Donny, it has nothing to do with a particular brand...
Most people will admit the Ketron has superior drums...period..

My point about listening to your keyboard and compare it to the Audya..has more to do with it's class..

PSR canidates (and Prelude/GW8)..are not buyers of Tyros3 and Audya...simple math and economics...but don't think for a minute there are not differences between a $1.000-$1,500 instrument and a $4,500-$5,000 instrument..

Quality differences in construction, converters, samples..and other major differences we are not privileged to know about..Remember we are comparing within the same brand..

There will be a fair share of buyers in any class for many reasons...PSR910 buyers for lighter weight and a lighter cost..Tyros3 for the best they can get for their Yamaha investment..No right or wrong..just different frames of mind..and budgets..

The Audya buyer is interested because the board represents the best sounds/styles in a closed system arranger...and they can afford the price...So for every Don M, and Frank, and Semi...you have Me, you and Ian..
