| Short coax digital cable: qed audioquest ricabl Rodman, It is system thing, as Al stated, but in your case it is possible that your transport had about 10ns transition time. Beginning of the transition resulted in reflection from the end of the cable (impedance boundary) coming 5ns later (5ns/m... | |
| Solid State Amplifier Advancements In A Decade Extremely quiet SMPS operating at MHz frequencies and utilizing zero voltage zero current switching. Such power supplies are not only extremely quiet but also have line/load regulation. You can find them in all newest Jeff Rowland amps (including ... | |
| Short coax digital cable: qed audioquest ricabl Get 1.5-2m or less than a foot. There are technical reason for that. | |
| Is it really useless Upscaling 16/44.1 music to 24 Steakster, Linear power supplies pollute more then well executed switching power supplies, that got bad reputation from crude computer applications. Well executed SMPS is extremely quiet and that's why Jeff Rowland uses them now in all amplifiers ... | |
| why do people feel the need to buy expensive cable Rja, I've read recommendation for good inexpensive hotel in Rome. When I pointed out that it was over $1k a night, hardly inexpensive, he said "it is inexpensive to me". I would rather speculate where is the point of diminishing returns. If you st... | |
| why do people feel the need to buy expensive cable You're hearing (or system) does not allow you to hear the difference, but there is no need to be defensive about it and to post on the forum in hope of finding other people who cannot hear the difference to make you feel better. | |
| Hybrid SACDs or CDs for Redbook Playback I've read some Stereophile reviews of early SACD players. SACD sound was fantastic while rebook was not so good. Perhaps player is optimized for SACD playback. Processing for SACD and CD is completely different (different DACs). | |
| Re-capping A 15 Year Old Solid State Amp AFAIK only electrolytic caps and possibly switches if you have problems with them. Everything else should last your lifetime. Old dry caps have high ESR (Equivalent Series Resistance) increasing output impedance of the amp. It will take away some ... | |
| Suggested PC laptop models for computer audio Knownothing, Placing different peripherals on the same USB bus affect timinig. Since timing is removed in asynchronous USB scheme it should not make any difference. | |
| Suggested PC laptop models for computer audio Knownothing, In asynchronous USB computer downloads "frames" of data every 1ms into DAC's buffer. DAC sends back buffer under/overflow signal to reduce or increase size of next frame. That way no data is lost. Next, DAC takes words from the buffer... | |
| Suggested PC laptop models for computer audio Are you going to use USB? If so, then speed of computer, type of hard drive, amount of memory etc. are unimportant. It is because asynchronous USB strips timing from the signal and new timing is recreated inside of the DAC. Amount of electrical no... | |
| Tube Watts vs. Solid State Watts - Any credence? 85W vs 70W 5.7% loudness increase45W vs 40W 3.4% loudness increase | |
| Tube Watts vs. Solid State Watts - Any credence? Large headroom doesn't mean poor performance. It means that amp has ability to output higher momentary peaks. Otherwise it is power limited by power supply and/or heatsinks. That's what music is - peaks, gaps and very low average power (few percen... | |
| Safety of Older Electronics Dry power supply caps have high ESR (Equivalent Series Resistance). First symptom is loss of bass tightness/dynamics. I've seen (in commercial equipment) cap that was bulging (placed next to hot transformer). | |
| Safety of Older Electronics O_holter, romm temperature is around 20degC. It is hard to tell what is lifespan of the cap since different companies put different numbers. I would assume >50 years in 20degC. Capacitor will fail only if you leave it unpowered for many years. ... |
