Thanks for the responses again.
Cyctocycle - I didn't realise the Lamm's were not fully balanced. I can output all balanced or unbalanced in 7.1 if need be (I have the all the cards too!) but single ended has proven to be susceptible to hum in the past - this might be the case with the Lamm, but it was with my Krell.
I'll look into the Thetas - but think if thst was my route, I'd be better off as earlier suggested with DSP 8000's.
