This terrific little over-achiever has already garnered a lot of praise here and in the audio press after only about 6 months in production. I am using it to listen to music stored on my PC hard drive at home only and in the following manner:
1. 1. As a USB headphone DAC/amp powering my IEMs (Thinksound MS01). The Mojo performs brilliantly and to use an old cliché I have instantly “acquired a whole new music library” and it really is true. I love to listen to the DSD files I have (some downloads and some PS3 rips of SACD discs) in DSD as opposed to converted to PCM but what impresses the most is the conventional CD ripped to uncompressed WAV. At this point, using the Mojo, I really feel there’s no valid argument for DSD or Hirez. MQA sounds fab too. Highly recommended.
2. 2. As a DAC for my “big rig” (setting output to the fixed level at 3V). One of the issues I have had with my ProAc Response 2.5 speakers is that they are sensitive to phase and I find myself constantly fiddling with in-/out-of-phase switch. I had the KEF LS50 on home trial for a month and they did not seem to suffer from this problem, but were bested by the ProAc’s in other respects (volume, bass, dynamics) so they were returned. Imagine my surprise that with the Chord Mojo playing through the Aux inputs on the preamp, this problem has entirely disappeared! No more phasey-ness, no sweet spot, just music flowing to every corner of the room. Certainly didn’t expect that. Highly recommended.
3. 3. As a DAC for my Beyerdynamic A20 desktop headphone amp (same Mojo setting as above). Now we’re getting into the “angels dancing on the head of a pin” sort of a debate. There is no question that the amp provides additional value in terms of a more immersive listening experience -- stronger dynamics, general tightness of sound, soundstage & imaging -- all probably in part on its own merits and in part from relieving the USB/amp from its amplification chores. But of course there is a certain inconvenience with an extra box, additional cables, etc. Recommended for perfectionists only.
