I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the GoldenEar Triton One's frequency response in the farfield, and an Earthworks QTC-40 for the nearfield responses. The Triton One has a very high specified voltage sensitivity of 92dB/2.83V/m. My B-weighted estimate was 91.3dB(B), which is within experimental error of the specification.

The One's nominal impedance is specified as being "compatible with 8 ohms." The solid trace in fig.1 reveals that the impedance magnitude ranges between 3 and 6 ohms for much of the audioband,…

I measured the second sample of the Cambridge Audio Azur 851A (serial no. FE C10427K 1205 0137) using my recently recalibrated Audio Precision SYS2722 system (see www.ap.com, and the January 2008 "As We See It"). Before performing any measurements on an amplifier, I run it for an hour at one-third its specified maximum power, which, thermally, is the worst case for an amplifier with a class-B or -AB output stage. I cut short this preconditioning with the Cambridge 851A after 30 minutes, however, because its case was getting very hot—the top-panel grille over the…

Reid Anderson: The Vastness of Space
Reid Anderson, bass; Andrew D'Angelo, alto saxophone; Bill McHenry, tenor saxophone; Ben Monder, guitar; Marlon Browden, drums
Fresh Sound New Talent FSNT 096 (CD). 2000. Reid Anderson, prod.; James Farber, eng. DDD? TT: 64:35

Before he rose to jazz renown as bassist of the Bad Plus, Reid Anderson put out two keeper Fresh Sound albums and then this, a quintet session that should rank as a classic of turn-of-the-millennium New York jazz. Two tracks, "Prehensile Dream" and "Silence Is the Question,"…

The Smithereens: Especially for You
Enigma ST-73208 (LP). 1986. Don Dixon, prod.; James A. Ball, Gray Russell, Carol Cafiero, Paul Special, Frank Pekoc, engs. AAA. TT: 44:14

Especially for You isn't just a great and great-sounding rock album, it might just be the rock album. "Blood and Roses" got all the attention, and yes, it truly does reach in and grab your soul. But the real stunners are the two cuts that precede it, "In a Lonely Place" and "Behind the Wall of Sleep." Suzanne Vega's background vocal in the former is spectacular, and…

The Spencer Davis Group: The Best of the Spencer Davis Group
EMI America CDP 7 46598 2 (CD). 1987. AAD? TT: 34:06

If you've had your fill of Auto-Tuned and/or Pro Tooled tunes and crave musical authenticity, travel back to mid-'60s British R&B—specifically, to this collection. It may have been guitarist Spencer Davis's group, but it was Steve Winwood's singing and keyboards that put the band over the top with two Stateside megahits, "Gimme Some Lovin'" and "I'm a Man." The formula for all 12 tracks here is simple enough: The group pours…
