| Can I use 24 gauge speaker cable? 100Hz is too strong, in most cases, and small resistance in series helps to reduce it, since there is also impedance dip at this frequency. Nobody talks about kiloohms - that’s not a valid argument.All I’m saying thin speaker wire might change sou... | |
| Can I use 24 gauge speaker cable? sjeesjie, AFAIK biwiring can have effect on the sound by eliminating skin effect (I don’t believe it’s audible) and by reducing back EMF injection into other xover section by separating them by impedance of the driver+wire / impedance of the amp o... | |
| Can I use 24 gauge speaker cable? Dynamic speakers, in general, have their lowest impedance at low frequencies and small gauge wire will result in reduced bass.Not necessarily. Many speakers have impedance dip around 100Hz - bass reflex hump. Taming it might be a good thing. I too... | |
| Can I use 24 gauge speaker cable? 1. Resistance: About 0.5 ohm in series with the speaker for 10’ cable. It will affect the sound with changing speaker impedance, but you might like it.2. Damping: For membrane damping 0.5 ohm doesn’t make much difference since there is already at ... | |
| Theoretical Pre Amp Question Benchmark's recommends highest gain settings at pre and the lowest at the power amp. They provide option of 22dBu (9.8VAC) input in AHB2 power amp. I understand that they want to move gain from noisy environment (power amp) to quieter environmen... | |
| A long harsh digital trip - final meter? USB cable shouldn't matter with the data delivery, but might inject electrical noise as any other cable connected, especially connected to noisy computer on the other side. Selecting cable with good shielding, to avoid ambient electrical noise pi... | |
| Surge Suppressor Basics I use furman Elite 20 PFI, that uses similar scheme. Big inductor in series followed by big capacitor (parallel). They claim it can provide 55A peak current. Most of linear power supplies draw current in short pulses of big amplitude and this arra... | |

| 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 ... |
