| 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... | |
| Solid state design options... I usually take a peek at the slew rate. To me it says something about how careful the amp design is; if the amp sounds good to boot, then somebody did his homework. Higher is better but if the topology is sloppy, a high SR can mean instablity, dis... | |
| Instead 6GH8A will be possible ECF-82/6U8A They are very similar but not identical and the amps will more than likely sound different - but should work with no problem (no guarantees here). The 6GH8A's were not the kit "originals", the 7199's were; but because they became scarce the socket... | |
| How do they MIC a symphony? Another way is that the orchestra is spaced further apart on the stage during a recording session (the SFO at Davies Hall does this) in order to provide a wide soundstage and the illusion of correct instrument placement, which is purported to be d... | |
| Diagonal setup of system... You may want to search through the Stereophile archives. One reviewer (can't remember who) swore by this setup. | |
| Which cables go with what????? "Neutral" to the ear of an audio equipment designer, or anyone else for that matter, may not be as such to yours. That's probably why there is no definitive audio product posessing the absolute truth. It's all subjective. And personal. And most im... | |
| Rebuilt laser any good? ...four hundred bucks is about the price of a used one, CDM-9 and all. | |
| What to phase plugs do, and how do they function? They basically do three things: reduce the "beaming effect" of high frequencies, reduce the reflection of sound waves that can gather towards the center of the driver, and allow more air into the coil. The first two can muddle the driver's overall... | |
| Signal degration over length, source vs. output ? With tube amps, I would favor keeping the speaker cables on the short side. Two reasons, mainly: first is that tube amps give their push with voltage instead of current, so limiting the voltage drop from amp out to speaker will conserve power - wh... |
