| Room Treatment A "panel" is a generic term. Panels can be absorbers, diffusors or a combination. There are also bass traps which are a type of absorber that is especially effective in the bass region. GIK makes some panels which are a combination with absor... | |
| confused about 20 amp power cables Check the fuse rating on the back of your amp. It’s probably a lot less than 20A. :) I don’t have access to the manual but I saw an image which specified 1500W on the back. This should be around 12 Amps. A 15A circuit is generally rated to 1800W, ... | |
| Why do tube amps often subjectively sound more powerful than SS ? Nelson Pass wrote an interesting paper on this and I think this is it. It doesn't directly say tube amps but rather amplifiers with high impedance. Worth a read. Contrary to popular opinion, I greatly appreciate how much Nelson Pass does for t... | |
| AC Power OP, Glad it's working out as well as it did!! Yes, your observations of daily voltage variances are exactly why I recommend voltage regulation over a dedicated circuit OR balanced conditioner. Installing a 10 gauge, 30 Amp circuit is just not g... | |
| Speaker or amplifer If your room acoustics are so-so but you listened to a pair of speakers in a dealer in an ideal acoustic environment, maybe you need to think about room treatment? | |
| Insane ground loop; anybody wanna try? Sorry, coax only matters when it's coming from outside, like a Cable TV box, or satellite dish. Coax from your streamer or DAC however is not a high risk of causing a ground loop. | |
| Insane ground loop; anybody wanna try? You didn’t mention it, but just in case, make sure to remove any coaxial cables, including any you might have plugged into the surge protector. If an amp hums all by itself you may have DC on the line. Try moving the amp to another room or even a... | |
| AC Power The "dirt" in AC is higher frequencies than 60 Hz. True, which makes series mode protection so good. They are effectively low pass filters which start working around 3kHz. That's a lot lower than EMI/RFI filters which usually start around 100... | |
| AC Power In looking for other voltage reglating "conditioners" I looked at the Furman P-2400 and the specs say that it regulates voltage to 120V +/- 5V. 5 volts is not real regulation in my opinion. is the voltage regulation realy that bad? Yes, it ... | |
| Maybe critical listening skills are bad? My argument about precise imaging was about how in person listening I don’t get the same imaging illusion. If I close my eyes I can’t place instruments nearly as well as I demand from my stereo. I argue that we seek out imaging that is too precis... | |
| AC Power @jea48 - The approach Furman takes, which appears to be to switch as close to the zero Volt crossing of the AC waveform is pretty thoughtful and not common among all regulators out there. IMHO it’s a very cost effective design overall. Interest... | |
| Power supply to modem make a difference? The issue IMHO isn’t noise via network but noise via the AC line, and potential for surges coming in from the cable line unless it’s fiber already. For power supply issues I use iFi supplies like these. For surges I have one of these outside an... | |
| Maybe critical listening skills are bad? The interesting finding in such research is that not all physical qualities to which experts may be attuned correlate with liking. In the end, product developers need only attend on those physical qualities that are associated with what the targe... | |
| AC Power Also, it's my experience that autotransformers like used in voltage regulators don't have the mass inrush current that the dual winding transformers have which are used in isolators. I could be wrong, but this is my memory. When I turn my 1800VA... | |
| Has anyone tried these SnugPlugs? Dear lord, no. If your plugs are that loose they need to be replaced. The NEC now requires tamper resistant outlets in most outlets in the home, so not even sure a snug plug would work in any outlet that’s compliant. A decent "commercial/reside... |
