    I've done a lot of research because I have tons of mp3 files on my computer and I want to play them through my vintage McIntosh receiver and the below is about the best thing you can use to do it. The problem is these things are over $200, but the company has been around and making them for a long while and they are about the only converters that will do it correctly. They connect to your USB on your computer to the RCA inputs of your vintage receiver.

    Full Scale Output 2.25 Volts RMS
    Output Impedance 100 Ohm
    Frequency Response (20 Hz/20 kHz) +0db / -.4dB
    Noise Floor (DC to 30 kHz) 4 uV RMS
    S/N Ratio (DC to 30 kHz) 115 dB
    S/N Ratio (A-weighted) 120 dB
    THD+N (1 kHz Full Scale) .002%
    THD+N (1 kHz -20dB) .0001%
    Jitter Contribution (DC to 30 kHz) 135 dB below full scale
    USB to Audio output isolation 200M Ohm
    Sample Rate up to 96 kHz
    Bit Depth up to 24 bit
    USB Transfer Protocol asynchronous
    Power Requirements (USB Buss) 400 mA
    Dimensions 5.6" x 2.3" x .875"

    Then they have a better HD one below with up to 192 kHz sample rates.
