How much power does it deliver?

WiiM rates it at 100W per channel into 4 ohms. Expect roughly half that into 8-ohm speakers, which is still enough for most bookshelf models.

How is it different from the standard WiiM Amp?

The Ultra adds more power, a higher-grade DAC and the Voice Remote 2 with voice input. The standard Amp is smaller and simpler.

Yes. It includes built-in EQ and room correction you set up through the app, which helps tame bass peaks in small rooms.

It handles most 4- and 8-ohm bookshelf and small floorstanding speakers. Very low-sensitivity or hard-to-drive speakers will want more power.

The amplifier and the Voice Remote 2. You supply speaker cables and a source, though streaming is built in.

Not directly. There is no phono stage, so a turntable needs its own preamp or one built in.
