| to ground or not to ground There are two types of grounding: one is the signal zero voltage path which is required for all signals to pass thru the equipment, and the other is the earth safety bonding which is the third prong on the plug/receptacle. Both serve two different... | |
| Build my own speakers? I don't know of any "new top of the line" speakers that use readily available, out of the catalog drivers throughout. The $20k Magico Mini, eg, uses the revelator but the other driver is custom made. Top speaker manufacturers custom engineer their... | |
| For best CD playback is SACD needed? If you cannot hear much of a difference, then I would ask what are you listening through? Looking at your system link, my guess is that you are basing your conclusions from a $200 Onkyo receiver and MB quart speakers. Sorry to be blunt but I don't... | |
| Why Do Audio Engineers Use Different Speakers? Another way of asking your question is: Why aren't powered speakers popular with audiophiles? Simple, they'd be "stuck" with one amplifier. The thing that drives this hobby (and keeps people employed) is the constant changing, upgrading and experi... | |
| compliments What make is the tube? You should name names... nothing gets a mfr moving to keep their good name like the prospect of a little negative publicity. Tubes can loose their vacuum due to manufacture defects (maybe a bad batch that others bought) so i... | |
| Stereophile Review of Quatro Wood I think there's a point being missed here. From what I've read, the purpose of the speaker was to make the line more appealing at the request of dealers, not to offer up a different or lateral product to die-hard Vandy fans. As such, prospective b... | |
| New dedicated lines Again, it's more involved than just which leg of the panel you place the breakers on. With single phase power, each leg provides 120 volts referenced to ground. There are two of these legs and the start of getting good power to your gear is to kee... | |
| New dedicated lines Use different phases for each of the monoblock circuits and maintain the same length of feeder. If you keep all your equipment on the same leg you'll be inviting a ground loop hum, especially with four circuts. Factors which induce ground loops: m... | |
| 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... |
