Comparing amp's loudness at equal gain & volume settings is utterly futile - whichever has the greatest dB gain at that setting will win, not the one with the most power. By that method every old TE amp was way louder than my old SWR/QSC rack - but push both to clipping (which required much more knob turning on the rack) and the 3000W rack rig unsurprisingly left the 300W TE amp in the dust.
A Shuttle 9.0 is only 1.8dB more powerful than a Shuttle 6.0 - which is only a slight amount. It isn't like going from 50W to 350W, it's like going from 50W to 75W.
So if the Reidmar is an honest 250W it won't be much quieter than the other more powerful micro-amps, especially if their ratings are less honest.

Alex, I am so glad you joined this thread. I had a Shuttle 6 and moved up to a shuttle 9 and it really did not seem that much louder. Certainly not the massive just I was expecting so your explanation has cleared up why that was.
I was speaking to EBS about the Reidmar and they said it does not automatically limit the signal anywhere before the power amp which gives more headroom and preserved definition of tone even at high volumes, where as other class D amps [color=#000000]feature a built in limiter that reduce dynamics and limits and level out the low end at high volume, which makes the tone lose definiton - only to prevent the power amp from clipping.[/color]
