I am glad I still have a good friends here loving their BCL like I love mine.
Since I love my LCD-2 more than HD650, I tuned BCL gain setting for LCD-2.
Low gain definitely have more resolution, livelier treble (but still smooth), but a little colder and lack of bass dynamic and punch, so I always set medium gain for my LCD-2.
I am so satisfied with the balance (tonality, warmth, resolution and punch) from medium gain I do not want to bother to test the high gain, which I suspect, looking at the trend, will be even more punch, but even more less of resolution.
I noticed, gain can affect the sound tonality quite a lot!
I don't test the gain so much with HD650. I am curious which gain do you guys use to drive HD60?
Maybe I do not so much like HD650 sluggish bass, but I find I like BCL better suited for HD800 than HD650. I don't like HD800 sibilance too, btw.
