Controversial. The "best" needn't correlate with price, it seems to me as it can be just as much to do with clever design mass-produced. The clever design is as worthy of discussion as 'high end' materials. And the people who are saying that some low cost gear is as functional as so-called high end may be perfectly able to afford anything you can, but they're arguing from principle rather than just trying to annoy you.
I liked the earlier point from Phelonius (I would put Tim but it would seem a bit too familiar on my part as he doesn't know me from Adam, and I don't sign off with my real name) that the apparently common sense analogy between cables and tyres may be less valid than an analogy between cables and car fuel lines. The audio business seems to be based on 'common sense' analogies that don't necessarily hold water :-d. This thread is based on an analogy between audio systems and chains, for example. From these analogies spring the 'common sense' high end requirements of overblown aesthetics, exaggerated size, exaggerated price when none of these may contribute anything to the final performance. Digital audio is almost un-analogizable, being almost from another dimension and beyond most people's comprehension. The idea that a $5 IC (mounted on a board with a few other commodity parts) may produce a quality of output that surpasses a huge tape recorder or massive turntable simply 'does not compute' for most people. The only answer is to mount that very same IC in a huge machined-from-solid enclosure with a 500W linear power supply and charge $10,000 for it. But the act of doing that is not passive - it asserts that the cheaper devices that use the same IC and perform identically are inferior, and implies that the users (rich or not, ultra-intelligent or not) of such devices are experiencing inferior quality and are guilty of philistinism.
Perhaps most importantly it asserts that nothing can ever be entirely democratic even if it comes from another dimension, like digital audio, and must be layered into the 'natural' hierarchy based on money (rather than intelligence) even if no one can actually show that it is justified.
