acording to BobKay the M80HP is far more above the M80 v3.
Ian mentioned, unless I am using the M80v3 at high volumn I would not notice a difference between the v3 or v4.
I look forward to hearing M100's, I'm certain Bob's has no regrets.
I'd assume Ian was commenting on a standard M80V3 vs standard M80V4?
I hate to say anything negative about the M80, it was a nice sounding speaker. I like the HP's better. Will you, or any one else? I can't say.
The tipping point for me was the excellent trade in value which was too good to pass up (a second time).
The subtle improvement and new level of satisfaction is the bonus.
