And it is the same with the amplifier with a rating of 0.05% or 0.01% of THD. The one with distortion levels less than 1% are not significant. And the one with insufficient headroom cannot deliver the sounds’ high accurately.ĭistortion Level : As the name suggests, distortion levels will indicate the amount measurement of the distortions in the amplifiers’ output concerning the input applied. The amp with high values of THD and S/N level produce good quality sound. Some amps specs also add the dynamic headroom as an indicator of sound quality. The other factors indicating the sound quality includes the S/N level or the signal to noise ratio represented in dB. The THD (Total Harmonic Distortion) or distortion of the audio amplifiers are the major parameters which denote the high quality of the amp. The power of the amp does not define the sound quality so don’t get the amp with high power rating check for the other specs which defines the sound quality as well. One can enjoy the 60 W amplifier with higher sound quality than the amp with 100 W power with the bad quality of sound. And the sound quality is a major factor since one wants better sound, not more sound. The amps’ real power rating is an important parameter but what enables you to get the perfect loudness you desire is what defines the sound quality of the amp. Sound Quality : Sound quality is the factor which directly relates to the output of the amplifiers. Speakers with high power rating are capable of delivering better performance. It provides all the info that we need to know while getting an amp. And it is an easy way to compare the amplifiers from the many available brands. The format of power specification was the contribution of the “US Federal Trade Commission” which is the standard format to represent the power specification of any amp. And this rating indicates that the amp can deliver 90 watts of average power for a channel in the speaker load of 8 Ohm with a maximum of 0.07% of total distortion of harmonic for the specified range of frequency. But with the audio speakers, the power means a lot more, an amp's power rating says for example 90 W/Ch RMS 8 Ohms 0.07% THD, 20Hz-20kHz.
Power R ating : The measurement of power takes place in Watts. Here are some of the main specs of stereo speakers which will help you understand the quality of the amp.

Price: We set a rough limit of $140, which let us include a couple of full-featured models from S.M.S.L.
#Home theater power amplifier Bluetooth
Features: Although we did test some amps that had only a volume control, we gravitated toward models that offered nice extras such as Bluetooth support and tone controls.For example, we didn’t test both the Lepai LP-2020TI and the Lepy LP-2020A. Duplicate products: We didn’t test what appeared to be the same amp under different brand names.We figured few people would want to spend time searching for one. Most mini amps come with a “lump in the line” power supply, but some do not, requiring you to purchase a generic power supply such as those used for standalone computer hard drives. Power supply: We tested only those amps that included a power supply.
We considered amps of all power ratings because our early tests showed that even those with the weakest power ratings were adequate for typical home listening levels.
