| Special digital cable needed? The 75-ohm value is a "standard" of sorts. Basically, the reason for it is to keep the impedance between sources at a value where there is no signal reflection (which can cause jitter). Whether or not a 75-ohm cable sounds better because of it I g... | |
| Riddle me this: how is carbon a conductor? A few questions for Michael Wolff: from what I understand, the conductive properties of graphite come from the way the carbon elements are arranged. The carbon graphite crystal is a hexagon with only 4 carbon atoms bonded. This leaves one outer ri... | |
| Freezer Cryoed Cables... Why is this any sillier than:- Pacing half-cut rubber balls under equipment;- Painting CD edges green;- Brass cones that drain energy (only brass - nothing else);- $3,000 power cords;- Cable cooking;I'm sure there are other things to list that on ... | |
| What is "slope"??? Does the Casablanca give you the choice of sending the full signal to the subwoofer channels (i.e. SLOPE OFF)? If so, then why not set the subs to receive the full signal and let the sub's filter let in what it needs. But if you want to bypass the... | |
| What Causes Tube Noise at Start-up? If it only happens with the Mullards, then it is probably a grid short in the tubes. Once the tubes warm up, the short clears itself. One or more tubes are probably worn. A tube tester will confirm a grid short. | |
| How to do dedicated circuits with isolated grounds I did the same type of installation. From the main panel, I installed a 2-pole 100-amp breaker. From this breaker, a run of 1-inch EMT feeder to a 100-amp main-lug sub panel (check with your codes if your sub panel requires a main breaker). The fe... | |
| Can a transformer be replaced? Try Reference Audio Mods | |
| Tube pre for Forte 4a The 4a works great with Audio Research preamps. I had the LS2B - excellent combo. | |
| audio and photography parallels?? I don't think the parallel is as close to audio. A digital picture is not recreated by a "sample" of the image - it captures it whole, similar to film. Whereas the film image is created by a chemical reaction stimulated by light onto a finite numb... | |
| Is Clipping an amp always Audioable? Clipping is not always audible as clipping does not always occur at the full volume setting. If you have music with a high peak to average power ratio, then a slight increase in power will clip the peaks slightly (i.e., it'll chop off only the tip... | |
| Are There Any Inherent Advantages to Class A amps? I don't think the class of operation will (or should) make one amp be more advantageous over another. To answer the question directly: yes, there is an inherent advantage. It's the elimination of cross over distortion which means one less level of... | |
| Tube equipment use in high altitude? Did the tubed ICBM's sound more mellow than the solid state versions on detonation? (sorry) | |
| Class A Amplifiers and impedance dips No. Only if the power supply is capable - regardless of class - and only to a limited load impedance. | |
| Tube equipment use in high altitude? Tubes were used in the radios of World War II aircraft at flight levels of 25 thousand feet or more - the same types now sold as NOS. Also, these were the VT or military spec tubes which were built for the altitudes, vibration and temperature extr... | |
| Stress on Solid State Amps An amp is "stressed" much more by turning it on from a cold start than by playing it full volume for weeks on end. An amp driven to clipping occasionally or if played at higher power settings is more dependable than an amp that has been sitting id... |
