What makes the biggest difference in sound quality?

I firmly believe the majority of audiophiles (or audiogoners) don’t read the content of the original post before offering their opinions.

i agree, it is amazing to me when people can evidently type, yet they cannot read...

in some ways it is a pointed commentary on many of the ills of our society in the present day - how people talk past each other, never making an effort to understand what is being asked, what is the exact question or concern being expressed

@STEAKster! I was going to respond to your comments, then I saw your OFFENSIVE and 100% IGNORANT username! I am 36 years VEGETARIAN, now VEGAN. I am also a HERMIT because I REFUSE to support our SATANIC SLAUGHTERhouse society. I also KNOW that many of you on this type of forum trend towards NARCISSISM, and DO NOT CARE. I'm also an ex-hockey player who still trains regularly, NOT one of those WIMPY liberal, commie girly-men vegans. I could have chosen to IGNORE this, and kept QUIET, but my CONSCIENCE will not allow that. 

I'm with AC and room as foundation. Of choice Ted gave, power cable>speaker cable>digital/IC> fuse
