Joe,
If I go for a Big 7 next year, it will probably be the SE version because it turns out my Soulution 520 Preamp is unbalanced through its XLR inputs. Cyrill Hammer said they could detect no audible difference between balanced and unbalanced, so they went for the less complicated unbalanced design. Based on the amount of jazz vocals I listen to, the Dueland copper or Jensen copper caps would probably work best for me, to provide a beautiful midrange. Elrog 300B or EML 45 Mesh output tubes for the same reason.

Awesome Ken. This is obviously my first Lampi dac. I know how good they can sound. I am hoping to go direct from this dac to my balanced 211 amps and be blown away. I am not one to eschew preamps but it might work really well in this case. When I consider another Lampi, it will probably be DSD only.
