I was thinking about the next one up, the RA-500 ( [url="http://www.thomann.de/gb/alesis_ra500_amplifier.htm"]http://www.thomann.de/gb/alesis_ra500_amplifier.htm[/url] ), which should be plenty loud enough I would think, infact, the RA-300 could be too, the no fans thing is what sounded good to me too, have you ever had any issues with yours?
