This is a quote from a head-fi thread from an industry professional comparing the Mola Mola with the Mustec 005:
Essentially it bests the Tamabaqui in every area. As others in the thread have mentioned, to get the best out of the DAC you need a good Pre-amp, but comparing the MM and 005 using a the HPA4, has made me completely re-evaluate the benchmark, which i thought using the MM was super detailed but a little lacking in life . The depth of soundstage is dramatically improved listening to the musetec, so much detail too but it's the dynamics, speed and weight of presentation which are just something else. Apart from the need of an external amp i'm struggling to find a weakness.
Most of my listening is done and comparison with the Mola Mola were made with... Utopia > HPA4 > 005 > USB > Bricasti M5 > Filter > streaming cable > switch .. Listening to 75% electronica, like four Tet, Autechre, Jeff Mills, Max Cooper 25% anything from leonard cohen to MBV, New Order, Miles Davis, etc, etc.
But i have also evaluated on 2 channel set up shahinian obelisk 2 > AGD Gran Vivace GanTube Mono Blocks > HPA4 > Musetec > i2S AGG > 3D Lab Streamer > Ethernet Filter > Streaming Cable > switch ... listening to all type of music
I know i'm sounding like a love-crazed fanboy, but hey thats exactly how this DAC has made me feel.. bit of shock for 48 year old audiophile cynic
