| The Clever Little Sharp Hell, I've seen posts here that debated things like the effect of receptacle wall plate material. So why is THIS causing sacrilege? Because it defies common sense or knowledge? My common sense once told me that an "EMF sponge" is nonsense. Yet I s... | |
| Filter capacity in 2A3 amps In a 2A3 amp, the mains voltage is stepped up to a range of 250 to 350 volts, which means a load current in the milliamps to provide the output power of about 2 to 5 watts. In solid state amps, the voltage is stepped down to about 30 volts and the... | |
| condo owners, how do you appease the neighbors? Unfortunatley, there is little recourse on your part. Your are considered the "neighbor from hell" to the downstairs tenant. He has options such as initiating a condo board hearing or a noise abate lawsuit. Both can make your life miserable. Apart... | |
| Why outlet makers warn against aluminum wires? It's more than just oxidation and "cya". Aluminum and copper wire connections can cause arcing which can lead to fire; they need a special crimped connector, which completely encases the interface, to safely join them. The manufacturers of outlets... | |
| hum from nearby high-tension wires? Another possibility is the university complex itself is the source. There are probably large motors for air condioning and elevators, some of which may be variable frequency drive, that puts noise in the power grid. Another possibility is that the... | |
| Tube Break-In sound character change You replaced 2A3's with 300B's??? I dont' think break-in is at issue here, but compatibility. | |
| THE POINT SYSTEM OF WAF. You earn enough money in a month to buy any tube amp or big gaudy speakers - retail (+1,000,000) | |
| CLASS A AMPLIFIERS Generally, they are not more powerful. Class A designs are extemely inefficient because it requires that a lot of heat be dissipated to maintain stability, robbing power to drive speakers. For technical as well as practical reasons, this limits th... | |
| Efficient speakers v. less efficient speakers Short answer: no. You cannot generalize that higher sensitivity speakers paired with a low powered amplifier is equivalent to a high powered amp and low sensitivity speakers at a given sound pressure level. It depends on the quality of the amps an... | |
| When is unequal, equal? A difference of 8 feet will not make an audible difference. This is easily shown with the math, but without the boring details:Assuming the speakers have a 90 dB/2.83V-m sensitivity at an 8-ohm nominal impedance (1 watt) and that the speaker cable... | |
| Dedicated power,long power cords - waste of time? My 2 cents says go with Wiremold. It's the safest (i.e., legal) and most cost effective way to solve problems such as yours where behind the wall wiring is impractical. | |
| Speaker cable gauge and amplifier power One thing that I found interesting is the wire guage used INSIDE speakers from the terminals to the drivers. We hook up our 8-ga hoses to speakers that use 16 or even 18-ga internally. This renders anything larger before it moot. So unless you nee... | |
| Amp Ground Plug - Safe to Remove? The purpose of the ground plug is to return a fault current, such as a live wire touching the equipment chassis within, back to the panel. This does two things: it reduces the chance of shock or worse, and it enables the circuit breaker to trip - ... | |
| can a power regen. eliminate ground loop hum etc? First check to make sure the incoming cable service is properly grounded to the electrical ground (water pipe or ground rod) of your house's power service. Call the cable company or an electrician if you're not sure how or what you need to look fo... | |
| Shouldn't amp reviews employ multiple speakers? I would agree somewhat. Using one set of speakers that you are familiar with will enable you to discern differences in amplifiers more readily. Especially if the speakers have a quality of being revealing - such as the Thiels - and are considered ... |
