How Does Amplifier Energy Efficiency Affect Fidelity?
I'll look at the expression "power efficiency" which informs you of just how much stereo amps squander to help you select an amplifier.
The less efficient your amp is, the more power is going to be wasted which leads to a number of issues: Low-efficiency amps will waste some energy as heat and therefore are more expensive to operate in comparison with high-efficiency products because of the higher energy consumption. Amps that have small efficiency normally have various heat sinks in order to help dissipate the wasted power. Heat sinks and fans need room and are expensive. The amplifier therefore will turn out to be pretty large and expensive. In addition heat fans are going to create operating noise. Low-efficiency amps additionally require a good amount of circulation around the amplifier. Consequently they cannot be put in close spaces or within air-tight enclosures.
Given that low-efficiency amplifiers are going to provide only a small percentage of the power consumed by the amplifier as useful audio energy, the amp needs a bigger power source than high-efficiency types resulting in more expensive. Further, the thermal stress on the circuit board components and amplifier materials is more severe and may even lessen the dependability.
You should search for the efficiency value when on the lookout for a music amp. The best spot to check is the amp data sheet. Power efficiency is often shown in percent. Different amp architectures deliver different power efficiencies. Class-A amplifiers are amongst the least efficient and Class-D the most efficient. Standard power efficiencies vary from 25% to 98%. From the efficiency percentage it is possible to work out how much power the amp will waste. An amp having a 50% power efficiency is going to squander half of the consumed energy. An amp that has 90% efficiency is going to waste 10%.
Please note, though, that efficiency is dependent upon how much energy the amp provides at a given moment. Since every amp is going to need a certain level of energy, regardless of the level of energy the amplifier provides to the speakers, the amplifier efficiency is larger the more power the amp delivers and is usually specified for the highest power the amplifier can handle.
In order to figure out the efficiency, the audio power that is consumed by a power resistor that is connected to the amplifier is divided by the overall power the amp consumes while being fed a constant sine wave tone. Ordinarily a complete power report is plotted to display the dependence of the efficiency on the output power. This is why the output power is swept through different values. The power efficiency at every value is tested and a power efficiency plot created.
Switching-mode amplifiers use a switching stage that leads to a certain level of non-linear behavior. Therefore Class-D amps usually offer lower audio fidelity than analog Class-A amplifiers. Therefore you will need to base your decision on whether you require small dimensions and low energy consumption or maximum audio fidelity. Then again, digital amps have come a long way and are offering better music fidelity than in the past. Class-T amps come close to the music fidelity of analog amplifiers. Due to this fact choosing a switching amplifier with good audio fidelity is now possible.

BOSS PH5000D 5000 WATT MONO D CAR POWER AMPLIFER AMP
I'm not sure what you want to know, but I would HIGHLY advise NOT purchasing anything from boss. Also, stay away from: legacy, lanzar, hitron, pyramid, dual, jensen...they are all junk and have high failure-rates. Spend the extra money to get something from rockford, alpine, mtx, kicker, JL, audioque, cadence, sundown...you will have a MUCH better sounding system and it will last.
Also, that amp has 160amps worth of fuses which puts the MAX wattage for a 14.4V electrical system at 2304W. This means the RMS wattage at 1ohm is likely around 1500W, and at 2ohms probably somewhere around 1000W...so don't believe the huge numbers they are touting.
Griffin's Twenty audio amp gives AirPlay 20 watts per channel (TUAW)
Griffin has announced an accessory called Twenty, a small audio amplifier that
will accept audio from an AirPort Express to drive unpowered speakers. The
Twenty includes a TOSLINK cable to deliver pure digital audio from the AirPort
Express to the unit, and additional connectors in the back allow you to plug
speakers right in.
As the name implies, Twenty delivers 20 watts per channel of 2.1 audio. The
unit's top includes a nifty and well-thought-out adapter that allows you to
plug your AirPort Express's power plug directly into it, which means you'll
only need one outlet to power both the AirPort Express and the Twenty.
Audio can stream from your Mac or iOS device to the AirPort Express via
AirPlay, and from there audio passes from the AirPort Express directly into
the Twenty. As helpfully noted on Griffin's website, you'll have to purchase
your own AirPort Express and speakers.
Griffin's Twenty looks like a nice, miniaturized replacement for a full-
fledged audio amplifier. I've already got one AirPort Express in my living
room tied directly into my 7.2 surround sound system, but Griffin's Twenty
would be ideal for the secondary AirPort Express in my office.
Griffin hasn't ...
