The WiiM Amp Ultra is available in limited quantities today on Amazon. I don't know if I "need" the benefits of the 100W per channel or the dual TI PA chips over the WiiM Amp Pro. But what would be interesting to me is if the DSP is an upgrade- not that the DSP is bad in the WiiM Amp Pro. I find when I stick to the graphical EQ it does well, but the WiiM Amp Pro has come up with some funky latency adjustments and EQ adjustments that did not sound good when I used them. I don't see any description of a tangible benefit of the Amp Ultra's DSP hardware or software in the product description, but now that it's launched maybe WiiM can comment?
