I listened to the top Supratek DHT, two box, tube regulated preamp last week. It has a switch allowing the owner to switch between transformer coupled and capacitor coupled. I prefered the capacitor coupled option as the highs were less grainy, more extend with improved smoothness. It this design the transformer option limited the top end.
This got me to thinking more about direct coupled as the best option. It is an interesting design.
