| RMS Power? From Wikipedia "Audio Power"As described above, the term average power refers to the average value of the instantaneous power waveform over time. As this is typically derived from the root mean square (RMS) of the sine wave voltage,[6] it is often... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Ramtubes, I explained exactly what I agreed with by quoting your statement - read again.Why are you bringing emitter resistors again, yes we know that they exist. I'm not sure why you're asking me what Benchmark voltage regulation is. Perhaps y... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Once an amp clips feedback cannot make up for these losses. I agree, but amp that doubles power exactly has to have adequate power supply AND deep negative feedback. Exact doubling implies perfect regulation (ideal voltage source), that is not po... | |
| A very good ENGINEERING explanation of why analog can not be as good as digital.. Why not bring other issues related to digital, like aliasing or jitter? Also Nyquist/Shannon theorem applies to continuous waves only. Yes, you can accurately recover the sinewave with only two samples per period, but to do so you need a lot of pe... | |
| Help with choosing music server Fast, I had the same problem of dropouts until I changed to 5GHz band (bought dual band router). 2.4GHz has only 3 channels (since each of 12 channels is more than 3 channels wide). 5GHz, in addition of higher number of channels, has advantage o... | |
| Damping Factor The highest effective DF (for the purpose of damping motion of the membrane) is 1.5It is because DF comes from dividing nominal speaker’s impedance by total impedance in the circuit. It is important to understand how damping of membrane works. Whe... | |
| Could I be a Retail Wretch? jetter, sure all is in the intentions, but I also feel that demoing equipment is a part of manufacturer's service thru the dealer in order to promote their product. I cannot imagine car maker authorizing any dealership that doesn't provide test d... | |
| Rectifier Tubes At the top of rectified full wave sinewave current changes direction but rectifier is too slow to respond and keeps conducting in opposite direction for a moment then snaps back to zero current. Fast snapping back creates very narrow negative curr... | |
| Yter cables direction Why would you think it is important if manufacturer doesn't (doesn't mark it)? I could not find anything about directionality on their website. | |
| Help with choosing music server You rip a CD and it pretty much gets organized the same way iTunes does.I don't like amount of scrolling you have to do to get to particular album in Itunes, but if you create "smart playlists" for each genre (like "genre IS Jazz") then Itunes dis... | |
| Could I be a Retail Wretch? Happy to pay for test drive? Nobody would even accept money for that. It is assumed a cost of doing business and I wonder why Audio has to be different? (some dealers already charge for audition). | |
| Difference between " AES " and " RMS " power of a driver. It is not mutually exclusive. I appreciate technically correct terms AND I know what advertising, hi-fi magazines, audio reviews etc. mean. | |
| Could I be a Retail Wretch? Viridian, It is hard to tell dealer that I will buy or not buy the car if I never drove it. Test drive and presentation is treated as a service on behalf of the car maker. I just bought a car few months ago - 2019 brand new design. This car will n... | |
| Could I be a Retail Wretch? Would yo be HAPPY to pay for test drive of the car? | |
| Could I be a Retail Wretch? Class dealer? Audio dealers recently charge for audition!!! I don't see a reason why anybody wouldn't give dealer a chance to match the price. Saying so is a strawman argument. |
