| What seperates "hi-fi" from "mid-fi" in cdp's? It's the same thing that seperates every other component from great to not-so-great: the power supply and output stages. The better cdp's are usually more expensive because they use premium parts for power supply, filter caps, voltage and current ... | |
| Paper Cones in HiFi? Not true at all. "Paper" tends to denote taking the cheap way out but is in fact a complicated mess of fibers, polymers, resins etc., engineered for light weight (has to react quickly), high rigidity (prevents deformation) and longevity. Paper's b... | |
| OT home wiring What you describe is not strange at all. In fact, it's common practice to wire the neutral and ground wires to the same bar. Take a look at panels with romex wiring - the greens and whites terminate on the same bar in most cases. The reason is tha... | |
| I have dedicated lines, but why is this happening? Two things you can check:The central ac unit may have a problem such as a faulty compressor (overheats?), pull-in contacts, loose wiring on the motor, loose wiring in the circuit (wire nuts, j-boxes, etc), loose fan belt on the blower, or a bad lo... | |
| Could the transformer be eliminated? The big problem is the surface area and the thickness of the ESL drivers - the bigger they are, the higher the voltage. A typical ESL has voltages in the thousands. This presents the problem of having to supply a very very low amperage; even the c... | |
| Hyperbole Watchdog Forum I agree. It will lift a haze layer from these forums presenting a clearer window into our thoughts. | |
| Isolation/coupling: basics? Take a high powered telescope. Look through it first on a tripod and then while holding it in your (trembling) hands - that's basically analogous to what vibrations do to an electronic signal. | |
| Will dedicated power lines eliminate ground loops The short answer is: not necessarily. Try to minimize the number of dedicated circuits. Ground loop hum probability increases with each grounded power cord you plug into different outlets on different circuits. Sounds counter-intuitive, but one ci... | |
| Is pure class A ss the equal to tubes? I have both: a pair of Class A monoblocks and a pair of Class A 2A3 based SET monoblocks. My impression of which is "best" depends on what I'm listening to and what kind of presentation I'm looking for in enjoying music - so all theories aside...A... | |
| Best measurment for Amp driving force W or uF Don't know what you mean by "best"... power output is what drives a speaker and is a function of the output RMS current and speaker impedance. Power supply filter caps are sized to keep enough reserve for low impedance, high power draw (transients... | |
| How does power cord affect a digital frontend? The power wiring in the wall will usually have harmonics of the 60 hz from radio signals, motor back-feed, fluorescent ballasts (which add current to the neutral), and other electric fields from power users on the same grid (elevator motors and ma... | |
| Transformers: Auto- vs. Isolating An auto transformer has the primary and secondary windings electrically joined and the isolation transformer has the primary and secondary windings...isolated.The AT will transmit electrical noise while the IT will not (as much). A shielded isolat... | |
| Vocabulary question To me it means how quickly the output signal follows a changing input signal (which is the definition of slew rate). The "faster" the output rise means (generally) that transients and silences are more accurately depicted. The biggest impact, IMO,... | |
| Tube Discussion Microphonics? Tube microphonics, generally, degrade soundstage imaging and detail. As to an "identifying" sound, tubes do not have a sonic character - the sound is a product of its environment (circuitry). Bias, gain, plate voltages, feedback loops, etc., will ... | |
| Audio Diversity - What is it? I disagree with the premise that two people hear the SAME thing. With anything. Put a musician playing live in a room and then ask people to listen to a recording of that session to name the system that accurately reproduces what they've heard liv... |
