Please tell me why I should avoid Ashdown amps? (aka why Ashdown are just great!)

To be honest I love ABM and MAG heads but their cabs leave a lot to be desired. I have had several different types, ABM, RM, MAG over the years and for me a Rumble 500 blows them out the water.

I have my Ashdown CTM-300 absolutely purring today

My favourite amplifier of all time

I've got an RM800 evo III on its way to me, so look forward to trying it. I've never owned an Ashdown amp (I had a 6x10 cab once though). I have used them before though and have a question.

 

Does anyone actually use the drive, compressor and sub controls or are they just gimmicks best left turned off? I seem to recall that the ABMs I've used previously were much better with the compressor and sub completely off.
