Stereophile occasionally awards a Joint Recording of the Month, and Cecilia Bartoli's second recording of Vivaldi arias deserves no less.
Though we don't know over how long a period Bartoli recorded this album's 10 tracks, she finished the project with Jean-Christophe Spinosi's Ensemble Matheus, a baroque group…

Equipment used during the auditioning of the Maggies included Mark Levinson No.23.5, Audio Research Classic 60, and YBA 2 HC power amplifiers, hooked up to the speakers with 2m lengths of AudioQuest Dragon or YBA Diamond cable. The main preamplifier used was the French YBA 2, with the latest version of the Mod Squad's Line Drive Deluxe occasionally pressed into service, both feeding the power amplifier via 15' lengths of AudioQuest Lapis unbalanced interconnect.
Source components included a Linn Sondek/Lingo/Ekos/Troika setup sitting on an ArchiDee table…

Fig.1 shows the MG2.6's electrical impedance magnitude (solid line) and phase (dashed line). With a value averaging 5 ohms in the bass and 3.5 ohms in the treble, with a rise in between due to the crossover, the speaker is a reasonably demanding load in terms of current draw, though the phase curve indicates it to be resistive—ie, not significantly departing from a 0° phase angle—over much of the audio band. The MG2.6s shouldn't give good tube amps any problems as long as they're driven from the 4 ohm output taps. The very slight wrinkles at 50 and 60Hz presumably…
