I also have four different brands currently. IMO it's a good idea to start with one inexpensive brand throughout as a baseline then choose one component to try different cables on,usually the source first.
Cable advice
Looking for some opinions on cable mixing. I’ve read that all the cables should be the same brand and same line up to have a more cohesive sound. That does seem to make sense in my head but how important is that? Are you for mixing cables or are you strictly one brand one line and why? What has your experience been?
Thanks
