Analog Corner #323: J.Sikora Reference turntable and KV12 VTA tonearm Page 2

With the motors running and a stethoscope in my ears, I placed the stethoscope diaphragm on the plinth, as close to each of the four motors as possible without touching and heard complete silence. No matter where I put the stethoscope on the plinth, there was absolute silence. That's impressive and unusual.

I placed the stethoscope diaphragm in the same positions with the motors off, then started them. Usually, there's a low-frequency grinding noise that smooths out as the platter achieves speed. Here, I heard only more silence.

The 'table also passed the impulse "thump test."…

Lejonklou Entity phono preamplifier

Sometime around 483 BCE, in Kushinagar, the capital of the Malla Republic in what today is the Indian state of Uttar Pradesh, an aristocrat named Siddhārtha Gautama—known better to us as the Buddha, or the Awakened One—passed away. For 45 years, he had wandered the North Indian River Plain teaching a method of overcoming ignorance, craving, and the cycle of death and rebirth to a growing community of followers. As he lay dying, the 80-year-old teacher was surrounded by disciples, many of them crying. Gautama was by no account a sentimental man, and several times he told the monks to cut it…

Lejonklou Entity phono preamplifier Page 2

My first encounter with the Entity was underwhelming. It arrived in a box Amazon might use to ship two bottles of multivitamins; inside the box, I found a rather featureless, black, sheet-metal box about the size of six chocolate brownies arranged end to end in two layers, weighing about 2lb. The front panel contained only the company logo. The back had two sets of RCA jacks, a ground lug, and a pair of three-way switches for setting cartridge loading, with options for 90, 120, and 180 ohms. Unusually, the power cord is captive: Lejonklou believes that in the context of his circuit, his…

Lejonklou Entity phono preamplifier Measurements

Sidebar 3: Measurements

I measured Lejonklou's Entity phono preamplifier with my Audio Precision SYS2722 system. The single, moving coil–compatible input preserved absolute polarity and offered 70.2dB of gain. (Though this is slightly lower than the specified 71dB, my measurement was affected by the voltage-divider action between the preamp's input impedance and the Audio Precision's output impedance of 20 ohms.) The input impedance was 90 ohms with it set to "90," 120 ohms with it set to "120," and 180 ohms with it set to "180," all values consistent from 20Hz to 20kHz. The output…

Technics SU-G700M2 integrated amplifier

When I reviewed Technics's SU-R1000 integrated amplifier for the December 2021 issue, I found its performance beyond my expectations. It practically rewrote the ritual of listening to music on my home hi-fi. With its wealth of technological advancements, significant user options, and clear, three-dimensional sound, it cast a large sonic shadow over the other integrated amplifiers in my possession.

What's more, joined to my reference system, the SU-R1000 upended my preconceived notions of what switching amplification sounds like and enlightened me about the sonic possibilities of those…

Technics SU-G700M2 integrated amplifier Page 2

The G700M2 imbued files with a sense of warmth, but it wasn't overly colored. The G700M2's occasional sins were forgivable. Occasionally, I heard a slight, processed-sounding, oversaturated sheen. Not once did it jab my skull with aggressive treble or fail to deliver deep bass in round, convincing measure. It paired well with my DeVore Fidelity O/96 loudspeakers, bringing out their inherent richness and musicality without laying on the creamy fat with too heavy a scoop. And it was plenty powerful, from the most belligerent rock to the most dynamic large-scale classical.

As I…
