Learning never ends and the GR10e is a result of a constant desire to look at designs and materials and improve upon them. A higher level of precision and new materials allows for the performance of the GR10e to add frequency extension in both the high and low ranges as well as reducing distortion.
"...for the mid-band: its shock and awe! With enormous dynamics, extraordinary definition, and wide-open soundstaging, the GR10s are glorous midrange performers. This is where most of the music lives, and it lives big-time in the GR10s."
