Actually, once you buy the AV7005, you will use mostly balanced cables, which are dirt cheap to buy or make; that is one of the major reasons to use it. All balanced cables are totally immune from the problems that plague unbalanced cables and give the snake-oil boys the opening they need to take advantage of the problems that DO exist there.
A quality XLR connector costs less than $4, and AES/ABU broadcast-standard cable costs around one dollar per foot, which results in cheap balanced cabling. Perfect performance every time, with every cable.
Only fools spend large amounts of money on the cable "snake-oil" nonsense. When it comes to unbalanced cables, there are issues due to the inferior electrical nature of unbalanced cables and the way that they interface with the circuits at either end that cause some cables to sound better in some instances some of the time, but that is a very long story. You probably don't have the EE degree needed to comprehend what actually causes all of that to happen.
The fundamental reason that it happens at all is because the unbalanced cable is a disaster from an engineering standpoint. In recording studios, in industrial instrumentation, and in auditoriums and concert halls all over the world, there are NO unbalanced cables in use; never! The only reason they continue to exist in the consumer audio world is because manufacturers of cheap audio equipment have to compete, so they cheap out.
Another Issue, of course, is that if ALL of the connectors on the back of a receiver or AV pre/pro were XLR connectors, it would be so big it would need its own room...lol. That is a problem that will only be solved when the audio industry settles on a smaller standard connector for balanced 3-wire circuits. That ain't gonna happen soon.
All this crap about super-pure copper and silver wire for cables is strictly snake oil and those of us who have been audio hobbyists for many years and have some technical knowledge do not get sucked in by the smoke and mirrors of the snake-oil vendors who want to sell some super-expensive nonsense solution.
Some unbalanced cables DO sound better in SOME cases than others, and that can be demonstrated, but the things that have to be done to minimize the actual problems that are causing that are not super-expensive to fix; you just need some technical know-how and how to approach the problems.
Most audiophiles are not gullible or stupid, so don't be so quick to label everyone with the failings of a few who are sucked in by the snake-oil vendors.
