Upgrade PWD MKI to MKII worth the investment?

There was a thread about this recently but I can't find it for some reason. In that thread I said I thought the Mk II was a definite upgrade but not a night and day difference.

A few people thought I was deaf or crazy, and I admit to being a little of both. They thought the Mk II was definitely a night and day upgrade.

You can find this discussed in great detail in the discussion forums on the PS Audio website.

OK, I found that recent thread:
PS audio PWD MK2 a real upgrade from MKI?

and it was started by you. That's probably why this one didn't get much response.

I did but I did not get much response either and some were ambiguous,
I like what I hear with the mkI, but I was expecting description of sound difference.
Thank you very much.
