Emotiva ERC-2 CD player Measurements

Sidebar 3: Measurements

I ran the review sample of the Emotiva ERC-2 CD player through my usual test regime. To measure the ERC-2, I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It" for some tests, I also used my vintage Audio Precision System One Dual Domain and the Miller Audio Research Jitter Analyzer.

The maximum output level from both the ERC-2's balanced and single-ended outputs was 2.25V, which is 1dB higher than the CD standard's 2V. If not accounted for, this will tilt A/B comparisons…

Cayin SP-10A Integrated amplifier

Stereophile has reviewed two integrated amplifiers from Chinese manufacturer Cayin in the past: the A-50T, which I wrote about very positively in March 2008, and the A-300B, which Art Dudley reviewed in February 2007. So when I read about Cayin's $2195 SP-10A integrated amplifier, which has a wood-covered sleeve, just like the old Marantz and McIntosh gear and offers 38 watts of push-pull power, in our coverage of the 2008 CES, I put in on my must-write-about list.

When Steve Leung, of importer Valve Audio System (VAS) Industries, commissioned the design and manufacture of the SP-10A, he…

Cayin SP-10A Integrated amplifier Measurements

Sidebar 3: Measurements

I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see the January 2008 "As We See It" and www.ap.com) to measure the Cayin SP-10A amplifier. Because some of the measurements produced anomalous results, I repeated some of the tests with our Audio Precision System One.

With its volume control set to its maximum, the Cayin's voltage gain from its 8 ohm tap was lower than the norm for an integrated amplifier—30.7dB into 8 ohms—and even lower from its 4 ohm tap: 23.8dB into 8 ohms. This won't be an issue with CD players,…

Nuojuva: <i>Valot Kaukaa</i>

On Valot Kaukaa, Finnish producer Olli Aarni, working as Nuojuva, creates a strange, romantic world of sound. We hear wind and birdsong; crackle and hiss; hints of familiar classical pieces; cello, flute, and violin; whispers and sighs from Rachel Evans of Motion Sickness of Time Travel; and the lovely piano work of Sophie Hutchings, whose 2010 album, Becalmed, was one of my 2011 “Records to Die For.”

The sounds here are gentle, soothing, and soft, rather than aggressive, harsh, and angular. Something about these sounds seems to look into the past, as if turning pages in a photo album or…

Stenheim Alumine loudspeaker

The sound of the Stenheim Alumine loudspeaker—its openness, transparency, and freedom from temporal distortions, not to mention its good bass extension for such a small enclosure—reminded me at once of my favorite small loudspeaker from the late 1980s, the Acoustic Energy AE1. On reflection, the comparison is extraordinary: The two products are as different as night and day, the AE1 being a wooden loudspeaker with a metal-cone woofer, the Alumine a metal loudspeaker with a pulp-cone woofer. I suppose one can skin a catfish by moving the knife or by moving the fish.

Yet from there,…

Stenheim Alumine loudspeaker Page 2

It was easy to find places at which the Stenheims performed well—my review samples wound up about 5' from the wall behind them and a little less than 2' from their respective side walls—but getting them to "disappear" required a bit more trial and error with regard to toe-in angle and distance from the listening area. Ultimately, I wound up aiming the cabinets directly at a single, centered listener, with the listening seat closer to the speakers than is the case with my Audio Note AN-Es, which I place against the front wall.
