    Hot Audio DACs

    Has anyone tried these DACs?

    There are a couple different variations. I'm looking for something to feed my 3sixty.2 processor. The MARK IV looks like a good choice at $140.

    Mark IV Specs

    The DAC on the Mark IV is a Burr Brown PCM2705 (USB and DAC). I'm not sure of the opamp.

    The Hippo HIfi Bloat for comparison uses the PCM2707 chip for USB combined with the PCM1794 DAC, but for $229.

    I'm not sure how much of a difference this will make in sound quality out of the USB port which is 16bit. Both seem to use USB 1.1 from what I can tell.

    I'm new to DAC technology. So I'm learning as I go. Dave at HotAudio has been great in answering my questions.

    Other Mark IV Specs :
    THD+N when driving a 16-W load is 0.03% at 1 kHz
    THD+N when driving a 32-W load is 0.02% at 1 kHz
    THD+N when driving a 10-kW loads is 0.005% at 1 kHz
    Thermal and Short-Circuit Protection
    Sampling Rate: 32, 44.1, 48 kHz
    Has 3.5mm Stereo Headphone Output Jack on front
    Left and Right Gold plated RCA line level outputs to drive power amplifiers, receivers.
    Dimensions: 65mm by 65mm by 30mm ( 2.5 inches by 2.5 inches by 1 inch )
    Weight: Approximately 100 grams
    Extremely Low Jitter
    USB 1.1
