Audio Systems: Preamp, korg oasys keyboard, dsp algorithm


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
Are you playing this through an amp or into a computer?  

There are some really cool new keyboard/Midi fire-wire and USB pods with some nice software or hardware pre's I can recommend.

Otherwise, I have heard great things about the Speakesay Dyno (very straightforward circuitry design).

Usually when you apply objective analysis to what people mean when they qualitively say they want "warm" sounds you find they expact a slight EQ bost in the low-mids and/or a slight low-end harmonic distortion.  For that I'd go with tubes.  Check out ART's Dual MP (or something similar) as it adds a tube gainstage to it's pre.  

The latest generation of tube modelers are also VERY good, Line6 makes a credible DSP algorithm.

If you're looking to go pro-studio, Yamaha Comercial Sound's various DSP units (costing as much as a Yamaha race bike) are top of the heap.

Let me know if you're looking for something more specific.
