With my Tekton DI, I have used the McIntosh MC30s ,that had been completely re-done by Yves Beauvais, with Excellent results. Unfortunately had to sell them ... for financial reasons They could push them pretty hard ,even on techno or heavy Bass stuff. I also used the Rogue Audio St-100 tube Amp.It was still very good , but, I liked the Mc30s a little better . The rogue St-100 could have a little too much upper Mid-range presence , at times, but it could drive them much harder without clipping.
