Agreed, a lot of times paper stats looks better than they actually pan at. That being said, when I reviewed the BL I found it powered the HE1000 sufficiently (didn't even need the Turbo setting) The LCD-4 is harder to drive so it will definitely require the Turbo setting but we will see how it performs for sure with the LCD-4 when I get the BL.
The HE6 out of the iCAN SE (same power output as BL) also didn't need the highest gain for full power on that, in fact putting any headphone on the full gain wasn't good, causing tons of distortion. During that test run, though, there may have been some missing earth issues, so I have to pour some salt on my observations. I haven't been able to make the test again with that potentiality controlled for.
