Sidebar 3: Measurements
I started testing the sample of the Technics SU-R1000 that KM had auditioned, serial number GJ1001007, with my Audio Precision SYS2722 system (see the January 2008 As We See It). However, while I was performing the small-signal tests, the amplifier turned itself off. The temperature of the black grilles on the amplifier's top panel, which cover the internal heatsinks, was 127.9°F/52.9°C. I wondered if the amplifier had over-heated. According to the manual, "one of the unit's safety devices may have been activated. Press the unit on/off button to the Off position.…
Why am I once again falling down the rabbit hole of alternating current? A while back, I committed to listening to SMc Audio's AC Nexus power conditioner, designed by SMc founder Steve McCormack and distributed by dealer Hi Fi One.
If his name sounds familiar, in the early 1980s Steve McCormack, while at the helm of his first audio company, The Mod Squad, invented the Tiptoe. As far as I know, the Tiptoe was the first conical aftermarket footer for audio components. Everyone else since then has copied it. In an interview in this magazine (footnote 1), McCormack admitted, "To this day no…
The Kuzma 4Point 9 ($3995, footnote 3) is indeed 9" long, with an effective length of 229mm: 212mm from pivot to spindle, plus 17mm of overhang. The headshell's offset angle is 23°, while the arm's effective mass is specified as 13gm. Its total mass is 920gm—which, because it doesn't include the "tower" housing the 11" 4Point's mechanism for adjusting a cartridge's vertical tracking angle (VTA), is less than half that arm's mass of 2050gm. This makes the 4Point 9 more compatible with spring-suspended turntables like the Linn Sondek LP12.
Nonetheless, VTA and stylus rake angle (SRA) are…
In poker, "tells" are subtle physical or verbal actions that give away the strength of players' hands.
I am not a poker player, but I am an audiophile, and I use a variety of "tells" as my prime tools in critical listening. You know my worn-out line: "You can't hear what you're not listening for."
I use tells extensively during speaker placement. I use them most extensively, though, when installing and aligning phono cartridges. In that process, tells are a necessity because achieving the best possible sound depends on knowing when I have achieved the best possible sound.

What's the tell for azimuth? The tonearm designer I mentioned above gave me his. "A good record to test azimuth is [Barbra] Streisand's The Broadway Album (Columbia LP CK 40092): On 'Send In The Clowns,' Barbra's voice ought to come across as well-focused, as should the French horn in the background, with the reverb/hall acoustics even on both sides in terms of high frequency content and decay time."
VTA/SRA
Too many people think setting VTA/ SRA is like a tone control: Up is sharper and brighter, down is darker and duller. But how does one know when that sharper/duller…
In the mid-'60s, modern jazz pivoted. Charlie Parker, the previous era's key revolutionary, had been dead for a decade. "Hard bop," the soul-and-back-beat variant of Parker's bebop, was running out of steam. The Beatles were rocking the world, and jazz would never recover as a branch of "popular music." In response or indifference to these tough transitions, jazz musicians set sail on several experimental paths. In those first few years, the most adventurous voyages were mapped and carved out at Blue Note Records.
Two of the best—and most widely varying—of those ventures have just been…
