PMChuck thanks for your suggestions, I will certainly go with the studio monitor idea. The PX-5S arrived this morning and I connected it to an old (very) Roland Super 60.......it was awful, I was very disappointed. So I looked around for something else to try, I disconnected my tiny pair of powered speakers from my PC and had a go with them, unbelievable difference. I can't wait to get a decent pair of 5, 6 or 8 inch powered monitors with tweeters, but which ones? Here where I live, Southern Brittany France, there is very few audio shops to search, but I do have access to several internet shops that have a large choice and good prices. Over on the Korg Forum there is a similar discussion with quite a few options suggested. http://www.korgforums.com/forum/phpBB2/viewtopic.php?t=62965&postdays=0&postorder=asc&highlight=monitor&start=0
