Spin the Black Circle… Clean

So, I made the plunge-of-faith into the liquorice abyss by purchasing a pre-loved analogue rig – a hot-rodded modified Michell Engineering Orbe SE packaged with Trans-Fi tangential tonearm and other associated goodies. I own many hundreds of records and, over the years, have sporadically purchased more vinyl while not even owning a turntable (a Garrard and subsequent Pro-Ject were sold many years prior). The turntable acquisition was motivated in part by wishing to review analogue gear. The deal was clenched when the prospect presented itself to review that Japanese gem, the outstanding Shelter Harmony MC cartridge; who would disregard that opportunity? But mostly I’ve held the desire, for some time, to reconnect with the great music that guided my own rite of passage, most of which also marked indelible guideposts along the history of music.

Not surprisingly after so many years in static slumber, all of these unplayed gems – rock, punk, collector-worthy classical and 1980s to early 2000s post-punk alternative music – were DOA utterly unplayable. I’m talking organism-rich eco-systems and evolving species inhabiting grooves. Darwin’s case studies. Densely-spread mould forests immovably adhered, firmly in situ, to rip apart the hardest diamond stylus. Jet-powered ultrasonic machines need not apply… Stuck muck, crud crust.

So what to do? Brutally redact my youth’s legacy? Wander the ether in search of expensive replacements while randomly tumbling into endless rabbit holes and virtual dead ends?

Record cleaning

Enter The Vinyl Record Cleaning Company’s (VRC) ESP system. Not the power-of-the-mind-to move-objects or read thoughts but a possible solution to my filthy mind… oh, sorry, grubby LPs. ESP stands for Easy Spread & Peel and, as I found, is an undeniably effective way of making unplayable vinyl playable again. And as part of a regimented maintenance program, there’s a possible added bonus in terms of an upscale in sonic performance (more on that later). The system has been devised by Australian Stephen Price who is based in the small village of Wentworth Falls in the Blue Mountains of New South Wales, a 90 minute ride from Sydney and, coincidences of all coincidences, a stone’s throw from SoundStage! Australia’s own HQ.

The system has been devised around a cleaning solution – Price’s own concocted cocktail – which is applied across the surface of the record, allowed to dry to a thin skin and subsequently peeled off to reveal vinyl that would seem to be… virginal in its pristineness. To assist in its application, ESP has the option of including a rotating system which allows easier, more uniform application and, via spacers, multiple record stacking in order to batch-clean without an invasive and hostile takeover of the entire household.

The graphs below show what my unplayable yet sublime pressing of Du Pre’s interpretation of Elgar’s Cello Concerto looked like before ESP cleaning and then after one, and a subsequent second, ESP going-over. Graphs don’t lie, do they? That may be so, but for me, it’s all about the practical experience. So thanks Mr Price for ESP’ing my first baker’s dozen.

What a revelation! These are records that would have torn shreds off any stylus, guaranteed, and would have sounded like snap, crackle and pop via a megawatt P.A. system while sending your tweeters into paralysis. Yet, post-ESP, I had quiet beautiful music with no more artefacts than are normally expected with good surface quality in vinyl playback. Astonishing!

As Price told me, “ESP has been measured to bring an 11dB increase in overall signal to noise ratio. It’s a 75 percent improvement in how it sounds to the logarithmic way that humans hear sound and there’s a further 8dB improvement to the peak noise floor which is over 50 percent.” These are raw figures provided by Dave Askew, an audio professional who specialises in audio editing, preservation and restoration, audio forensics and audio sciences (more on this can be read here).

Price went on to say, “Whilst the second clean has been highly effective on removing stubborn pops it has also been delivering quite remarkable sonic improvements. Given that the first clean has removed all the fine sediments that create that annoying crackle, my thinking has turned to considering the impact of the mould release agent present in all record pressings.

“This ultra-thin barrier, repeated on a record, would be a sufficient presence between the stylus and the groove wall to impact the most delicate signal elements and would explain why recordings sound more open and with finer detail after an ESP clean. The second ESP clean’s removal of the mould inhibiting agent – something that no ultrasonic cleaner is able to do – provides further sonic performance improvements.”

Further research is being conducted based on the premise that the second ESP swipe’s removal of the mould release agent, which I’m told is used on all vinyl as part of the record pressing process, may indeed have a measurable and consistently demonstrable influence on sonic performance.

So, post-ESP clean, I platter’ed The Pixies’ Doolittle, Sonic Youth’s Goo, AC/DC’s Back in Black, Holst’s The Planets via Dutoit, Du Pre’s Elgar, of course, and many more. And the verdict? Relative silence with that unmistakeable and oft debated vinyl… pure magic.

VRC’s ESP vinyl cleaning system will be investigated further in a full upcoming SoundStage! Australia review. In the meantime, you can find more details on VRC and ESP here.

Stay clean…
