I used DRA Labs' MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the TAD Grand Evolution 1's quasi-anechoic frequency- and time-domain behavior in the farfield. I used an Earthworks QTC-40 microphone, which has a small, ¼" diameter capsule, for the nearfield responses. I examined the loudspeaker's impedance with Dayton Audio's DATS V2 system.

It's not their fault, or at least sometimes it isn't. Even the good ones can't tell you how something will sound to you—let alone make you feel, the ultimate point—in your own room. As helpful as they may be, they can't address the elephant in the listening room: synergy.
Have you ever been to an audio show where a component in a demo sounded wonderful, only…
Next up: Desert Lady/Fantasy (CD, Columbia CK 57856) by Toshiko Akiyoshi and her 16-piece Jazz Orchestra, featuring Lew Tabackin. I played three minutes of the first track, then three of the next, the title track. The soundstage was grand: flush with detail, big pictures, and colorful images, except this time, during some parts, its pacing and images seemed to drift more than usual, none of which I had noticed on the Adderley CD, which is a much more sterile-sounding recording than this more harmonically tufted Akiyoshi one.
I substituted my iFi DSD Diablo DAC, whose character is…

I measured a different sample of the Octave Audio V 70 Class A than that auditioned by RS. Mine had the serial number 22018130 and was not fitted with the optional phono module. As RS primarily used the balanced line input and KT120 output tubes with the Power switch set to High and the amplifier connected to the Super Black Box external supply, I performed a full set of measurements in that condition. I then repeated some of the tests with the single-ended inputs, then without the Super Black Box (footnote 1), and finally with KT88 tubes replacing the KT120s and…

I have a weakness for these brands, which is why I purchased an Anthem STR integrated a few years back. Five grand for a Stereophile-recommended, class-A-rated "watershed product" (in the words of TJN), with room-correction built in? Sounds good to me, literally and…
