I examined the Bryston BCD-1's measured behavior mainly using Audio Precision's top-model SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue), as well as, for some tests, our Audio Precision System One and the Miller Audio Research Jitter Analyzer. As always, I experimented with the grounding between the player being tested and the test set to give the lowest level of measured hum.
The BCD-1's error correction was excellent; the player suffered no dropouts until the gaps in the data spiral on the Pierre Verany Test CD reached 1.5mm…
Unless you've already acquired a large collection of SACDs, buying a player in 2009 necessitates an act of faith similar to the one turntable buyers faced back in 1992. As with the LP back then, the major labels today have all but abandoned the SACD to such niche players as Chesky, Proprius, Harmonia Mundi, Pentatone, Channel Classics, 2L, Telarc, Mobile Fidelity Sound Lab, Groove Note, and Acoustic Sounds.
Meanwhile, at least for the time being, major labels—even Sony—have gotten back into vinyl in a big way; between them and the independent and reissue labels, there are now…
The choice of filters was less important with bright, hard-sounding CDs, of which there are too many; like a warm-sounding phono cartridge, the Marantz could make a silk purse of a sow's ear, and did so with many CDs, particularly recent reissues of vintage pop recordings.
Against the Cary 306
After I'd been happily listening for a few months to the SA-11S2's warm, detailed, emotionally involving sound, John Atkinson sent along Cary Audio Design's CD 306 Professional Version SACD player ($8000) that he had reviewed in November 2008 (Vol.31 No.11). He suggested I use it as a…

The Marantz SA-11S2 Reference was assessed using Audio Precision's SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue), as well as, for some tests, our Audio Precision System One and Miller Audio Research Jitter Analyzer.
The Marantz's maximum output level at 1kHz varied according to whether CD or SACD was playing and which of the three filters had been selected. The level from the balanced XLR jacks was 4.4V with SACD and Filter 1 and 2, increasing to 5.23V with Filter 3. With CD, the maximum balanced level was 4.8V with Filter 1…
Determining whether an idea is brilliant or off the wall is often a matter of perspective—and of looking at the results that follow from the idea. Take the notion of AC regeneration. AC is what comes from the wall socket, courtesy a network of power-generation plants, and it's specified as having a certain voltage and frequency, with the amount of current limited by fuses or circuit breakers in the electrical panel of the house or apartment. Audio components—other than those powered by batteries—are designed to convert this alternating current (AC) to direct current (DC), then produce…
One of the most impressive things about the Premier is its ability to reduce harmonic distortion in the incoming AC. At various consumer-electronics shows, PS Audio had earlier demonstrated this effect of the Power Plant design by using a Fluke power-quality analyzer. With the Premier, they've included a built-in harmonic-distortion meter; you can switch the front-panel display to show the THD of the incoming AC and of the output. In my situation, the input THD was in the region of 3–4%, the output around 0.3%.
The Premier allows a choice between sinewave and MultiWave. However, it's…
