In the early 1970s, I lived in a village 40 miles north of London, England, and regularly drove through an only slightly larger village called Houghton Regis. And every time I did so, this budding audiophile was thrilled to see a factory in the High Street with a nameplate proudly announcing that it was the site of Teledyne Acoustic Research's European operations. I was aware of the American brand because of a chance encounter with a pair of Acoustic Research LST speakers, and the geographical connection led to an increased interest in their speakers (footnote 1). A sort of local-boy-, er, local-multinational conglomerate-makes-good story. Sort of.

"The synergy is palpable between Triode Corporation's Japanese-made electronics and Acoustic Zen's loudspeakers and cables," wrote Jason Serinus earlier in this blog and I just wanted to add my 2 cents. As I had in many rooms at CES, I auditioned my recording of pianist Hyperion Knight performing Gershwin on the Acoustic Zen Crescendo speakers ($16,000/pair). The sound of the Steinway was sweet—perhaps a little too sweet?—and the soundstage was wide, deep, and stable.

I have never been a fan of transmission-line speakers. My experience has been that too often resonant problems in the line color the speaker's upper bass. But I didn't hear any such problems with the Acoustic Zen Crescendo speakers ($16,000/pair), seen here with designer Robert Lee. The Crescendo combines two 5" midrange units with magnesium-impregnated paper cones placed either side of a horn-loaded tweeter with two 8" woofers that use ceramic-coated "non-pressed" paper cones, these loaded with a transmission line venting at the speaker's base. Driven by a Triode Corporation 20Wpc TRV-845SE integrated amplifier ($6000), which uses two 845 output tubes running in class-A, and a Triode TRV-CD4SE CD player, the sound in this room was uncolored and extended at both frequency extremes, revealed by a superb recording of a female singer accompanied by a double bass.

The Acustik-Lab SR Bolero loudspeaker ($1580/pair) debuted at the 1988 SCES in Chicago. I must own up right from the outset that I know nothing about the Swiss SR Trade (Acustik-Lab) company. I do know, however, that Audio Advancements' Hart Huschens was getting an intensely musical sound from their little Bolero speakers, driven by the German Klimo Kent tube amplifiers, at the 1988 Summer CES. I immediately asked for a pair for review; in addition, Mr. Huschens sent along a pair of the matching Bolero Forte woofers ($920/pair).
