Room Treatment Reviews

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.

As a film title, Quantizing Hanson Hsu might not rank up there with Kissing Jessica Stein, but we work with what we have to work with. Hanson Hsu is the principal designer at Delta H Design, Inc., an acoustics and architecture firm based in Marina del Rey, California. Though he dabbles in some weird science, Hsu doesn't wear a white lab coat, literal or figurative. He's down-to-earth and personable, with a conversational style that evinces warm wit and a real love of music. At one point in our conversations, he exclaimed, "I get so much joy when things sound good."

In the beginning, I had a room adjacent to my office—a room filled with bicycles, hi-fi gear, and assorted crap I'd never gotten around unpacking since our last move. Feeling ambitious, I thought I might turn it into a guest room, and emptied it.

One of my favorite Charles Rodrigues cartoons, originally published in Stereo Review and reprinted in the book Total Harmonic Distortion (Perfectbound Press, 1988), shows a customer in the soundroom of an audio dealer, auditioning a pair of speakers. This is no ordinary soundroom: the floor, walls, and ceiling are completely covered with irregularly shaped boxes, apparently an extreme form of acoustical treatment. The salesman is saying, "Of course, you realize that it won't sound exactly the same in your living room, sir..."

Recently, I got an e-mail from a colleague at another audio magazine complaining about the paucity of new SACD hardware. We've been hearing about the slowing pace of new SACD releases, and about Sony's neglect of a format they themselves developed, but I now realize that, apart from the High End (footnote 1), machines that can play SACDs have been fast disappearing from the middle of the market. When the battle of SACD vs DVD-Audio was raging, universal players that could play both formats were available from almost every major manufacturer. Even John Atkinson jumped on the bandwagon, acquiring a Pioneer DV-578A universal player for $150 to use as a reference. The exceptions were the very companies that had developed the new formats: Sony offered only SACD players, and Panasonic, at least at first, only DVD-A players. No matter—you could buy a universal player at any national electronics chain store, even if that store didn't stock recordings in either format and their staff had never heard of DVD-As or SACDs. Some things never change.

The acoustic environment for music reproduction is easily the most overlooked source of sonic degradation. Many fine playback systems are compromised by room-induced anomalies that severely color the reproduced sound. When we live in a world of directional wire, high-end AC power cords, and $4000 CD transports, paying attention to the listening room's contribution to the musical experience takes on greater urgency.
