"You're listening to the Jadis SE300B amplifiers with the Infinity Composition speakers?" a certain Stereophile reviewer asked, with a touch of disapproval in his voice.
"Yes, why not. Very efficient. Recommended for use with amplifiers with as little as 10 watts of power. What's more, the Jadis amplifiers and the Infinity speakers look very elegant together."
"Well, I don't know. But those Jadis amplifiers are very soigné, shall we say, and they would seem to demand equally refined speakers…

I listened to music using my Rega P3-24 turntable, NAD C 515BEE CD player, Parasound ZphonoUSB phono preamplifier, NAD C 316BEE integrated amplifier, and Kimber Kable 8VS speaker cables and PBJ interconnects—a pretty rad system, if I do say so myself. The DefTech StudioMonitor 45s were secured with small globs of Blu-Tack to 24"-tall Target stands, while the components rested on my Polycrystal equipment rack. Source components and amplifiers were plugged into a Furutech e-TP60 power conditioner, itself plugged into a Furutech GTX wall receptacle via an AudioQuest NRG-…
I examined the performance of one of the DefTech speakers with DRA Labs' MLSSA system. I used a calibrated DPA 4006 microphone to measure the speaker's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield responses. I estimated the SM 45's voltage sensitivity at 86dB(B)/2.83V/m, which is typical for a small speaker like this but well below the specified 90dB. The nominal impedance is specified at 8 ohms; while the plot of impedance magnitude against frequency (fig.1, solid trace) remains above 8 ohms in the upper midrange and treble…
