| How low can one hear Huh?? Say again I can't say for sure why that statement can be made. I've read things on hearing that says youngin's can hear down to 16 Hz and the range of normal hearing is 20 Hz to 18 kHz. I can hear (barely) the 20 Hz test tone on the Stereophile Test CD . Gr... | |
| "High Current" The "wattage" can decrease and the current can increase. Look at your formula - if the current decreases by a factor of 10 and the voltage increases by a factor of 20, the wattage doubles. As far as the the power rating of the SimAudio i-5, it's d... | |
| Need help on power supply caps If the amp has 35-amp/400V bridge rectifiers, it won't be a problem; if it's less than that (15, 20, 25-A), then see if it's possible to replace them with the 35-A, the largest rating available, if you want to be sure. I agree with Herman, the exi... | |
| Egglestone Andra 1 tweeter "crossover" Have you considered the possibility that the "bright" might be from the room surfaces and/or speaker positioning? | |
| Slew Rate? The slew rate of an amp will tell you how fast the amp is capable of reproducing an output signal with respect to the input signal. The output signal of an amplifier is similar to an enlarged xerox image of the input signal's magnitude. But the in... | |
| Do power conditioners help with unwanted hum/noise In some cases, even dedicated circuits or power conditioners might not help. If the house power system is not grounded properly or there's excessive current in the neutral wiring (dimmers, fluorescents, computers, etc), or if strong external RFI/E... | |
| Switching polarity of tweeter in two-way design Not really. That will only work if the crossover frequency's wavelength is exactly twice the distance between the tweeter and midwoofer. And it would only work at that one frequency. | |
| 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. |
