True, but the graph doesn't look quite as nice as the SD9.Also SD7 that is cheaper…
The SD7 looks more intense in the high-mids / lower treble region. I wouldn't be surprised if they are a bit fatiguing.
Treble extension looks much better on the SD9.
These are only graphs... but they are all we have at the moment!
And yeah, maybe GD3A is worth try!
