Components listed here have been formally reviewed in Stereophile and have been found to be among the best available in each of four or five quality classes. Whether a component is listed in Class A or Class E, we highly recommend its purchase.

Each listing-in alphabetical order within classes-is followed by a brief description of the product's sonic characteristics and a code indicating the Stereophile Volume and Issue in which that product's report appeared. Thus the May 2017 issue is indicated as "Vol.40 No.5."

IsoAcoustics Inc. has its head office in Ontario and its manufacturing facilities in China, and is headed by Dave Morrison, who for 20 years has been involved in designing radio and television studios for the Canadian Broadcasting Corporation. The IsoAcoustics products are the result of this experience. Although relatively new on the consumer-audio market, IsoAcoustics' speaker-isolation products have gained wide acceptance in pro audio; their client list of recording and mastering studios includes Blackbird (Nashville), Mastering Palace (NYC), Flux (NYC), United Recording (LA), the Boston Symphony Orchestra, Skywalker Ranch, and Abbey Road.

Digital audio forever disrupted the way music is recorded, mixed, and mastered—and, to even greater extents, how music is distributed, sold, played, and consumed. Music unmolested by zeros and ones is now nearly extinct.

There's no going back, but what if, in 1983, the Compact Disc had bombed? What if music lovers worldwide had rejected the shiny new digital format because they thought LPs sounded so much better? And what if later attempts at digital formats with higher resolutions also shriveled and died, due to lack of interest by recording engineers and consumers? What if, to this day, music had remained blissfully all-analog?

The late Owsley "Bear" Stanley spent his life raising consciousness. Whether it was mixing up jars of LSD, building his famous Wall of Sound PA system for the Grateful Dead, or supervising the creation of an incredible library of live recordings, Bear Stanley was after a certain purity, a higher level of quality, epiphanies.

Hitting mailboxes, newsstands, and tablets today, the 204-page October Stereophile, offers 36 pages of audio equipment reports and the revised and updated "Recommended Components" listing. Featured on the cover is VPI's Prime Scout record player, reviewed by Art Dudley, who also offers auditions of speakers from Burwell and Wharfedale. Herb Reichert reviews the AMG Giro turntable, John Atkinson report on his time with KEF's Reference 5 loudspeaker, Robert Deutsch lives with PS Audio's Memory Player, and there are reviews of amplifiers from Dan D'Agostino, Rega, and Linear Tube Audio.

The Waiting Room

Semyon Bychkov and the Vienna Philharmonic's splendid recording of Franz Schmidt's Symphony No.2, recently released by Sony in CD and hi-rez formats, is dazzling in its pastoral splendor. The music is lush and liquid, with one gorgeous orchestral effusion after the other.

On his first solo record since 2011's Modern Art, Sweet again returns to what he knows best, short, sweet, guitar-pop originals.
