CD Player/Transport Reviews

Although the Accuphase DP-75V looks like a conventional single-box CD player, it's actually a separate transport section and digital processor, each of which can be used independently. The transport is a 16-bit/44.1kHz mechanism, the datastream appearing on RCA coax and TosLink optical output connectors on the rear panel.

In 1995, as the compact disc enters its second decade of commercial reality, it's fair to say that the associated hardware has come of age, exorcising at last the digital gremlins of time-base jitter and quantization noise. Digital-processor maturation is particularly evident in the design of the all-critical D/A processor. The simplistic digital circuitry of yesterday has given way to considerable design sophistication that deals directly with jitter and low-level nonlinearities.

Tubes?

In a CD player?

Century-old technology embedded in a modern digital design?

I realize that Aesthetix's Saturn Romulus is not the first disc player or D/A processor with tubes, nor will it be the last—but does combining these technologies even make sense? Are audiophiles working at cross purposes to themselves, looking for modern perfection but preferring a little old-school sweetening here and there?

When a well-respected analog disc-mastering veteran like Stan Ricker says that the Alesis MasterLink ML-9600, a hard-disk-based digital recorder/CD burner, is "the best tool in my mastering bag...done right it can sound better than all but the absolute top drawer analog," you take the endorsement seriously. Progress is possible. Mastering tool, CD burner, 24-bit/96kHz recorder, audio reviewer's best friend—the versatile MasterLink is one of the coolest products I've ever had my hands on.

Recently, we've seen the digital "horsepower" race accelerate with the arrival of digital sources and devices with 24-bit and 96kHz sampling capability. Much of this has been spurred by the 24/96 labels emblazoned on the newer DVD players—and, within the purer confines of the audio community, by high-end DACs with this same ability. Indeed, it's possible that the dCS Elgar DAC, near and dear to John Atkinson's heart and a perennial Class A selection in Stereophile's "Recommended Components," performs so well with standard 16-bit/44.1kHz sources because its wider digital bandwidth permits greater linearity within the more restricted range of regular CDs.

The Arcam Delta 170 is one of the first examples of an entirely new product category: CD transports. The concept of different CD transports having different sonic qualities is vexing. It is a simple matter to prove that the bit stream contains identical data from virtually any CD transport (see "Industry Update," Vol.12 No.8). According to Arcam, development of the Delta 170 was spurred by audible differences among transports heard by dealers, customers, and Arcam staff. The possibility that CD transports have their own sonic signatures is intriguing.
