Does this star-studded brand lineup from Quintessence Audio Ltd. of Chicago sound familiar? It should, not only because it’s frequently encountered at audio shows and dealers, but also because it consistently earns plaudits as one of my Best Sounding Rooms.

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.
