Since my phono pre. and line stage have floating transformer outputs I have found (on the suggestion of Kevin Carter of K&K Audio) that connecting to the secondary side of the input transformer and using it as a CT grid choke gives the music a more dynamic and realistic presentation. As a bonus I can use the primary side of the power amp's input transformer as a galvanically isolated line out to drive my sub-woofer. As an aside, my DAC (PCM1794) is incorporated into the line stage. The balanced current output of the DAC chip uses two pairs of resistors to accomplish the I/V conversion and the balanced signal is routed directly to the grids of the line stage's diff. amp. No filter.
