José:
THANKS for the links to the highly informative articles about IEMs (in the ear monitors). Seems the stage venues in the article are more rock band oriented. I'm still trying to figure out if this 'IEM' scenerio would work for my more initmate one man band style setting or not.

I'm wondering if you might have just MISSED READING my questions to you earlier in this thread (see above).

I'm really curious to find out if you would consider switching to an arranger that didn't have 'built in' speakers (like the Tyros or SD1) and feel comfortable enough to rely solely on 'in your ear' headphones for monitoring while performing. Do you think you would miss having built-in speakers? Thanks.
