In my humble opinion, the best starts with being Differentially Balanced= TRUE balanced, but to appreciate what that does, your amp needs to be DB also
In that vein, though I've never heard it, Tortuga Audio preamps tech is first rate and likely to be up high on any list,
it would be on mine, but I am running my Oppo 105 via VVCs (WireWorld series 8 XLRs to EVS 1200 amp) to very good effect. I believe Tortuga has a return policy but at 2K Im afraid I would love it too much
