After achieving Serenity and acquiring Knowledge, do we end up in the land of Perfection? The room I visited after Perfection was Connection, which was occupied by Quintessence Audio. So perhaps we can say that Serenity + Knowledge + Perfection produces a Connection to something higher than ourselves, which in this case would be Nirvana. (There's also a Nirvana room.)

There are times when a music critic gets so upended by a recording of well-loved music that their previous plaudits for a different recorded version demands reassessment.

Just as they did last year, Gryphon devoted the large Schaumburg E space to static displays, including the debut of the Gryphon PowerZone PZ3.10 power purifier ($14,000) which has eight Furutech AC sockets and 20A current capacity and is said to utilize Quantum Resonance Technology.

Last year in the large Schaumburg F air-walled room in the Convention Center, Stenheim, VTL, and Nordost put together one of the finest sounding rooms I’ve heard at any show. This year, the sound was again among the best I encountered in the over 40 rooms I auditioned.

Steve Jain and his Fidelity Imports crew presented six rooms at AXPONA, stuffed with debut products from across the world.

"I think both moving coil and moving magnet cartridges are terrible." That's what legendary Canadian audio designer Ed Meitner told me when I asked about the pioneering transimpedance current drive phono stage he created for his Meitner PA6 preamp some 40 years ago.

Meitner has been designing innovative hi-fi gear for the pro and consumer audio markets for more than 50 years, but for most of the last 30, he has been best known for his work with high-resolution digital audio and DSD recording. Despite this focus on digital—and despite that comment about the two leading phono cartridge technologies—deep in his heart, Ed still loves analog and has fond memories of the Kenwood optical cartridges from the 1970s, which I discussed in last month's Spin Doctor column. So when Ed read that a company in Japan called DS Audio was bringing back an improved version of the optical cartridge using modern materials, he contacted designer Tetsuaki Aoyagi to learn more.
