Roland,
I think you probably got your amp just before the down grade of their product lines. I believe they were bought out (can't remember who) and the new owners decided to target the mid-fi car audio market. If I am correct they changed all (most) their amps to Class D amps. They are much cheaper and easier to get big watts out of. Unfortunately, as with all Class D amps the SQ is not up to par with other types out there. At least not yet....
