| 15 amp circuit VS. 20 amp Circuit That’s a lot of gear. Honestly if you weren’t going to run them at maximum output all the time you are probably fine so long as you don’t try to turn them all on at once. The better your wiring to your stereo, the more likely you are to dim the h... | |
| Stereophile spec measurement baffling(pun?) At best it can tell you how much air the speaker can move. Audiophiles rely on this spec way too much IMHO, especially when deciding whether or not to add a subwoofer and how to configure one. The room makes liars out of all of the anechoic/quasi-... | |
| The Low Volume Loudness Dilemma The main reason tone controls were considered bad, IMHO was they were often poorly implemented compared to the rest of the unit. Some had excellent tone and loudness circuits while others simply did not. The otherwise excellent Parasound P7 was ... | |
| Processor sound comparison- Anthem avm90 vs NAD M17 V2i Skip the Anthem, for two reasons. It doesn’t handle 2 channel surround correctly and the room correction isn’t all that. It doesn’t do a great job of integrating the loudspeakers and doesn’t allow you to manually adjust either. The latter is only ... | |
| Isolation transformer question IMO a regulator can do much more for you than a simple isolator, but the isolator can eliminate DC on the line, which is kind of rare, increase filtering due to increased inductance and make the incoming AC immune to certain types of EMI/RFI noise... | |
| External Linear PSU for Router - Voltage/Amps? I should have added: There was a case, the only one I know of, for a Chord portable DAC, that the device relied on a low amperage to protect the charging rate of the batteries. IMHO, a bad design choice made against convention. | |
| External Linear PSU for Router - Voltage/Amps? Match the voltage, excess Amps is OK. For instance: 12V, 8 A is just fine. The reality is a lot of nominally 12V linear supplies may provide slightly elevated voltages when unloaded, so you may read say 13.8V on a multimeter. That's fine, and e... | |
| Why Preamps Thump on Turn on @atmasphere Wow that is some serious entitlement there. I’ll get to it when I get to it. I had time then, i don't right now. Sit and spin until you cool off. | |
| Find the Problem If it hardens in the same place regardless of volume it's the TT/Cartridge. If it only hardens after turning the volume control to a certain point it's more likely to be the amp. | |
| I guess I need a new multimeter. You could also have bad leads, by the way. I like Fluke but goodness they are expensive. Often on 20% off at Amazon during holidays. | |
| Audiophile grade passive impedance buffer I should add that otherwise, imhifiman is correct. An impedance buffer is the solution. You'll trade impedance for gain, but at least it should ensure a flat response. | |
| "The Art of Speaker Design" by Lynn Olson Good points all, Hilde45. When I make a speaker, always for myself, what I care least about is pulse coherence. I’m sorry I just have never ever heard a problem which this solved for me. I have heard pulse-coherent speakers with a frequency respon... | |
| Audiophile grade passive impedance buffer Question is whether your preamp's output impedance is resistive or not. If it's resistive and your amp's input is also resistive you'll at worst suffer loss of gain. If it's a tube pre with capacitor outputs chances are it's capacitive and outp... | |
| Why Preamps Thump on Turn on @atmasphere Thanks for the follow up... I'll have to go take a look when I have time, which may be a while. | |
| How do I discharge the capacitors in my PS audio P20 ? Shorting a high uF cap directly is a bad idea. You can in fact ruin an otherwise good cap. Also, worth noting the voltage rating on a cap. If it’s 50V say or less, it’s not that dangerous. If you don’t have a 10W resistor, just use a bigger Ohm ... |
