Where the interface would come in handy, however, is in problematic listening rooms. In an asymmetric setting, the balance could be tuned with the…

The computer interface is obviously a big advantage for inclusion in a multiroom installation. In a standard system, however, it's probably not a big factor. Once the novelty wears off, I can't imagine anyone preferring to mess with a computer instead of just using the remote. Similarly, listening to different configuration settings and optimizing for a particular system is a nice capability, but I had no quarrels with CAL's default settings.
The superb dynamics were particularly evident on simple, live recordings like Steve Forbert's club disc, Be Here Now on Rolling Tide, an uncanny re-creation of a club performance and feel. With the CAL, Forbert's presence, and the electricity in the air around him, were spooky. I was tempted to go upstairs and down the hall to test the Holiday Inn effect! Another great example was Sister Hazel's live acoustic version of "All for You" from Collector's Edition, the Albuquerque version of the SBR/Salvation Army benefit CD. Just the simple sound of a pick strumming down the strings on an…
Sidebar 1: Just for Fun: A Format Comparison
Like a lot of folks, I've adopted a "wait and see" attitude toward the emerging digital formats. On one hand, I've got a two-turntable, 10,000-LP commitment to analog. On the other hand, I've been mightily impressed by the initial 24/96 releases, and by demos of Meridian's Lossless Packing and Sony's DSD. In between, there are great-sounding CDs and players like the CAL CL-15. Until it gets sorted out, my strategy is to hunker down with my records and reasonably priced CD and DVD players.
As I was listening to the CL-15, I found myself…

Sidebar 4: Measurements
The CL-15 was measured with its options set to the default settings, the condition in which it was auditioned by Brian Damkroger. One exception was the maximum level, which was at the higher option. From the single-ended outputs, the maximum level at 1kHz was 3.08V RMS, 3.75dB higher than the CD standard. As expected, the maximum voltage from the balanced outputs was exactly twice that, at 6.16V. The output impedance was a low 37 ohms from the single-ended jacks, 114 ohms from the balanced. The output polarity was absolute phase-correct from the single-ended…
Think about it for a second: If you could buy a six-disc CD changer that sounded every bit as good and was built just as well as a similarly priced single-disc player, would you be interested?
There are lots of good reasons to consider a CD changer. One that occurred immediately to me was that I work at home a lot, often spending evenings catching up on reading and paperwork. I rarely work to music because deciding what to listen to and changing discs shifts my focus from what I'm doing to the music. A changer might be a perfect solution. Other reasons popped into my head as…
The Arcam functioned perfectly throughout the review period. One disc, multiple discs, Play, Stop, Shuffle...you name it. The only functional flaw I observed was that the channels were reversed at both sets of analog outputs. Other than that, no failures, no glitches. It also scored highly in user-friendliness. Both the front-panel controls and the remote are logically laid out, with all operations completely intuitive.
The Arcam excelled in background music mode, risking failure only in that its sound flirted with being too engaging to remain in the background. Several times during the…
