| Caps for crossover upgrade for Opera Grand Callas Loudspeakers Hey @dgarretson What uF were the Clarity you bypassed?My experience has been that below 4-5uF I can't hear any difference in bypassing them. I also used 0.047 Duelund pure silver caps on the 10 uF caps I have. No difference for me. I needed at lea... | |
| Caps for crossover upgrade for Opera Grand Callas Loudspeakers So you have good experience with Clarity Cap CMR bypassed by a copper caps. Which one? I used the Audyn TruCopper models. In what do you prefer CMR Clarity Cap over Duelund and Jupiter? Cost and size! But if I could afford Jupiter copper foils I... | |
| OT: Using electrostatic motors for a watch movement Damn, I don't know why I always call the Seiko movement a "Swing Drive" instead of a "Spring Drive." :D E | |
| The Science of Cables I agree that cables are super easy to measure in terms of R, C and L. I think that what's not well understood is their effect on the final output. I've heard speaker cables behave in such a way that makes me believe amps and speakers are more susc... | |
| Site is hacked I'm having the same issue on Android. I get redirected to a fake Youtube site. | |
| Recommendatios? Class D has improved quite a bit over the last 10 years. Consider a newer integrated in either Class D or linear ranges. I'd ask about bass traps, and room modes. It could be you need not anything better, just different. I don't know of speakers ... | |
| Caps for crossover upgrade for Opera Grand Callas Loudspeakers Actually, given the costs involved here, before you begin, you should probably invest in a Dayton DATS V2. Measure the impedance of the entire speaker, and it will let you measure the ESR and DCR of any components you pull out. Then you can use it... | |
| Caps for crossover upgrade for Opera Grand Callas Loudspeakers It would be interesting to see the impedance curve, but the 100uF shunt cap on the woofer is interesting. They usually need 0.5 Ohms to 2 Ohms to prevent an impedance issue in the next driver up. Don't replace it willy-nilly. Measure the ESR and a... | |
| Caps for crossover upgrade for Opera Grand Callas Loudspeakers Those caps are top notch for their type. Magico uses them or very similar, and .... I don't like them! :) I far prefer Clarity CMR + 0.1uF Copper foil bypass caps. as giving a much more natural and relaxed presentation. If money is no object, size... | |
| OT: Using electrostatic motors for a watch movement Indeed! Comparable to the Seiko Swing Drive. | |
| Bias adjustment on solid state amplifiers Because it's a set once and forget forever issue with SS amps. Also, you aren't as much setting bias as DC offset. | |
| Fundamental importance of power management I've put together a blog post on my thoughts here:https://inatinear.blogspot.com/2019/04/power-management-for-frugal-audiophiles.html | |
| Recommendatios? What are your room acoustics?? | |
| New Joseph Audio Pulsar Graphene 2 BTW, I am not of the idea that the only way to value a speaker is by driver costs. Manufacturer reputation, and relative performance to other products in the same price range are important, as is attention to part quality in the crossover, cabinet... | |
| Fundamental importance of power management A lot of my posts are about basic guidelines to power management. Keep your wall warts out of your analog zone. Use inexpensive shielded cable. Use a coaxial ground isolator for incoming cable TV/antennas. But I do want to say that at a certain po... |
