Sidebar 3: Measurements
To perform the measurements on the Linn Majik DS-I, I mostly 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); for some tests, I also used my vintage Audio Precision System One Dual Domain and the Miller Audio Research Jitter Analyzer. Before I did any testing of the Majik DS-I, I ran it at one-third power into 8 ohms for an hour, which imposes the maximum heat stress on an amplifier with a class-AB output stage. At the end of that time, the chassis was only warm.

Manufacturers' Comment #1
Editor: When Stereophile published the first-ever review of the Klimax DS, in March 2008, it was heralded as "the stuff that dreams are made of"; the only real criticism leveled was that the user interface was "stupid." At the time, we maintained that Linn's unique, open approach to the home network would prove fertile soil for software programmers to plant their own ideas and grow their own interface solutions on whatever platform they chose.
Today, Linn boasts the widest range of networked control solutions on the market for any hi-fi product,…
John Atkinson returned to the Linn Majik DS-I in April 2011
Art Dudley reviewed the Linn Majik DS-I in the March issue and found that, when fed audio data over an Ethernet network, this D/A amplifier "presented a more open, nuanced, explicit, involving, and altogether natural musical experience than any USB-based digital source I've heard."
Strong words! But when I measured the DS-I before dropping it off at Art's place, I couldn't get it to recognize the music server on my home network, and therefore ended up doing all the digital-domain measurements using one of the Linn's…
Manufacturers' Comment #2
Editor: The measurements from the Majik DS-I's S/PDIF-TosLink inputs [offered in the Follow-Up of the DS-I] are at the limit of the test equipment (footnote 1). It is consequently not possible for the same test equipment to demonstrate the superior jitter performance of the Ethernet configuration.
We are able to measure the audio master clock (MCLK) inside the Majik DS-I, and what we find is that the MCLK recovered from the S/PDIF receiver (fig.1) has about eight times the jitter of the MCLK that is used for Ethernet audio (fig.2).

My first trip to a Consumer Electronics Show, in January 2010, was an eye-opener. Not only had I never before seen the phony glories of Las Vegas, it was the first time I'd been to a high-end audio show. Between the offerings on the top floors of the Venetian and T.H.E. Show at the Flamingo, I met some great people and heard some wonderful new products. One of those people was distributor Kevin Deal, and one of those new products was from Mystère. Though I was familiar with the PrimaLuna line that Deal also distributes, Mystère was, well, a mystery. However, after a listen to the Mystère…
The owner's manual is well written and informative. A quick peek under the Mystère's hood revealed a beautifully laid out design. The wiring was well done indeed, and even insulated with silk, I'm told. If this is how China can make audio gear, I don't see how anyone can find fault with it.
"I am here to fix ze problem viz yer pheaun."
After setting up the ia21 and letting it cook for a day or two, I sat down and gave it my first real listen. Something was not right. The sound was grainy and rough, the soundstage was not happening, and the frequency response seemed very lumpy. I…
Listening to Bob Silverman showing Brahms and Schumann who's boss was wonderfully engaging. Through the Mystère ia21 running EL34s, the harmonics of his piano were perfectly aligned with the fundamentals. I could hear how well Bob balanced homophonic chords so that the bass overtones aligned with the reinforcements in the right hand. Each note and melodic line retained its relation to the whole, but also allowed the ear to easily separate it from the rest. Whatever my ear focused on in the music it was able to effortlessly hear—no easy feat! More than this, in the quieter passages I was able…
