I don't listen to music when I write, even when I write about listening to music: When there's music playing, it almost always gets my full attention—and I'm no good at multitasking. (And if I'm around music that's awful and I'm powerless to stop it, I have to leave the premises.) A rare exception is when I listen to CDs while proofreading, because proofreading is fairly brainless stuff—and as playback formats go, the Compact Disc isn't the most musically compelling.

The $800 JVC XL-Z1050TN 1050 is the Bitstream successor to JVC's popular 18-bit XL-Z1010, which got an enthusiastic thumbs-up from Robert Harley in April 1990 (Vol.13 No.4). Its styling is, in my opinion, much improved over the older player's, with the distinctive brushed-bronze finish of the rest of JVC's XL-Z line. The rear panel sports fixed and variable outputs (footnote 1), as well as Toslink optical and coaxial digital outputs. As with the 1010, the JVC features their proprietary K2 Interface, a circuit that reduces jitter by resampling the pulses with a short-duration gate just ahead of the single-bit JVC JCE-4501 DAC chip.

I don't know much about horses, but I've been given to understand that dead ones don't respond to even the severest beating. In light of that, I'll make only this brief statement—Even with the best playback gear of my experience, I don't derive as much pleasure from CDs as I do from LPs.—and move on to a simpler truth: Regardless of what I think, CD players are still a necessity for most music-loving audiophiles.

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.

It's easy for reviewers to become jaded by the high prices of some audio products. We get the products in our listening rooms—albeit temporarily—without having to part with our own money. Consequently, we get enthusiastic about products that offer real breakthroughs without, perhaps, fully considering their cost.

Let's go back a few years. Well, more than a few, actually. The electronics end of high-end audio consisted of two companies—Marantz and McIntosh. If you were not up to shopping at their stratospheric price level—even though the industry hadn't yet invented components priced to compete with automobiles—you could always fall back on Dynaco, the poor man's high end in kit form. You hooked all this together with two-dollar connecting cables and 16-gauge zip cord purchased from the local electrical supply house, or—if you felt particularly flush—you'd spend a few (very few) bucks more at Fred's Stereo for the cables with the fancy molded plugs. Hoses were used for watering the lawns.

"In the fields of observation, chance favors only the mind that is prepared."

When Louis Pasteur uttered these words more than a hundred years ago, he must have speculated that they would apply equally well to future circumstances as to the events of his day. What he couldn't anticipate, however, was the technology to which his insight now seems so appropriate.

Publisher's Note: For the first time since I've published Stereophile, we are running two completely different—and opposed— reports on the same product. Normally, we try to reach some conclusion as to why reviewers come up with opposite views on a product, and resolve the problem prior to publication. In this case, the problem lies in the differing sound systems used for review. Since some readers will have systems like SWW's, and others will have systems more like JGH's, I felt it was valuable to run both reviews.

For the record, SWW's reference system consists of Dayton Wright XG-lO speakers, BEL 1001 amplifiers, a Klyne preamp, a SOTA Star Sapphire turntable, the Well-Tempered Arm (or Sumiko Arm), and a Talisman S cartridge. The sound on analog disc is far preferable to that from CD, being much more alive and present, and with a tendency to exaggerate sibilants. The low end of the system is awesome, the high end extended, and transients are rendered with a great feeling of immediacy and quickness.

Can a power-supply upgrade produce audible sonic benefits? If you've upgraded the power supply of a phono preamplifier, you probably don't need to be convinced that it does, and those usually cost only a small percentage of the price of the model they power. But to add Simaudio's Moon Evolution 820S power supply ($8000) to the Moon Evolution 650D DAC–CD transport ($9000), which I reviewed in the November 2011 issue, almost doubles the latter's cost—though the 820S can be used to simultaneously power two Moon Evolution components, like the 750D DAC ($14,000), 740P preamplifier ($9500), and 610LP ($7500) and 810LP phono preamplifier ($13,000).

The CD-200 is the new CD-only player from TASCAM, the professional-audio division of TEAC (footnote 1). It has unbalanced analog outputs, and RCA and optical digital outputs. The CD-200 also has a new transport, the CD-5020A, designed by TEAC for audio use.

Unlike many affordable disc-spinning devices with slot-loading transports (eg, inexpensive DVD players starting at $29.99), the CD-200 has a traditional drawer mechanism that has been upgraded to minimize the noise of loading and clamping a disc. TASCAM also claims improvements in the internal clock function, for smoother sound and lower jitter.

389accu.promo.jpg$13,000! You could buy two Hyundai Excels for that kind of money. Or one 5-liter Ford Mustang. Or two-thirds of a Saab 900 Turbo. How could the purchase of this Accuphase two-box CD player be justified on any rational grounds? What if it did offer state-of-the-art sound quality? Would it really be 50 times better than a humble Magnavox? Would it even be 4.3 times better than the California Audio Labs Tempest II CD player? And would it approach the sound quality routinely offered from LP by the similarly priced Versa Dynamics 2.0 turntable?

The letter we received was innocent enough. It asked for our recommendations on laserdisc combination players. You know, the ones that play all of your optical, laser-read entertainment, from CDs to videodiscs. Had the question been a verbal one, our answer would have begun with a long silence. As it was, we could only jot down a few generic references to features, followed by an admission that we had, collectively, no firsthand experience with these all-purpose devices. Only a few members of our staff have any interest in video stuff—monitors, surround-sound, and the like—among them J. Gordon Holt and yours truly.

Four years after its launch, the CD medium would appear to have come of age, at least in production terms. Annual player manufacture is now big business, and there is hardly a major audio brand without a CD machine to its name—even such analog stalwarts as Audio-Technica and Shure have succumbed.

I once told Larry Archibald it might be worth, say, a 10% loss in sound quality with CD not to have to jump up and turn over the damned record. Sometimes a CD saves you from popping up twice—Mahler's Fifth or Bruckner's Seventh on a single disc instead of three LP sides—or three times—Mozart's Magic Flute on three CDs instead of 6 LP sides. That might be worth a 15% sacrifice.

Audiophiles spend a lot of time thinking about the law of diminishing returns. We'd all agree that spending $1000 to replace an iPhone and generic earbuds with one of Stephen Mejias's "Entry Level" systems is in the early, steep part of the curve: a huge jump in performance for relatively small investment. We'd also agree, or at least suspect, that after you've spent that $1000, the curve gets a lot flatter. What we don't agree on is the shape of the curve between these points. The ideal situation is to find the knee: the point at which the curve's slope changes dramatically. At the knee, we've gotten most of what we want, and the next increment of performance improvement is disproportionally expensive.
