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