?I don't know, but $1300 seems to be excessive. | |
| CD vs FLAC stored on flash drive vs streaming It appears that these pictures show physical burn to gold or aluminum layer. CD-Rs have photosensitive dye - there is no physical burning. CD-Rs can be written at speeds up to 52x. Reading at 1x should be fine, otherwise we would have huge prob... | |
| Hard to believe all the crap that flows thru an ethernet cable AFAIK galvanic isolation is built into Ethernet standard (transformer or optical), but any additional isolation might help. It would be wise to try before spending money. DAC designers would likely use transformers, since they eliminate DC and s... | |
| CD vs FLAC stored on flash drive vs streaming Most of CDPs operate in real time. For short scratches along the track (shorter than 4mm) they supply data from error correction. For 4-8mm they interpolate lost data and above that they lose data (gaps). Ripping is not real time process. Comp... | |
| Power Conditioner vs A/C cables I decided I need power conditioner with filtering and strong overvoltage protection anyway. I bought Furman Elite 20PFi and placed it on the shelf below DAC and amp. I concluded, that if power cables have effect on sound, it will be proportional... | |

| 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... | |
