I have narrowed my search for a new amplifier down to these two candidates. However, I haven't tried either one of them yet. I did order an AG-500 online and have the option of returning it if I am not satisfied but it hasn't arrived yet. Here is my question... These amps seem to be close in price ($1200-$1400) and for the most part, close in specs (750 vs. 500 watts, 2 channels, 1 clean & 1 OD, etc). Can anyone who has tried them both please comment on the OD channel of each? I have read a few reviews of the two but I am looking for some "real world" info. I have read everything I could find online about the technical aspects but I need more info.
