Headphone Amp with optical input

[Tatertots]

Looking for a good recommendation for a headphone amp w/clean sound to run Senn HD650's utilizing my optical out from mobo. I use the pc for gaming and currently have an Astro Mixamp TR and it is way to noisy even utilizing the optical input from the mobo.
