| the paradox of accurate speakers Even if there was such a thing as an absolutely accurate speaker, it would be rendered less than accurate when placed in a given room. That's because the room is also a speaker enclosure. Just like a speaker cabinet, the room imparts standing wave... | |
| Tube amps and power consumption Generally, Class A and Class A/B tube amps will have an efficency in the area of 25 percent. If your amp consumes 300 watts total, then the power rating is around 75 watts per channel. A solid state Class A is generally less efficient (about 20 pe... | |
| Do amplifiers deteriorate if not used? Yes. Some electrolytic capacitors may be shorted, even if the amp is idle for as little as six months, depending how old they are. What happens is that a thin layer of aluminum oxide insulating the foil deteriorates and the cap shorts out. This in... | |
| 4 ohms and 8 ohms Forget the ratings for a second. An amplifier presents a voltage to the speaker. A speaker presents a resistance (ohms) to the amplifier. This pairing causes a current to flow from the amplifier to the speaker. The current is directly dependent on... | |
| Polarity Questions.. In my view, it is one more thing to obsess over. I think it's futile to sit there and attempt to identify the best polarity setting for every single track you will ever play.I have noticed differences in polarity - only by accident. Once I was lis... | |
| freq range, 50hz-20khz at + -3db please explain It's not as simple as a "loudness value" nor is it a relative volume level comparison between frequencies.A speaker attempts to reproduce what is on the recording as accuarately as possible. Since we can hear in the range of 20 to 20kHz, most spea... | |
| ground connection on dedicated line? All electrical codes that I know of specifically state that every electrical service must be grounded at the source (utility) transformer and that all equipment grounds must terminate at that point. In other words, there can only be one point that... | |
| Is 10/3 OK instead of 10/2 wire The reason he probably used 10/3 is because he had it on his truck. It's common stock; 10/2 is an oddball order. Not a problem.An isolated ground receptacle is used only when you have metal clad feeders (aka BX or MC) connected to metal boxes. The... | |
| Dedicated Line The bars are connected for a reason. Leave them alone. To answer your questions:1. If you seperate the bars, then each and every circuit breaker in the panel might not trip properly on fault. Self-explanatory as to the danger.2. No. Only one groun... | |
| Food for thought for all us audiophiles So the point is we are just fooling ourselves when we spend a lot of money on audio gear. Or maybe it's that we are wasting money. Well what business is it of anyone else how one spends their own money? What should we buy instead? Who decides what... | |
| Can speaker cables be too thick? Look inside some expensive speakers. The wiring from the terminals through the drivers are as thin as hair compared to the garden hoses some use on the other side. Why, then, after countless hours and dollars on R&D with respect to cabinet con... | |
| The Irrational But Efficacious CD Tweak This post sounds eerily close to a Machina Dynamica testimonial. | |
| CD player making strange noises The motor noise thru the speakers is probably a defective or loose noise filter (capacitor) across the motor terminals. The pops and crackles are probably dirty/oxidized/loose connections here, there or everywhere. I also agree with Edle - the pow... | |
| my take on blind tests DBT's are irrelevant, IMO. Everyone who intimately knows their system will most likely be able to detect a change (or lack of one) with a new component inserted. But to sit there and try to differentiate between cables, amps, rubber feet, whatever... | |
| Most Influential American Musician of All Time? W.C. Handy. First to use the 12-bar blues which underlies most of the music genres. Chuck Berry turned it into rock and roll and the rest is history from there. |
