| any decent 12Vdc power supplies that can be used as a 12V trigger? Your amp will work, even without anything connected to trigger input. Yes, amp turns ON with the presence of +12V, but this voltage is already there (pulled-up internally to 12V). Try shorting this input to GND - it will turn your amp OFF while ... | |
| Cheap crimp connection vs. Solder Soldering doesn't remove/replace crimped connection. Yes, it adds another layer, but in parallel - lowering overall resistance. Soldering makes overall connection stronger. | |
| any decent 12Vdc power supplies that can be used as a 12V trigger? I believe that your integrated should work without anything connected - it pulls up trigger input internally. In order to shut amp down you need to short this input to GND (or at least to drop voltage below 5V). likely you don't need any externa... | |
| Cheap crimp connection vs. Solder Why to replace crimp with solder? Crimp creates oxygen free connection and the only drawback might be how strong it is. I crimped and then soldered, applying heat to wire first (to keep compression). I'm not sure that silver solder I used makes... | |
| Disagreements and Conflicts between Audiophiles have we lost our brotherhood and maturity? I'm guilty myself for participating in pretty bad discussions, but I'm learning to behave. Late Almarg gave be an example how to behave that I will try to follow. | |
| any decent 12Vdc power supplies that can be used as a 12V trigger? Are you asking about +12V trigger for power supply sequencing? If so, devices have their own internal pull-up to 12V and are being shut down by pulling it down to GND. I had one power amp that required more current to pull to GND than pre was ab... | |
| Do You Unplug Equipment During Thunderstorms? I have Whole House protection at the panel with non-sacrificial secondary protection (Furman Elite-20 PFI) at the system (audio, TV). Normally I don't unplug during thunderstorm unless is starts hitting very close. There is no protection for dire... | |
| Repair for speaker cabinet Have you had work done by piano repair shop? No, but I have black glossy speakers, similar to Wilson Puppy, and the piano repair shop would be the first place for me to check. Trying to repair myself damaged surface with black epoxy could get ... | |

| Vinyl sounds better (shots fired) With computer server you could use parametric equalizer to improve sound in the room and to buy downloads at about 1/2 price of vinyl. Perhaps eliminating TT and Phono Preamp allows to get better amp or speakers? CDP has to stay anyway since vin... | |
| 75 Ohm BNC cable @jasonbourne71 Reflection coming from the end of the cable (if any) can deform original edge affecting timing. For 1.5m cable reflection from the end of the cable comes back in 15ns (5ns/m x 1.5m x 2). Even the very beginning of transition (... | |
| 75 Ohm BNC cable Rule of thumb says that cable becomes transmission line (reflections) when signal propagation one way is longer than 1/8 of signal transition. Since typical transition is in order of 25ns it is about 3ns propagation. Signal travels about (dielec... | |
| Would I be wasting my money to get a turntable? What happens when your PWM’s oscillator signal frequency is not high enough? This frequency, likely >0.5MHz limits amp's bandwidth. My older Icepower was limited to 60kHz, resulting in 20deg phase delay at 20kHz. It can affect summing of t... | |
| Would I be wasting my money to get a turntable? What do you call the conversion of an analogue signal to a PWM/PDM or ΔΣ modulation and its subsequent filtering to recover an amplified analogue signal? Because if that’s not digital, then CD is not digital and streaming is not digital either. H... | |
| Silver spades Total spade resembles roughly AWG10 and distance of 1/2". Copper 10AWG resistivity is about 0.001ohm per foot. 1/2" spade would have resistance of 0.000042 ohm. Silver spade would be 0.00004 ohm, while aluminum spade would be 0.00007 ohm. Such... |
