Music in the Round

HDMI is the invention of the Devil. I grant that the Devil is very smart—he has put on a single cable both hi-rez audio and video, and paid tribute to the gods of industry by incorporating obligatory content protection. However, he has confounded the rest of us by using a connector that, while it relies on friction to maintain physical contact, has so little friction that the cable connector can be easily displaced from or misaligned with the chassis connector. The traditional audiophile predilection for heavy cables is, in this case, actually counterproductive—exerting just a bit of torque on a stiff HDMI cable can be enough to break the connection.

I've been enthusiastically tracking the development of Bel Canto's class-D amplifiers, from their original TriPath-based models to their more recent designs based on Bang & Olufsen's ICEpower modules. With each step, Bel Canto has improved their amps' sound quality and reliability.

Welcome to the wonderful world of firmware and software updates. With almost every audio device now microprocessor-controlled, and the tasks to be performed increasingly complex, it's not surprising that "finished" products leave the factory only to be stymied by reasonable but unpredicted user practices. It's not that we're all becoming beta testers, but we are contributing to the intelligent evolution of product capabilities.

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.

For years, I have espoused the use of the same speakers (except subwoofer) in all positions for multichannel music. To have no speaker in the system contributing a different voice to the choir seems as intuitive as having the room acoustics not color the sound. Of course, this still doesn't guarantee perfect timbral match—positioning and room acoustics usually impose some unique characteristics under all but the most perfect and symmetrical conditions. You can hear tonal imbalances even between the left and right speakers of most two-channel systems simply by switching pink noise between them. On the other hand, there's no reason to superimpose on these unavoidable differences the additional imbalances inevitable with using different speakers in a multichannel array.

Back in October 2001, when Larry Greenhill told us about the Sony TA-P9000ES multichannel preamplifier, it seemed the best thing since sliced bread. This affordable ($700) analog controller had two six-channel inputs, a six-channel bypass input, level controls for all channels, and a stereo bypass input. For those of us just dipping our toes into multichannel, it was welcome. Though no longer manufactured, the Sony is still a unique component, and one highly prized in the second-hand market. The TA-P9000ES was not, however, the answer to all our prayers—made to complement a digital processor, it basically has only two 5.1-channel inputs, if the TA-P9000ES is used independently.
