CD Player/Transport Reviews

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).

$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.

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.

Those of our readers who are still anti-CD are going to be offended by what I am about to say. Partly because they do not want it to be true, but mainly because it is. I shall utter the heresy anyway: the Compact Disc is, right now, doing more for the cause of high-end audio than anything that has ever come along before!

There, I've said it. Now I shall explain it.

My primary focus this month was MSB's Analog DAC, but since it needed some software updates, MSB suggested that the easiest way to install them was with their Universal Media Transport plus ($5995). Turned out the updates were easier via my regular Meridian Sooloos system, but since they'd sent me a sample of the UMT+, I hooked it up.
