This particular exemplar came to me via a somewhat circuitous chain:
- Jim Smith podcast email
- Positive Feedback article
- Realization that “hey, he’s a BAAS member” (Alón Sagee)
- Download scanned wisdom (link at end of article)
Read it & enjoy.
The ever-entertaining Priconomics web site has followed up their report on subjectivism in wine tasting with a piece on classical music performances.
The conclusions are surprising, and the author ties them in to the Gladwell book Blink.
Yet another reason to close your eyes for any critical audio analysis. I do, and I have come to believe that it’s an essential practice.
Over 50 BAAS members braved a rare San Francisco heat wave and Elite’s store renovations yesterday to hear some of the best that vinyl and tubes have to offer.
Thanks largely to the efforts of Michael Woods (our host) and Peter Truce (or Analog Czar and organizer), the event was a great success. Thanks also to Allen Perkins (Spiral) and George and Carolyn Counnas (Zesto) for sharing their knowledge and expertise. (As a special treat, Zesto played the prototype of their much-anticipated tube power amp.)
Brass Tactics. Get the 5-track EP here. Cool tunes. Well engineered (if a bit compressed). In 320K MP3 (I didn’t notice).
Live concerts in Saratoga and Oakland – July 20-21.
In addition to being humorous, teaches a bit about overload distortion… – Bob
Celebrating their 40th anniversary, TAS is offering their first issue as a free download (PDF).
Printed in 1973, this was the all-analog age. LPs and tapes ruled, as did the Phase Linear 700 amp. And no advertising (Stereophile had just started accepting dealer ads).
I came late to the genius of Frank Zappa. this video provides another look at his art and his modus operandi. As a small bonus, there’s some cool footage of Dweezel at a mixing board, analyzing and enjoying his father’s master tapes. (Frank owned all of his masters.)
The recordings are analog, but the medium is ink on paper.
This article describes the process used by Indiana University, and contains recordings from the nineteenth century.
The HiFi Shock website fills a unique niche, specializing in showing what’s inside audiophile gear.
Some very interesting images.
New startup idea: do video.
We all lament how difficult our hobby is. How can we capture, remember, and describe an ephemeral audio event? How can we reconcile the results of objective vs subjective testing? Of sighted vs blind testing?
When I’m asked what it’s like to be an audiophile, I usually point to wine-tasting as the closest analog. Both involve fleeting, personal experiences. Both have myths and sciences. And, when in doubt, both favor the subjective view over the objective.
And both suffer from the bugaboo of expectation bias. Take, for example, the following passage from this article in The Atlantic:
An expert’s own expectation can act like Kryptonite on their superpowers. Expectation, as it turns out, is just as important as raw sensation. The build up to an experience can completely change how you interpret the information reaching your brain from your otherwise objective senses. In psychology, true objectivity is pretty much considered to be impossible. Memories, emotions, conditioning, and all sorts of other mental flotsam taint every new experience you gain. In addition to all this, your expectations powerfully influence the final vote in your head over what you believe to be reality.
Sound familiar? Read the article for an interesting and humorous account of enological blind testing.
It’s a shame that good articles like this 11-year-old piece have fallen into the Wayback-machine crypt. But they have.
A key conclusion reached is that not only does DSD suffer imperfections in accuracy, but also in precision. Ergo, it’s unlikely to produce the same waveform twice (due to intense noise modulation).
Of course, these technical imperfections may yield superior sound – especially when compared to 24/96.
I, for one, enjoy the DSD sound qualities (as do most folks that try them).
Q magazine features this article about a 20-year-old’s first experience listening to vinyl – LZ’s “Whole Lotta Love” no less.
Charming and hopeful. Wait until she hears DSD! LOL.

This video contains the most lucid instruction on digital audio theory that I have seen.
The exposition should benefit non-technical folks as much or more than techies, but beginners may want to start here.
…and DSD recording session.
BAAS members climbed into the Belmont hills yesterday to observe a live DSD-based recording session and to sample and audition four representatives from the current generation of DSD-capable DACs. The devices were:
- Playback Designs MPD-5 (link)
- Benchmark DAC2 HGC (link)
- Mytek Stereo 192 DSD DAC (link)
- TEAC UD-501 (link)
Musical selections – some of which were free downloads and available in both DSD and hires PCM – included:
- “Lush Life” and “Freddie” from AJP3 (link)
- Selkye:”Slow Day” from BCR (link)
- Mahler 2/1 from Channel Classics (link)
- Mahler 1/4 from DLN (link)
- Iyer:”Human Nature” from DLN (link)
- Recording from the live session
As to the results of the listening tests, I’ll leave the details to JVS and his report on Audiostream.com. I will say that the most prominent trend was once again sound quality mirroring price. But opinions varied, especially in the second session.
Also, late in the day and at a member’s request, we conducted a brief single-blind listening test. The setup was simple: two 30-sec level-matched excerpts were played on the MPD-5, one hires PCM and one DSD. Pick the DSD track. Consensus a priori was that this task was “easy” and a “waste of time.” The test results suggested otherwise.
Many thanks to Cookie Marenco, Patrick and the Blue Coast team, and Jason McGuire (master of Flamenco guitar). Great job in making this happen.
