Thebesis Pontificatus in 2-Channel Home Audio Posted April 14, 2008 Anyone who genuinely gets great sound for minimal expense has not factored in the cost of his time. I don't care how dramatic you think the burn in has been - if you do not have a fixed reference point assume the sound hasn't changed and that you have. Expensive cables can make a difference to the sound but rarely in relation to their cost. The point of diminishing returns is meaningless to an audiophile. You can only stop upgrading when you stop listening to systems and start listening to music - or when the money runs out.
