Even if it has a better SINAD, nobody can hear a difference. Bear in mind that those 2 amps show better figures than most power amps. Amir's tests are to some extent overkill.
With regard to biamping, it will provide improvement in some situations but for most home audio systems, it's not necessary. Active biamping involves more expenses as you need two amplifiers instead of one, and a separate electronic crossover to divide the frequencies before connecting the power amps.
In my HT system, I'm biamping the three front speakers because I'm using a low 200 Hz crossover frequency, between the subwoofer and the mid-bass drivers. A passive crossover frequency that low would require a high inductance coil, resulting in a higher resistance in series with the LF driver. That would affect an amplifier's damping factor with resulting loss of good transient response.
Recently a reader of Audioholics asked us about the differences between bi-amping and bi-wiring, and what kind of effect they could have on his system. Read on to see our reply. Discuss "The Difference Between Bi-amping and Bi-wiring" here. Read the article. So how are you connecting the...
