I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the NEAT Acoustics Iota Alpha's frequency response in the farfield, and an Earthworks QTC-40 for the nearfield responses. The first challenge I faced was deciding on which axis I should place my microphone for the farfield measurements. Sitting on its spikes, the Iota Alpha is 19" high, and its tweeter is just 17" from the floor. However, the section of the front baffle on which the tweeter and midrange unit are mounted is canted back at 30°, which aims those units directly at the ears…

All of the players were auditioned in a system which consisted of the Jeff Rowland Design Group Consonance preamp, Threshold SA/12e monoblock power amplifiers, and Apogee Stage loudspeakers (on their optional stands). The connection from preamp to all players was via 1.5m lengths of AudioQuest Lapis. Balanced Cardas Hexlink cable was used from preamp to amplifiers. The Stages were bi-wired with Symo cable.
Comparisons were performed with the CAL Aria Mk.III, Mod Squad Prism II, and the Sony CDP-77ES C Dplayers and the Meridian 203 D/A processor.…
I checked the AC voltage from chassis ground to main (house) ground to determine the correct line-cord orientation. The NAD measured just over 10V (vs just under 19V the "wrong" way—and the plug is not "keyed," footnote 1); this voltage will be shunted to ground when the player is connected to a properly grounded preamplifier.
In order to determine the cause of the slight tracking problems encountered with the player, I checked it with the dropout tests on the Pierre Verany Digital Test CD. The results were perhaps indicative of the problem but not…
