"the LS-10 is noisy and not as good..."
In high mic sensitivity mode, the LS-10 is more sensitive and noisier than the R-09HR set to high sensitivity. Switch the LS-10 to low sensitivity and higher record volume for best results.
As Guysonic showed, the LS-10 has a bass roll-off below 200 Hz. This helps in some circumstances, hurts in others. To my ear, the R-09HR sounds like it emphasizes bass a little, so it sounds warmer. If you like music with bass that rattles the dishes in the kitchen cabinets, you'll prefer results from the R-09HR.
