Upgrading

Power cords, Interconnects, then speaker cables is my recommendation.

Try to get a full loom going if you can swing it. (Avoid "Cable Stew" of all different mixed/matched brand names/types. Though I admittedly have a couple of different PC’s in my setup at the current time.)

Used Cables on the ’net are good folks, and I highly recommend them.

Unless cable vendors are intentionally screwing with frequency response requiring another of their cables to fix the other ones, then a full loom is not supportable by any logic.

Ever notice how the cable deniers almost never have their systems listed?

Ever wonder why that is?

@theaudioamp , yes it makes sense.

If you run with the premise that cables DO make a difference (and I can assure you they do in my system. It’s easily demonstrable....), matching manufacturers that take the time to R&D their products and design them to work well with each other makes perfect sense.

If you don’t agree, fine, but there’s a reason companies have different levels of cables. And it’s not necessarily because the more expensive ones are prettier. It’s because they work well and sound good together. 

Happy listening!

No I did not notice, because I go on the intelligence of their words. However, now that you mention it, have you ever noticed that cable pushers always have a ton of expensive equipment in a nasty (by acoustical standards) room. I guess they have no money left to spend on what is important?

I also did notice that you did not provide any reasoning why a particular vendors cables would work better with other cables from the same vendor. Your answer was non answer. Please explain in detail, using a written example if possible.

@theaudioamp - I don't think that that it's necessarily expected that the best sound will be the result when using cables from a single manufacturer.  I think it's reasonable to expect that a cable manufacturer would do their R&D with all of their products with the potential benefit of some synergy across their lineup.  Because they are using different components results will vary.  If the manufacturer listens to their products as part of the development process and you believe that cables have a signature sound, it makes sense that you are likely to prefer the same signature sound across your system.

Another way to to say it is that I wouldn't assume that a system with all matching cables will sound better than one that doesn't, but I do think that a listener is likely to reach a pleasing result if they stick with a single company once they determine that they appreciate their signature sound.
