This may be a reach as I'm on a smaller scale than you, I like my Levinson with Pass, I still have Pass pre but switched from Pass amp. Brian of Bricasti used to be with Levinson and I like his DAC quite a bit. The way the Bricasti was set up the times I heard it, I found it to be quick and nimble with a smooth presentation, not warm, just a nice musical presentation. I suspect it would have nice synergy for you.
To my ears I found the Direct Stream to lean some more analytical than Bricasti and Lampi fuller than both, warm but not overly so.
I think Lampi would have synergy bringing a fuller presentation. It depends on which way you want the system to lean. In my system I found staying with balanced circuits to sound better. That's not always been my experience, but it was when mixing the Pass & Levinson.
There's a good Pass following here, I'm sure you'll get some good feedback.
