Big Will!
People around here dig Blue Jeans Cable for a Cadillac ride for a reasonable price.
I'm too cheap for even those, though. I think last time I bought HDMI cables, I ended up buying like 8 from Meritline or similar. I didn't want ever to have to order any more again, and I haven't. As far as I can tell, they haven't lost a one or a zero yet. Bear in mind that all my sources are no more than a few feet from my receiver. If any of your sources are much farther away, then a higher quality cable might be worthwhile for you. For 10' HDMI cables, though, cheap is just as good as expensive IMHO.
For speaker cable, I'm fine with Amazon Basics 16 gauge and a few of
these banana plugs. But if you'd feel more comfortable with your banana plugs professionally and permanently attached to your speaker cables, give
Blue Jeans Cable a look.
Even though you didn't ask, I'll mention that the last time I was in the market for some RCA cables, I bought some
KabelDirekt from Amazon. I wanted some long LFE -> joint stereo subwoofer cables without needing a Y adapter, and KabelDirekt were the cheapest shielded cables of better-than-disposable quality
in the configuration I wanted that I was able to find. I highly recommend them.
And don't trust customer reviews for high end speaker cables. People hear the improvements they expect to hear, and they want to justify that they weren't morons for spending a fortune on clever marketing.
