    Has anyone compared Pacific to GG yet? Pacific valves are still restricted, the other valves haven't rolled out, so I will be able to valve tune my GG to beat the Pacific.
    Audition recordings: Zero Distortion Link; Reference Components: Zero Distortion Link; Own: Lampi GG One-day-to-get: Apogee Scintilla, or a horn (with Tenor 75 OTL ), Preamp to be fit in to suit the gain and drive the power amp. Analog: TBD

    I gather the vast majority of, if not all, dacs sound better balanced.
    It’s whether single ended is decidedly worse, and loses any performance superiority the dac has.
    How much of a SQ discount there is with RCA compared to XLR, I suspect is quite preamp dependent

    Our experience with Aqua Formula playing through RCA is very limited. Sorry can not be more helpful

    Here is a very nice review of the Formula xHD dac: http://www.hifi-advice.com/blog/revi...rmula-xhd-dac/, some comparison to other DACs, USB vs other inputs, XLR vs RCA.
    I noticed that Formula has a modular input option. The available options for the Modular Input are AES/EBU, RCA, AT&T ST Glass and Optical TOSlink. The reviewed sample had AT&T ST Glass input. Is this an Ethernet input or something else? What source can be used with this input?
    Thanks.

    thank you for the review link. the nicely written review mirrors my views on the Formula dac as a top performer and clear view on the music. too bad not much on the addition of dsd to the performance.

    My thoughts too. I'll probably do it in a few months but would like to know how natively DSD sounds.

    Does anyone know how the Formula decodes DSD since it is a ladder DAC? Does it convert DSD to PCM internally or does it actually have some sort of on board DSD decoder?

    It is my understanding that DSD is converted to PCM internally.

    Ouch, if true, not good.

    Can someone with the xHD upgrade + HQPlayer share what settings you have found to work well with the Formula xHD?

    I emailed Aqua and they confirmed that the Formula does convert DSD to PCM internally. They tried different solutions for DSD playback and determined that the best sounding solution was via DSD to PCM conversion.
