Phono Accessory Reviews

LAST (Liquid Archival Sound Treatment) is a record treatment developed by one Dr. Catalano, which promises to retard dramatically the wear of vinyl discs. I don't feel that the advent of true digital discs will diminish the importance of LAST; on the contrary, as this century comes to a close many stereo records will be in their 30s and 40s and in need of as much preservation as possible, if the sounds and performances we treasure are to be preserved.

In an oft-viewed clip on YouTube, recorded at the 2009 Grey Fox Bluegrass Festival, three world-class guitarists pause during a music workshop to talk about their instruments: Danny Knicely describes his 1939 Martin D-18, Chris Eldridge talks briefly about his own 1937 Martin D-28, and Josh Williams notes that his guitar was made in 2002, by the Kentucky-based luthier Neil Kendrick. Then, with fine comic timing, Knicely remarks, "One of these days, me and Chris will be able to afford a new guitar, too!"

This is a story about a $1375 commercial turntable accessory and a free tweak—the latter discovered while installing the former, although the two things exist quite independently of one another.

Here's how it all went down: Earlier this year, I was sent a review sample of a perfectionist-quality platter bearing called the Buddha Bearing, intended for Garrard 301 and 401 turntables. I was happy to receive such an interesting product but slow in trying it, partly because my record player sounded so good at the time that I didn't want to go tearing it all apart, and partly because there were other review samples in line ahead of the Buddha Bearing.

The 78rpm train has been derailed for the time being. The KAB Souvenir VSP Mk.II phono preamplifier, which I intended to review in this space, has yet to arrive from its manufacturer, owing to a delay in the availability of certain parts. The Elberg MD12 Mk.III preamp has yet to arrive from its manufacturer, owing to a recent redesign. The Sentec EQ-10 preamp is here but has a broken switch I haven't got around to fixing. The McIntosh C-8 preamp, a lovely vintage piece that's available for peanuts on the used market, is still undergoing renovation by someone who isn't me.

Stuff that works, stuff that holds up/
The kind of stuff you don't hang on the wall/
Stuff that's real, stuff you feel/
The kind of stuff you reach for when you fall.

As long as you're spinning an LP for your listening pleasure, and if digitizing it at a resolution of 24-bit/192kHz is transparent to the analog source, why not record and store the LP on your computer at that high sampling rate for future convenient playback via iTunes or for iPod use, or for burning to CD-R? And, while you're at it, why not record the LP unequalized and apply the RIAA curve in the digital domain, where you're not dependent on capacitors and resistors that are imprecise to begin with, and can drift over time? With no drift of phase or value, the virtual filter's results should be better than with any analog filter. And in the digital domain, you can program in any curve known, and select it at the click of a mouse. Aside from the sweat equity invested in programming it in the first place, it wouldn't add a penny to the program's cost.

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 gap—that 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.
