> is it a maximum of 192 kbps as I have heard mentioned?

The *signal* rate (bits/second) of USB is far better than what's needed for the *encoding* rate (bits/second) of the audio files/streams, especially USB2 which can do 480 Mbps. The *sample* rate (samples/second) of a DAC is multiplied by the bits/sample and number of channels--usually two--of the inputs to get the number of bits/second needed to feed it at the rate for highest quality. For CD audio, this is 1.411 Mbps, which is even achievable by USB1.


> but has lower sound quality, probably due to being a cheaper bit of hardware

Even a "cheap" DAC can do 192 KHz at 24 bits/sample but needs 9.2 Mbps to do that at highest quality.

Mainly what determines sound quality is the weakest component, of course. The analog stage electrical isolation (especially from the power source) tends to have the biggest impact these days, because fewer discrete components are needed in capable designs. A battery-operated device can achieve that isolation very easily. The digital bus (USB, I2S, SPDIF, etc.) can generally be considered equivalent to an audio noise wall, even with relatively cheap cables connecting the system nodes.

Now, the perceptual encoding of Adagio+ is below even the "encoding" rate of CD audio, but it's unlikely you will be able to hear much of a difference between that and a CD. OTOH, if your system--including your ears--can distinguish between CD and SACD rates, then you may need to invest more in a better DAC.
