I’ve tried my D400 on a pair of Martin Logan CLS electrostatic loudspeakers. These have a challenging impedance, from the high 30+ ohms in the bass to under 2 ohms in the treble. They are not very efficient either, around 84dB.
The results were less than satisfactory. The volume had to be cranked up high, and even then, the amps were not playing very loud. They started to get fairly warm as well.
Would the new 1000 Expert Pros fare any better? I’m not interested in specs. I want to know if anyone has tried the 1000 on speakers with challenging impedances.
For comparison, a pair of bridged Class D Primare 30.5’s producing 500 W/channel worked much better on the CLS, remaining cool.
Not surprisingly, a pair of 120 watt Quicksilver tube mono blocks produced the best sound. Effortless, transparent, and very engaging, showing why tubes remain a viable technology in 2018. Sad but true. For all the tech in a D400, sonically they were no match for the Quicksilvers.
