    ST115 PCIe Hi-Fi Sound Card with ES9038Q2M DAC, Optical/Coax & 3.5mm

    • Flagship Converter, Real High-Res Files: An ESS ES9038Q2M digital-to-analog converter handles up to 32-bit/768 kHz PCM and native DSD512 (DoP256), so FLAC, ALAC and DSD libraries play at full resolution. DSD playback requires an ASIO-capable music player.
    • Genuinely Driver-Free: USB Audio Class 2 compliant Windows 10/11, macOS and Linux recognize the card on first boot. No driver disc, no download, no account. Fits any available PCI Express x1 slot, and also works when installed in a longer x4, x8 or x16 slot.
    • Headphone Jack With Its Own Amplifier: PH-OUT is driven by a dedicated MAX97220A headphone amplifier on a 5 V rail, built for 32300 ohm headphones from sensitive in-ear monitors up to 250/300 ohm studio models. The microphone on 4-pole TRRS headsets is not supported; please use a separate microphone.

    A True Line Out, Not a
    Second Headphone Jack: HIFI LINE OUT delivers standard 2 Vrms line level for powered speakers, a stereo receiver or a headphone amplifier, and is designed to drive loads of 10 k or higher. Headphones plugged in here will sound quiet use PH-OUT for headphones. Both jacks are clearly marked on the bracket.
    Optical and Coaxial for Everything Else: Feed a home-theater receiver, active monitors or an external DAC through TOSLINK optical or coaxial S/PDIF (up to 24-bit/192 kHz; DSD and 768 kHz stay on the analog outputs). All four connectors are live at the same time and share one source, so headphones and speakers can stay plugged in no switching in Windows.
