Not to dissuade you from your original choice in integrated amps, but you may want to check out Mystere instead. You get additional head room regarding power. This is the "high end" division of the same company that offers PrimaLuna products.

I own the Mystere CA11 preamp and really like it. I traded in my PrimaLuna preamp for the Mystere and have never looked back.
