| Efficient speakers v. less efficient speakers Short answer: no. You cannot generalize that higher sensitivity speakers paired with a low powered amplifier is equivalent to a high powered amp and low sensitivity speakers at a given sound pressure level. It depends on the quality of the amps an... | |
| When is unequal, equal? A difference of 8 feet will not make an audible difference. This is easily shown with the math, but without the boring details:Assuming the speakers have a 90 dB/2.83V-m sensitivity at an 8-ohm nominal impedance (1 watt) and that the speaker cable... | |
| Dedicated power,long power cords - waste of time? My 2 cents says go with Wiremold. It's the safest (i.e., legal) and most cost effective way to solve problems such as yours where behind the wall wiring is impractical. | |
| Speaker cable gauge and amplifier power One thing that I found interesting is the wire guage used INSIDE speakers from the terminals to the drivers. We hook up our 8-ga hoses to speakers that use 16 or even 18-ga internally. This renders anything larger before it moot. So unless you nee... | |
| Amp Ground Plug - Safe to Remove? The purpose of the ground plug is to return a fault current, such as a live wire touching the equipment chassis within, back to the panel. This does two things: it reduces the chance of shock or worse, and it enables the circuit breaker to trip - ... | |
| can a power regen. eliminate ground loop hum etc? First check to make sure the incoming cable service is properly grounded to the electrical ground (water pipe or ground rod) of your house's power service. Call the cable company or an electrician if you're not sure how or what you need to look fo... | |
| Shouldn't amp reviews employ multiple speakers? I would agree somewhat. Using one set of speakers that you are familiar with will enable you to discern differences in amplifiers more readily. Especially if the speakers have a quality of being revealing - such as the Thiels - and are considered ... | |
| Power Amp Tubes Blowing - what's wrong? One thing to check is your ac power. If you have too high or too low voltage, this could cause tubes to fail quicker. | |
| Problem with AC and how to solve it Or it could be that there's DC present in the house power wiring at certain times of the day. DC will cause a transformer to buzz. This is a power quality issue; there are power conditioners out there that can address the problem such as PS Audio,... | |
| Electrical issue If you plugged everything into one outlet, then ground loops are not the problem. It is most likely caused by either external RF/EMI interference or power line noise which may be in the power coming into the house (yes, the power company xfmr can ... | |
| What does 'Fast mean? I take "fast" to mean how quick the output of a device can follow a change at the input - which would pretty much describe the above impressions of transients, attack, etc. As for cables, well... they either do the job or they don't. Poorly design... | |
| The last 5 ????? Ah, but you are forgetting the Audiophile Paradox: the more you improve upon the system, the closer you get to the actual ideal - the cumulative losses of the recording chain. | |
| slight noise concern with lamm amplifier? What you describe is normal for almost every amplifier, preamp and phono stage. That noise is caused by the normal operation of the electronics which the speakers pick up (the more sensitve the speakers, the farther away you'll hear it). As long a... | |
| Question about sound below an amps frequency specs Unless there is a reason to limit the bandwidth of the amplifer, the low frequencies will not be intentionally filtered just outside the published specs.The frequency response of an amplifier is specified with a dB range. Your amp may be 20-20k +/... | |
| Popping from light switches and refrigerator It seems to me that your problem is from one of two sources: the refrigerator or the power company. The refigerator motor contacts, brushes or pull-in relay could be arcing, leading to induction or impules noise in the entire house wiring. These v... |
