Duntech power needs -
I owned Duntech Princesses for 19 years. During that time I had the chance to try many amps, both tube and SS. Clean power was the key.
The Duntechs were deceiving because of their 90 dB rating. The crossover in Duntech models is quite complex due to the time/phase coherency design. Upon seeing the crossover board for the Princess, a friend commented that all it needed was a power line and transformer and it could serve as an amp! Also, the impedance dipped below 3 ohms at two different frequencies. Small amps need not apply.
Among the best results I experienced with my Duntechs was passively bi-amping (all that was possible with stock crossover) with pairs of VTL 225 monos (mid/tweet) and VTL 300 (bass) amps. It sounded wonderful but with 32 output tubes created too much heat for my room. The ultimate answer was a pair of Halo JC-1 monos rated at 800 watts into 4 ohms. Then I experienced full range, dynamic, and effortless sound. Oh yes, musical too.
