The DacMagic Plus includes one more adjustable sonic parameter: absolute phase. If a user

holds down the digital filter button for more than a second it becomes the phase switch so you

can go from positive phase to inverted phase. For those who haven’t heard of a phase switch

before, it’s not the same as the phase button found on early stereo gear, which switched one set

of speaker leads on only one channel to compensate for improperly wired speaker cables. The

phase switch on the DacMagic Plus changes the positive and negative leads on both channels so

the absolute phase is reversed. A signal that would have caused a speaker cone to move outward

now will make it move inward.

For audiophiles who want to know exactly what the sampling rate is for every piece of music

they play through their computer’s playback chain, the DacMagic Plus includes a set of blue

LEDs that inform you of the current rate. Since some players and computers will automatically

downsample higher resolution digital streams if not configured properly, these notification LEDs

can be especially useful to make sure that your new 192/24 music file is actually being played

back at 192/24.

As I mentioned earlier, the DacMagic Plus lacks a remote control. Adding a remote is not even

an extra-cost option. If you must have a remote control you are out of luck unless you couple the

DacMagic Plus with an amplifier or powered speaker system that includes its own remote.

SONIC CHARACTER

Some cynics will tell you that the only difference between a $5000 DAC and a $649 DAC is the

size and weight of the cabinet and thickness of the faceplate. The Cambridge Audio DacMagic

Plus is one of the DACs they will probably champion as a prime illustration of their point. It is a

very good DAC, with the kind of performance that will keep many audiophiles content for a

good long time.

And which of the three filter settings will guarantee lasting sonic nirvana? After over a month of

listening I still have no idea which setting is best. For 320 BPS MP3 files I used the steep filter

settings, but with full rez and higher rez music files I vacillated between the linear and minimum

phase settings. While I did hear differences between the two, neither proved to be a consistent

preference. On some recordings linear phase seemed to have better depth recreation, but on

others the minimum phase presented the most cohesive and well-defined soundstage. On my own

recordings I could definitely hear the reduction of high-frequency air with the steep filter, but as

to which of the other two was a better match, it was a toss-up. Let your ears be your guides.

While the DacMagic Plus never failed to deliver good sound, the input source was the most

critical factor in its performance. Its USB 1.1 input was by far the least exciting and most

dynamically constricted source, with a soft veil over the leading transients. Even the Matrix

96/24 USB converter delivered better dynamics and speed. With the USB 2.0 input, sonics were

substantially better, with more dynamic energy, inner detail, and life. The best sound I got from

the DacMagic Plus was when it was connected via S/PDIF to the Empirical Audio Off-Ramp 4

USB-to-S/PDIF converter. The second best sound, which was extremely close to the Off-Ramp,
