The right thing at the wrong time is the wrong thing.—Joshua Harris

The sampling theory formulated by Claude Shannon in the late 1940s had a key requirement: The signal to be sampled must be band-limited—that is, it must have an absolute upper-frequency limit. With that single constraint, Shannon's work yields a remarkable result: If you sample at twice that rate—two samples per period for the highest frequency the signal contains—you can reproduce that signal perfectly. Perfectly. That result set the foundation for digital audio, right up to the present. Cue the music.

I've been looking at this all wrong.

My recent informal survey of ca $10,000 CD players has been based on two assumptions: that the people reading those reviews would be looking for their last-ever CD player, and that such a purchase would require Serious Money.

In addition to such things as the best available design and parts, the most luxurious enclosure, and the utmost in reliability, Serious Money is presumed to buy durability of value: Any appliance that costs $10,000 today had damn well better be worth more than nothing in five or ten years.

I am getting near the end of my Munich High End 2018 report and I am already feeling sad for all the rooms with hornspeakers I did not get to experience. What if I missed all the best ones?

The July Stereophile will include my Follow-Up report on the Joseph Audio Pulsar loudspeakers; the same Pulsars Michael Fremer raved about in his full review. Before I submitted the review, Jana Dagdagan and I made a live binaural recording/video to accompany my written report so you, the reader at home, could experience the exact same recordings in the exact same system in the same room I used to evaluate the Pulsars. Today, therefore, I will only tell you that Jeff Joseph's floor-standing, gloss-white Perspective loudspeakers (15,990 Euros/pair) sounded fuller, deeper, bigger, and richer, than the stand-mounted Pulsars I reviewed.

Look at this photo of Cessaro Horn Acoustics' beautiful-in-color 5-way "Zeta" lautsprecher. Can you imagine it sitting in your listening room? I could, and I'd be proud to own it—if only I didn't live in a one-bedroom Brooklyn apartment and write reviews for a living. The Zetas are new, and cost between 320,00 and 460,000 Euros/pair, which—don't laugh—I think seems like a bargain for all the hardware and good sound a buyer would receive.

2018 marks the 100th year of business for Danish cartridge manufacturer Ortofon A/S—the actual birthday is October 9th—so it came as no surprise that Ortofon's head of product development, Leif Johannsen (on the right in the photo above, next to Lou Dorio of the company's American subsidiary, Ortofon Inc.) cooked up three special, limited-edition products to celebrate the milestone: the anachronistic and ostensibly DJ-friendly moving-magnet Concorde Century; the ultra-high-end MC Century; and the cartridge that most appealed to me, the SPU Century (estimated price: €5000).
