It's the morning of Friday August 3, and I've arrived 30 minutes before dagogo's third annual California Audio Show begins in Burlingame's Crowne Plaza Hotel. In the lobby, the website's founder and show organizer, Constantine Soo, just has time to pose before a map of exhibit rooms on the hotel's first floor.

Bvvvzzzssst.

(Ugh.)

Bvvvzzzssst.

(Where am I? Oh. Bed.)

BVVVZZZSST!

“Alright, alright! I’ll get up!” I yelled at my phone. Slowly, I pulled myself out of bed on an early Saturday morning after a long night out. How did I get home? Something was needed in order to wake me up. Zeppelin’s Presence was on the Rega P1. Perfect.

A recent (unpublished) letter to the editor argued that the reference for audio perfection is the sound of real instruments in a real space. The writer claimed that, since the art and/or science of audio is advancing, and because it is a "scientific truth" that the closer you get to perfection, the less divergence there is components, that therefore there should be less difference in sound among the components listed in Class A of Stereophile's "Recommended Components" than among those in Class B, much less Class C. This should be true of loudspeakers, he said, but even more true of top-rated amplifiers, since "they inherently have less divergence."
