why do people feel the need to buy expensive cable

System dependent.  If you have great components and sources. You should get quality cabling. It depends on what you like. I have a system that consists of that I have 35k in components and speakers retail.  I have about 7k retail in cabling and power cords.  I’m extremley happy with my system.  Cheap cabling didn’t work for me.  I’m extermley happy and I’m done. All I do is look for music now.  Do what works for you. If you have a system that’s not resolving and transparent then cabling is less of a factor. 

32k system here . $400 in cables . Do what you have to do . 

Anyone hear of a big name system audiophile that did a blind test with Monster cable and his $20k Transparent Audio Opus ? This was done on the AVS forum website . He picked his cables 3 times out of 7 tries . The other 4 he picked the Monster cable .

Well to each his own. I use clarity Cable interconnect and power cords  , atlas mavros speaker cables. One high fidelity power cord. Works fine for me to each his own. 

@calvinj whats the difference in the music when you compared the HFC to Clarity Cable interconnects and power cords?
