CD Player/Transport Reviews

They say a jack of all trades is the master of none. While this expression is typically used to describe people, it also works for machines that play 5" optical discs.

The Compact Disc was launched in 1982, but the four decades since have seen an alphabet soup of similar-looking shiny discs including major formats like DVD, SACD, DVD-A, and Blu-ray Audio. As each new format arrived, hardware manufacturers scrambled to keep up, developing machines that could play just about any disc you could throw at them (or, rather, insert in them). The result was a bunch of "jack of all trades" disc spinners...

But what if we gave up the notion of universal compatibility and concentrated on building a player dedicated to squeezing the best possible results from the very first, and by far the most common, shiny 5" disc, the good old-fashioned "Red Book" Compact Disc? Would we get better performance?

There's a school of thought that maintains that among all hi-fi components, the D/A converter is easiest to perfect or come close to perfecting. Just make sure that every sample is converted accurately, that there's little rolloff in the audioband, that aliased images are suppressed almost completely, and that background noise is extremely low, and you have a top-quality D/A processor. Use of a high-quality DAC chip is assumed.

The $1200 D-105u, the top of Luxman's CD-player line, is novel in its twin-triode vacuum-tube amplification in the analog output stage. This configuration is said to provide high linearity with low distortion and that hard-to-quantify musicality found in tubed products. In addition, the D-105u incorporates an anti-vibration laser pick-up mechanism and a high-mass magnetic disc clamper, the latter feature said to mass-load the disc center to minimize spindle-motor microvibration, thus improving tracking accuracy for lowest error rate.
