Lamm + Wadia. A Good match?

My recommendation is to go direct. The digital volume control is the best invention in audio. You have to set it up properly though. Pre-amps add color if you want it abut at the cost of resolution, timing and separation of instruments. That should be a dynamite set up run through the balanced outs. Good luck

I've had BAT VK30, BAT VK 51, Pass labs Aleph P and a Hovland pre-amp in my set ups and running direct has been best in all situations. You have to give yourself some good audition time. I'm always shocked to hear people say they can't get the Wadias down in volume or that the digital volume throws away resolution. An analog volume pot loses much more. I've even had techs from companies that don't use digital volume tell me its no contest as far as resolution. The 581 will go to .25 volts with the dip switches.

Nelson Pass has an article on a buffer he made that makes sense of the volume control argument. You have to breeze over the technicla stuff to glean the salient points.
