Integrated amp with USB/firewire for under $300?

[schizoid]

I have a near-field/computer/bedroom setup. I'm looking to get a sub (likely a HSU STF-2) to pair with my Arx A1 bookshelf speakers. But I'd like to upgrade my DAC/amp.

Are there any reasonably priced integrated amps that'll fit the bill? I've been looking for awhile, and I can't really find anything.

Thanks for your help!

For what it's worth, I'm using an olddddddd Pioneer SX-201 as an amp and a Miglia HarmonyAudio HA02 Firewire audio interface as a DAC, hooked up to my Macbook Pro.

By definition, integrated amps do not have any kind of processing, so you aren't likely to find one with USB on it. They also do not typically have a sub pre-out. What is the price range? You are probably going to need to look at a Stereo Receiver like the Onkyo TX-8050.

I have an old Pioneer receiver that still works too
