    100% - I almost always prefer the sound of 'local'

    I've been tinkering with the rockna and the mutec mc3+ with the reference 10 SE 120 from a usb output of pc to mc3+, reclock to external 120 clock, AES output to dac Verses PC - USB dac on local.
    I honestly can't hear a difference so far.

    Interesting, with the pi2aes via i2s local sounds clearly and significantly worse, smoothed over and no microdynamic texture. On the other hand either local or stream from the pi2aes sound significantly better than usb, much more focussed.

    @Clemmaster the description of the two modes is as follows:

    "stream mode will track the input frequency constantly while local mode will adjust the lock only from time to time, using a few stages of memory buffers."

    Also, I'm interested in exactly what difference others hear. My thoughts (copied from earlier the thread) were:

    I had been using Streaming pretty much ever since I got the DAC. I was using exclusively the USB input, so I don’t think the setting matters, since the USB clocks are in the DAC either way (based on my wrong assumption that “Local” meant reclocking with the WD’s internal clock and “Strean” meant no reclocking).

    Now that I started using I2S with the NEO Stream and Coax with à CD transport, i clearly found “Local” to be the preferred setting.

    My Pi2AES is acting up and up until very recently, I never managed to get its I2S output to work. For the short while it worked, I found it very good sounding on Local.
    I guess I can try the Stream setting again with the NEO Stream and see if I notice the same improvement.

    Can you contact me at [email protected] and I can walk you through to see if perhaps the pin out is not proper. Polarity swapping can cause strange artifacts including lower volume and phase mismatch.

    Using what is certainly my worst 'source' I can come up with i.e. Xbox Series X>>hdmi-toslink splitter>>toslink to AES converter>>WD (eek! kek!), I hear zero difference whatsoever. Maybe from the ghetto daisy chain. Haven't hooked up my Bryston cd w/ AESyet, will probably do that next weekk. Debating on a Denafrips Hermes or Gaia in the meantime as a digital hub of sorts, and for the i2s out...

    Okay, so since I seem to have the minority view, I redid the stream vs local again. The system is a bit different from last time I did this: superior software on the Pi2aes (Symphonic mpd), and more resolving interstage caps and pot in the aficionado.

    This time, I can clearly hear that local has greater transient resolution, less phasiness, and a more coherent FR - the low and high freqs sound a bit disjointed on stream by contrast. Stream I think still has this slight extra microdynamic texture but the loss of precision and coherence is palpable. So I'm gonna make like a UK government and switch my allegiance 180 degrees to team local.

    Update: The balanced Slagleformer AVC is in, and it does make a bit of difference-like a light veil has been lifted. I like it a bit more in the chain compared to the heavy digital attenuation I was doing. Though, I have to admit, that the improvement-per-dollar ratio on this piece is low.

    The biggest surprise was finding that I'd much prefer digital attenuation to having the Goldpoint back in the chain. I know it's just some resistors, but everything just sounds more 'right' with just the Wavedream or Wavedream + ic0n 4PRO.

    I wonder if capacitance plays a part? How long is the cable run?
