    audio specs help

    so my new amps have balanced inputs and therefore I am able to easily achieve a 4 vrms input from a soundcard. But I am wondering what are the important things to look at when researching them. this is what i am looking at:
    (note...if you have any recommendations for a soundcard (hopefully below $400 please let me know)

    http://www.ramelectronics.net/html/m...phile-192.html

    main outputs

    max output (balanced): +14dBu (3.9 Vrms)
    max output (unbalanced): +8dBu (1.95 Vrms)
    signal to noise ratio: -108dB @ 48kHz (a-weighted)
    dynamic range: 109dB @ 48kHz (a-weighted)
    THD + N: 0.0023%, 1kHz, -1dBFS @ 48kHz
    frequency response: +/-0.1dB, 20Hz to 20kHz @ 48kHz
    +/-0.1dB, 20Hz to 40kHz @ 96kHz
    +/-0.5dB, 20Hz to 80kHz @ 192kHz
    crosstalk: -105dB, 1kHz, channel-to-channel
    impedance (balanced): 300 Ohms
    impedance (unbalanced): 150 Ohms

    here is all the sc's info:
    The Audiophile 192 continues the legacy of M-Audio’s industry-standard Delta audio card line. Building on our Audiophile 2496—one of the world’s most popular audio cards—the Audiophile 192 features high-definition 192kHz sampling rate, digital I/O, balanced analog I/O and an amazing signal-to-noise ratio. The Audiophile 192 represents a new benchmark in audio performance that’s as good as it gets for music production, mastering and critical listening. As with all Delta cards, you get rock-solid drivers and seamless integration with your favorite Mac and PC applications—and even the ability to combine multiple Delta cards in one system*. And since M-Audio is always ahead of the pack, this world-class card is also compliant with PCI 2.2 and 64-bit audio drivers so you’re ready to take advantage of next-generation platforms and software. The Audiophile 192 is the new world-class standard in stereo audio cards.
