| How do you know what you're missing? Life music would be the best, except it depends on acoustics on the venue - from good to very bad. What about Rock? Most of concerts I attended had horrible acoustics. The best seats in Symphony Orchestra are sold only to subscription, while af... | |
| Guidance for choosing step down transformer for audio gear dannad,+10% is customary and listed in my Benchmark AHB2, but M10 specification or back panel says nothing. They don't even mention frequency. I'm sure it works at 50Hz, but no specification available.If we assume that NAD would be completely sa... | |
| Try to train them...again, or simply shoot them? Training won't do. I say shoot them. | |
| Guidance for choosing step down transformer for audio gear goldenear, standard voltage in Switzerland is 230V 50Hz (not 220V) - only 4% lower than max 240V rated for the NAD - not safe. With transformer it will operate at <50% of max rated voltage (most of Europe had 220V while UK had 240V. Now Euro... | |
| Replacing Amp Caps Dannad, I cannot see you simulation, but load and not the source should be a constant current. Because capacitor voltage is pretty constant you can just use resistor as the load. | |
| Replacing Amp Caps dannad, I would assume, that larger capacitor has larger ripple current. The thing that worries me is that, for instance, rectifier was chosen with certain peak currents in mind*. If they are deigned with certain margin, then by using lower ESR ... | |
| Replacing Amp Caps dannad, Thank you - very interesting. I wasn't expecting that. So my reservation about inductance is unfounded. I would still be a little afraid of lower ESR. If we reduce voltage ripple using larger capacitor (and lower ESR), we have to be su... | |
| Replacing Amp Caps Be careful with high capacitance values that you might not need. By getting much more capacitance you are also adding much more inductance, making sluggish power supply. Yes, you can always bypass it with lower inductance smaller caps, but then ... | |
| Replacing Amp Caps Steve, Rated voltage has to be equal or higher, but as you can guess if it is too high something has to give. It is usually size or ESR. There are many factors that would be helpful, like ESR and max ripple current. There are tons of capacitors... | |
| Dinah Washington, have you listened to her? Dinah Washington "rough around the edges" ??? The most popular and beloved black artist of 50s. Incredible talent, that died too soon. She was known for exactly the opposite to "rough" - an excellent voice control. She was highly regarded by other... | |
| Question about length of SPDIF COAX interface cable length @jjss49 I tend to overanalyze things. I'm sure nobody decided upon 1.5m based on electrical calculations, but rather on empirical experience and calculations came later to find explanation for that. | |
| Question about length of SPDIF COAX interface cable length Uberwaltz, In case of regular cable coiling doesn't matter, since cable is not a wire but the pair of them with opposite direction currents, that produce opposing magnetic flux. That would be a common mode choke, and that's how non inductive bifi... | |
| Question about length of SPDIF COAX interface cable length grm, I'm not sure if there is any formula, and case of your 8" cable shows it. What counts into calculation of transmission line effects is transition time that can vary between 5ns for dedicated transports to over 50ns for average gear. In add... | |
| Question about length of SPDIF COAX interface cable length grm, I assumed typical 25ns transition time, but perhaps it is different. Maybe your source is swinging faster, especially at smaller capacitive load (shorter cable). Whatever it is - ears are the best judge. Same goes for different 1.5m cabl... | |
| Question about length of SPDIF COAX interface cable length I tried it with .5M, 1.0M, 1.5M cables on my own DAC and prefer the 1.5M as well..I would also pick 1.5m from these choices. 8" (0.2m) shouldn't have reflections at all (not a transmission line). |
