The written history of jazz is founded on iconic recordings, and the oral history is full of legendary gigs. The Five Spot, a smoky little dive at 5 Cooper Square in what is now called the East Village, was, between 1956 and 1962, the site of more than its share of historic engagements.…

To cover the entire audio spectrum with only two drivers is a hard task, and most two-way systems end up with a crossover frequency around 2kHz—[at the top of] the critical midrange octaves. The Tablette, on the other hand, manages to reproduce almost the entire middle range…

If you can play a guitar and you're from New Jersey, you're automatically doomed to a lifetime of answering one question: How much have you been influenced by Bruce Springsteen? How much "Jungleland" do you feel is lodged in your unconscious mind?

The brothers Delevante decided to have their Springsteen but also devour a whole range of other influences…

As a rule, I'm not impressed with $200/pair speakers that…

Most audio engineers split hairs. Eelco Grimm splits microseconds. His expertise in high-precision audio laid the groundwork for Grimm Audio, the Dutch venture he cofounded in 2004 with fellow electrical engineer Guido Tent. The company's master clocks and DACs, developed for both the pro audio and home hi-fi markets, combat tiny timing errors and jitter that can blight digital audio.

But Grimm Audio's engineering acumen also extends to the analog domain, as evidenced by the LS1c active speaker system that made the cover of Stereophile's April 2025…

van Bakel: I listened to the LS1s with and without the SB1 subs. Even without them, my brain believed it was still hearing the entire bottom octave in bass-heavy music—even though according to the specs, the main speakers bottom out around 35Hz. What was happening?

Grimm: In two-way mode, we use DSP to correct for the absence of the subs, and we can get the LS1 to play as low as 20Hz all by itself. But that does greatly increase cone excursion, so distortion sets in. That distortion has a way of accentuating the very low…

The tubes in the preamp chassis and the power supply were installed when I unpacked the two shipping boxes, but I checked that they were correctly seated before starting the testing. I performed a complete set of tests with my Audio Precision SYS2722 system after powering up the preamplifier and letting it settle for 30 minutes.

The Treehaus inverted absolute polarity with all of its inputs and outputs, which is what I would expect from a circuit that uses a single triode in the signal path. The Treehaus's input impedance is specified as a minimum of 40k…
