The next time you're preparing to play a record, try doing a little experiment. Once you have the record mounted and spinning but before you lower the stylus into the groove, lower your gaze to just below record level and look for a gap between the platter and the record. It helps if there's a light source or a brightly colored wall behind the platter. You may discover a gapthat very little of the record's playing area is making true contact with the platter mat or (if there is no mat) the platter. Another way to test this is to take a record you don't care much about, put it on the platter, then tap with your finger in the groove area listening for a click as your finger pushes the record down and it contacts the platter surface.
Warps obviously lead to such problems, but even records that appear flat make scant contact with the supporting surface. Turntable and aftermarket accessory designers have recognized this problem for decades.
Over the last 40 years, I have set up or serviced literally thousands of turntables, and during that time I have seen a lot of increasingly sophisticated tools become available to help in getting your turntable optimized. I've had my eye on the Shaknspin speed analyzer since it was launched a couple of years ago, and now there's a new Shaknspin2, which promises more accurate results.
I'm a music lover first, not the most Type A of audiophiles. Sure, I clean my records, but I'm not obsessive about keeping them immaculate like my audiophile father is; he cleans each record ultrasonically before it lands on his turntable platter, writing the date of each record's last bath and which cleaning machine he used on the outside of a fresh plastic inner sleeve before sliding the LP back inside. I don't think his cleaning schedule is rigidhe has far too many LPs for thatbut it's regular. Whenever I visit with LPs in tow, they must pass through the record-cleaning machine (RCM) gauntlet before they're permitted to land on his turntable's platter...
Recently, I tried out one of the many RCMs currently on the market: the redundantly named Nessie Vinylcleaner ProPlus+ ($2495), which despite the name does not hail from Scotland, nor is it a monster; in fact it's smaller than some other record cleaners I've used.
In last month's Gramophone Dreams, I explained why doing any sort of empirical study of high-quality digital sources was extremely difficult. That any success I might achieve as a reporter would boil down to my ability to employ metaphors to describe a DAC's clarity and dynamic personality. Concocting metaphors for DAC reviews is risky because it assumes readers will be familiar with the sound of my amplifier and speakers and, ideally, with one of the DACs I'm using in the comparison. That's a lot to assume.
The stylus that cuts the grooves in your favorite records is best described, in simple terms, as "chisel-shaped." The most accurate playback stylithe "extreme" ones that extract the maximum amount of information from the grooveshave a similar shape, with sharper and more severe contact edges than a standard elliptical stylus, itself an advance over spherical styli.
Let's get right to it: The best way to set azimuth, as I recently wrote in this space, is to measure crosstalk using either a high-quality voltmeter or a digital oscilloscope and a good test record like Analogue Productions' The Ultimate Analogue Test LP (AAPT1). The traditional, qualitative proceduresetting the headshell so that it's parallel to the record surfaceassures only cosmetic satisfaction.
What? Suddenly a new Japanese cartridge manufacturer? That's what I was thinking when Mockingbird Distribution's Phillip Holmes dropped three cartridges on me from DYLP Audio. Never heard of thembut then I'd not heard of MuTech either when Holmes sent me one of that company's $4500 RM-Kanda (now Hyabusa) moving coil cartridges, which I reviewed in the March 2019 issue's Analog Corner. If that cartridge is not on your moving coil radar, you ought to put it there.
Ortofon had hoped to introduce its new MC Verismo phono cartridge "in person" at one of last fall's North American shows, but those shows never took place. COVID necessitated instead an October 30 live Facebook introduction, the company's first such premier. The next day, AnalogPlanet posted an exclusive interview with Leif Johannsen, the cartridge's designer and Ortofon's chief officer of acoustics and technology.
So glad to be back in business with superclean electricity! Especially having spent the last few weeks listening to the remarkably pure-sounding Analog Relax EX1000 cartridge ($16,000).
The brochure asks, "Have you heard of YAKUSUGI Cedar?" No. I had never heard of Analog Relax, either. If you have heard of it, you're at least one step ahead of me.
In the household I grew up in, telling a lie was a death-penalty offenseworse than murder or leaving crumbs on the kitchen counter. So, believe me when I tell you that way more than a year ago, Musical Surroundings' Garth Leerer sent me DS Audio's lowest priced optical cartridge, the DS-E1 ($2750 with energizer/equalizer, footnote 1). He said, "You need to know about this." Then every few months he would write and politely inquire how I was liking it. Each time I would write back saying, "I'm sorry Garth, I haven't tried it yet, but I'll install it right after deadline."
Held every November in normal times, the annual Warsaw Audio Video Show is among the world's largest. I first attended a decade ago, in 2011, and was amazed by both the number of attendeesmore than 10,000 peopleand demographics that skewed young and included many families. That show was bigger and better-attended than any I've been to in America.
Cavitation revolutionized record cleaning more than a decade ago, when Reiner Gläss's Audiodesksysteme introduced its original fully automatic machine. Mr. Gläss's innovative machine, which automatically spun the record in ultrasonically cavitated water, then dried it with fans, at first was plagued with reliability issues, and because it is sealed, it was not easy to repair.
Back in the 1990s, my friend Nick Despotopoulos and I published an article in The Tracking Angle titled "Zen and the Art of Record Cleaning Made Difficult," describing author Michael Wayne's record-cleaning methodology. That regimen, like the article itself, was the most comprehensive one I knew of at the time.
In place of my usual Wilson Alexxes, a pair of small (though very fine) two-way speakers has been in my system this past month: the Marten Oscar Duos I review elsewhere in this issue. Without my usual reference speakers in the system, I didn't feel comfortable covering anything that affects sound quality for this column, so, with the exception of one itemthe firstthis column covers accessories that don't require sonic evaluation.
Ever since I stopped using my Audio Research SP10 preamplifier in the early 1990sits eight phono-stage tubes used to get too noisy too quicklyI tried a variety of standalone phono preamplifiers. Seeing the most service through the 1990s and 2000s were, first, a Mod Squad Phono Drive EPS, then a Linn Linto, both of which I purchased. But when I measured Channel D's Seta Model L, which Michael Fremer reviewed in the August 2010 issue, the Linto was pushed to one side. The battery-powered Seta L (footnote 1) had the lowest noise and distortion I had encountered in a phono preamplifier, and I eventually bought the sample I had been sent for a follow-up review in 2013.
