I think the difference is mostly, if you are a self taught, 'home' arranger player, you have never probably played in a real band. Most of what you have heard comes off of CD's and the like. So, you'll tend to prefer a keyboard that has this kind of dynamic.

If you ever played in a live band, though, you'll be used to something a bit more punchy and in your face. More raw, more difficult to ignore...

If you are doing primarily home recording and songwriting, the Yamaha's help make it easier to get 'close' to a CD sound with little technical recording skill, but once again, the more 'live' sounding arrangers, once compressed and limited correctly, tend to have, IMO, a better CD sound, due to them, just like a REAL CD, starting with a more live sound.

But I believe both 'sounds' have their place. If I was doing a restaurant 'background music' type of gig, I'd shoot for the Yamaha's. Very 'Muzak'-like, nothing jumps out, nothing disappears. VERY 'polished' (like Ensnareyou, it's not MY preference in 'polished', but it is ONE type ), very smooth.

If I were doing more in your face type gigs, I'd shoot for something else, a Roland, a Ketron, a Korg...

To be honest, I think it is fairly easy to hear these sonic differences from the factory demos themselves. If you can't tell the difference, bruno, then it doesn't really matter... and if you can, only your OWN opinion really matters, in this case, anyway!
