I have a Mcintosh/B&w system. In mine the ICs and speaker wire made a huge difference as I had cheap cables from my 90's system. I demoed a set of modest cables installing one at a time and could hear improvements each time which helped justify ordering a complete IC/speaker set. With the power cables I tried a cheap pair, heard a small improvement, so I did replaced all but is only a slight difference in my setup. I know nothing about HDMI but would try a cheaper upgrade and see what happens, if you notice any improvements try an even better one.
Which Cables Are of Most Importance?
In a hi-end system, McIntosh, B&W, which cables will give me the most bang for the buck between IC's, speaker, power and HDMI? Which cables are most important and which are least important? Will concentrating my $$ in any one or two cables give me the most bang for the buck?
