Haven't used it with a DHT preamp but have used it with Rogue Audio 99 Super Magnum with Mundorf Supreme Silver/Oil with psvane cv-181 and tj full music and now with a Rogue Audio 99 with the Supreme Silver/Oil Caps(with electroharmonix gold ins). I've owned the Sit-2 for about a year now and it's probably the most transparent amp I have ever owned. Quite impressive really. I can't say the amp has a particular sound in that it will just present exactly what is presented to it. So you really need to pick your front end to taste. you can make it as lush/tubey or as neutral as you want it. What it does convey is detail in spades.
