JPS Labs Aluminata interconnect, speaker cable, AC cord

Taken together, these unusual interconnect, loudspeaker, and AC cables brought a new measure of spaciousness, scale, smoothness, heretofore unimagined detail, and overall musical ease and naturalness to my music system. And they did it while sounding neither dull nor bright—just right.

I start with that observation not in an effort to be cute, but as a good-natured warning to ill-natured skeptics: Unless you're open to the idea that such a thing is possible, the 2300 words that follow will be little more than nonsense, howsoever differently I intend them.

There's more:…

Weight was more of an issue with the speaker cables than the other Aluminata models: Their stranded termination leads were, of course, significantly more flexible than the rest of the cable; in my system, with the Quad ESLs raised somewhat inelegantly off the floor, the combination of heavy cables and floppy leads made hooking up a clumsier procedure than usual. Those WBT locking bananas weren't just a luxury, they were a necessity—without them, the Aluminata speaker cables disconnected themselves.

During their stay here, the JPS Aluminatas all worked without a hitch. I should also…

Audience Adept Response power conditioner

I can't remember a time when I wasn't concerned about power quality. I grew up around finicky, home-brew ham-radio gear and labs full of instruments, and with both, power-conditioning gear was standard fare. When I moved into high-end audio, it seemed obvious that power quality was important. As a result, I've experimented with a wide range of power-conditioning equipment, from simple ferrite loops to huge isolation transformers, and even exotic laboratory power supplies that could vary the voltage, frequency spectrum, and shape of the AC signal.

So when Audience introduced their…

Bryston B100-DA SST DAC/integrated amplifier

Over the years, I have used and enjoyed in my audio system large, single-purpose components. Each of these chassis has had but one role: preamplifier, amplifier, digital-to-audio converter (DAC), etc. I guess I've been just a little suspicious of products with multiple functions crammed into a single small chassis; I've figured that the designer may have cut a corner that could affect the sound.

Which brings me to the topic of this review, the Bryston B100-DA SST, which is three separate components in one slim chassis: a DAC, a preamplifier, and a 100Wpc power amplifier. (An MM phono…

Returning upstairs, I remotely browsed my laptop's music folders via the Squeezebox until I found the My Music directory and the "Stereophile Music CD Test Program" playlist. During my audition of the B100-DA, I selected various tracks from this playlist from my listening-room chair, using the Squeezebox's handheld remote. I also used the free subscription to Pandora.com supplied with the Squeezebox to set up my own Internet radio station to play Keith Jarrett recordings over my system.

Setup
The B100-DA SST's chassis is slim, and smaller than that of the Bryston 4B-SST power…
