My Cornwall 4's are moved by an arrangement of components that have proven to be very well matched to the task.. The PL EVO 400 Pre is sandwiched between a Holo May KTE DAC and a pair of AGD Audion Mk3 monoblocs. The CD transport is a Jay's CDT3 Mk3. The Primaluna pre uses NOS Mullards in the rectifier positions and a pair of NOS Amperex "Bugle Boy" 12au7's from the late 1950's in the gain positions. This took awhile to become a stellar setup as most of these components needed a lot of break-in. The PL was already broken in.
It did finally take some extensive fiddling with power cables and IC's to get everything just right, but that is par for the course.
