Sideways,
Several years ago I had the Sonic Frontiers SFL-1 in my system. The preamp mates well with an ARC tube amp.
What make and year is the 12AT7 tube in the preamp?
From the factory the preamp came with 2 tubes. One was a 12AT7A (Ei) and the other was a Signature CV4024/M8162, a Mullard tube. The Mullard was the preferred tube for my taste in the preamp. The (Ei) tube caused the preamp to sound more like a SS preamp to me.
