I measured the Rogue Stereo 100 amplifier using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Before doing so, I installed the KT120 output tubes and, following the instructions in the manual, checked each tube's bias current. These were all around 50mA rather than the recommended 40mA, so, using the supplied tool, I adjusted the four trim pots. I checked the bias currents several times while performing the measurements, but none of the tubes had drifted from the recommended 40mA. The Stereo 100 has both balanced and single-ended inputs…

I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the Tidal Akira's frequency response in the farfield, and an Earthworks QTC-40 for the nearfield and spatially averaged room responses. I was neither able to move a speaker as large and heavy as this—each Akira's polished stainless-steel base alone weighs 70 lb—out of the listening room, nor raise it off the floor to measure it. I aimed the speaker across the room's diagonal to push back in time the reflections from the sidewalls, but the reflections of the speaker's output from the…
