The reason I am asking is that I own an Outlaw 2200 monoblock which is class G/AB. From what I've read it operates in AB mode until it peaks up to about 80 watts, then switches over to G mode from there. How does this affect the efficiency or operation of the amp? The outlaw has an output of 200 watts. Would a comparable amp that was AB right up to it's maximum output of 200 watts be considered better? I guess what I'm asking is does the class G operation of the amp somehow detract from it's overall quality... |

If the amplifier operates in class AB up to 80 watts output, it is, for the most part, only the ocassional, micro-second long peak that drives the amplifier into class G. Typical requirements in a home system would mean you are hearing class AB 99% of the time since you are unlikely to use even 80 watts continuous power (20 or 30, or less, is more common with moderately efficient speakers). If the question is whether class G operation for that small portion of your listening time detracts from the performance or sound quality of the amplifier, I would answer, "No, it does not." A "typical" class AB amplifier might sound better or worse, depending on how it is built and what speakers you connect to its outputs. . |
