Audio Systems: Pre Amps, korg oasys keyboard, american music supply

Question
I'm using a Korg OASYS keyboard and I want to warm up the sound a bit...so I'm considering buying a high-end preamp (2 channels).  What do you recommend?

Answer
the magic word is 'warm'. i feel your best effect would come from a tube preamp. since i've been disabled, i haven't been keeping up with who makes them now, i've only been away for a few years and alot has changed. as far as manufacturers, anyway. just do a search for tube preamps and i'm sure you'll find alot to look at.but absolutely, for warming up the sound especially of the digital keyboards, tube preamplification will be exactly what you are looking for. try ' american music supply' that's a place to start.
