I use a mix of different cables for interconnect, speaker and digital cables. I have no complaints. The music sounds great
I would say your own results speak for themselves. Different roads do lead to Rome. Same brand cable loom has worked out for many. Use your ears (As you’ve apparently done).
I have used the same manufacturer for my Line stage:amplifiers/speakers (Coincident) to excellent effect. But have two different brands of cables (Ocellia IC/SC and Lavricables power cables). It has worked out very fine for me.
