Thanks, Mitch2. Yes, a bit tricky trying to find an NAT audition piece, as I know of only two distributors/dealers in the States, and doubtful they'd be willing to do so. It is for the same comparative sonic traits you mention that I felt the combo might go well together.
NAT Symmetrical + Merrill Veritas
Recently acquired a pr of Merrill's Veritas monoblocks and thoroughly enjoying the sonic improvements they have brought. However, don't seem to have great synergy with my existing Simaudio Moon P-5 preamp - a bit too solid state sounding, IMHO. Was strongly considering the NAT Symmetrical as a tube compliment to the Veritas. Has anyone had any experience with this pairing?
