Robert Brook runs a blog called The Broken Record, with a subtitle explaining that the aim of his blog is to serve as:
A GUIDE FOR THE DEDICATED ANALOG AUDIOPHILE
We know of none better, outside of our own humble attempt to enlighten that portion of the audiophile community who love hearing music reproduced with the highest fidelity and are willing to go the extra mile to make that happen.
Here is Robert’s latest posting.
After making some adjustments to the arm, getting it in the ballpark, Robert writes:
I changed records to a Jascha Heifetz violin concerto that I like to use for tonearm settings. As I’ve mentioned in an earlier article, I particularly like using concertos for adjusting tonearms because of the challenge of getting both the soloist and the orchestra to sound their best. When the azimuth is just right, the soloist will sound full and present, while the orchestra behind them will be clear and distinct.
A few more tweaks and it was sounding right. Robert continues:
Now it was my friend’s turn to play some of his records, most of which I’d heard before adding the shim. On “Mediocre Bad Guys,” Jack Johnson’s voice now sounded more natural, and the thwack of the drum stick had lost its annoying glare. Zeppelin’s “D’yer Mak’er” was now rocking the way it should with the drum kit sounding appropriately huge and the cymbals showing plenty of top end sparkle and with a long decay. And on Eagles “Take It Easy” I could now better make out the many instruments in the mix, as well as the backing vocals, which I’d been struggling to hear clearly before.
Here’s the first question that comes to mind: Could this tonearm/cartridge tweaking and testing have been done using these albums instead of the violin concerto recording?
Possbily, maybe even probably, but it would have taken all day, because nobody really knows exactly how these records actually sound. Were they good recordings? Sure. But were these good pressings? Who can say? And we have no business assuming.
Houses of the Holy sounds very different from copy to copy. We’ve played more than fifty of them, easily, and we’ve heard them sound every which way. (One of the first shootouts we struggled to do in the early 2000s was Houses. We had lots of RL pressings, probably about 15 or 20. I had them all cleaned, then, over the course of about three days I listened to a handful of them for a few hours at a time, this being early days and not a regular part of the work we were doing at the time.
The sound was all over the place, and the surfaces were often too noisy to appeal to audiophiles. I gave up. I needed better cleaning technologies, which came along in 2007, and I needed more rigorous testing methodologies. Houses was too tough a nut to crack. We didn’t do our first real shootout for it until many years later, 2010.
If Robert adjusts the arm to get the sound he expects to hear on the copy of Houses his friend owns, not knowing if the copy he is playing is dull, bright, thin, fat, compressed, opaque, edgy, dry, thick, dull up top, recessed, etc., etc., he might end up doing all sorts of mischief with the setup. All his friend’s other records might now sound worse.
The solution to this problem is two-fold.
- You must use classical music recorded without the use of amplification. Violin concertos are indeed wonderful for this purpose. Pop, rock and jazz is rarely meant to recreate the kind of live performance one would hear in a concert hall. Once you have heard a number of classical concerts, you know roughly what a violin sounds like.
- But do you have a good recording to test with? This is the rub. You must buy many such recordings until you find the ones that have the sound of live music. You don’t need to find the best sounding pressings of any given Heifetz record, but if you play enough of them, some of them will be obviously better than others, and those you can probably use until you find others that are even better.
