Aune S6 pro / S7 pro combo - fully balanced?

  1. KOALAxT
    Hello head-fi

    I know very little about electrical circuits, balanced vs single-ended topologies etc. so hoping those of you who do know or own the products in question can help me (better) understand. Bear with me here.

    Summary:

    I recently bought an Aune S6 pro, which as I understand it, is not a full balanced dac/amp. This is at least true for the balanced XLR headphone output at the front of the unit. I know this because I reached out to Aune Audio sales directly (Thanks for the quick response, Candy @ Aune Audio).

    My intention was to pair this with the Aune S7/S7 pro amplifier. Aune did confirm this amp as being fully balanced with all the necessary circuitry to make that claim.

    my question(s) for you all is:

    Will pairing the Aune S6 Pro via the independent XLR L/R channels (line out) with the S7 Pro, assuming the S7 does the flipping and decoding of the balanced signal for output via its balanced outs, make this a fully balanced amp/dac combo?

    or

    Is this still considered a single ended signal (topology?) into a balanced output?

    I did follow-up with the same questions for Aune but my concern is that some things may get lost in translation given the language differences.


    Light reading on aune s6 ( non pro) and it's innards

    Hi, thanks for your attention to aune products.

    To answer your quesitons:

    The S6 Pro is balanced and the S7 Pro fully balanced.

    S6 Pro + S7 Pro → amp is fully balanced, while DAC is not fully balanced.

    Oh awesome. Didn't realize Aune was active on Head-fi. Thanks for the response.

    I don't think it matters too much, especially since I am using USB from my pc, but also because I do like the sound signature of the s6 pro w/ the AKM 4497 as is. Furthermore it sounds even better paired with the S7/pro. However, having a fully balanced dac and amp (all in one) would be a a nice touch so I hope you all consider that for the next version.

    Thanks for liking the sound of the S6 Pro and S7 Pro:) And thanks for your advice. We'll pass that to the engineers.

    Hello,
    I bought a S7 pro, and i noticed one thing:
    I connect it with a dac Topping D70 by xlr cable, and then by rca cable, the sound is powerful... I use a HE560 in balanced mode and a 990pro in jack 6.35 !
    And I don't know if my S7pro have a problem but I have to put almost the maximum while with the Cayin IHA6, I'm at 10 o'clok to get the same sound level...
    Is it not normal?
