Do expensive cables/wires REALLY make a difference

@ Jmcgrogan2, very well said my friend!

No offense intended, I do tend to be passionate about this subject.

Please don't assume though, that because I disagree with you about this topic that I am a newbie.

I have an ever-changing lineup of speakers but my component's include: Hegel h300, Roksan Radius 5MKII, Paradigm Studio Reference 100's, MacBook W/Amarra, variety of acoustic panels and a bass trap or 2, and I recently purchased a used and slightly marked-up pair of Harbeth 7es2's and I've enjoyed listening to live music on vinyl through them so much I am considering selling both of my speakers and get some Harbeth 30.1's

@ Arcticmonkey, Great system!, I bet it sounds really good!, Congrats!

I do not think that all expensive cables/cords make a difference. However, I can attest to Transparent Opus line = very sublime listening!

@ Jafant, very good cables!
