This on usb cables

Most of new gear uses asynchronous USB, meaning that the timing (clock) of USB transfers and clock of internal D/A conversion are independent.  Because of that cable should not affect the sound but often it does, because it picks up noise and injects it into the DAC, affecting timing of D/A conversion (jitter=noise).  I would chose well shielded cable without power wires, if your DAC doesn't need it.  Some expensive, exotic USB cables will sound better if you believe they should - nothing wrong with it, if it helps  :)

Do you have any opinions?

There is no shortage of opinion. : )  Is that what you are 'really' looking for, Opinion?  You also qualify on price, despite stating that you are "happy with what [you] have...."

Read up on the various USB threads. Compare different USB cables and at various price points (your system, your ears). Decide for yourself.

Some expensive, exotic USB cables will sound better if you believe they should

["Some"] implies other expensive, exotic USB cables WILL sound better despite belief???  : )

Read: some that you believe should sound better will indeed sound better.
