    DSD Direct vs non-DSD Direct: Myth or Turth?

    Although ESS are always been sketchy about the internals of their DACs, we can say with confidence that what I have stressed in bold type is not correct. ESS DAC remodulate PCM in sigma-delta for D/A conversion, as almost every modern audio DACs on our planet do for more than 30 years...

    DSD Direct vs non-DSD Direct: Myth or Turth?

    To my understanding, what you referred to as "Direct DSD" is just the possibility built in some digital to analogue converters (DAC) chips based of one particular technique, that of switched capacitor output, to drive said switched capacitor output stage with bitstreams produced externally to...

    When does it make sense to place preamp between components?

    @oOBurrowsOo, The Dynaudio loudspeakers you refer to (although you didn't mentioned the specific model out of the Evoke range) are inefficient to very inefficient loudspeakers, their sensitivity being in the 84 to 88 dB SPL/1 W/1 m depending on the specific model. You didn't specify the size...

    MAGNETAR UDP800 thoughts?

    The Magnetar brand seems to be affiliated to Reavon, which sell less costly universal integrated players/streamers/DACs : https://magnetar-audio.store/fr/ https://reavon.store/fr/ I was once interested in the latter, for I am in search of a true multichannel universal (disc and computer...

    Toslink or digital coaxial volume control

    The most simple way of the world : as already said above by staticV3, the digital signal is attenuated by software computation in the PC before it being outputted via USB. That's it.

    Are you satisfied with your home Audio System?

    They are old Cabasse Catalane 500 from 1997 onward. Previously, I used to use the contemporary Cabasse Iroise SCS (at its time, the fifth version in 3 years of this particular product, which uses the very same speaker units than the Catalane... Despite of that fact, the Catalane have much less...

    To me, this proposals, especially the inclination of the letters to the right, which suggests movement, evokes motoring more than anything related to sound or science.

    SACD with ESS chips. DSD or PCM?

    I agree with SoundsGood64. JRR, I suggest your friend or yourself ask directly Accuphase, if this particular topic about the detail of the inner engineering of this particular player does matter for one of you : https://www.accuphase.com/contact/contact_us.html
