Back in a days when I was a student and studying comp science got into a group that was HiFi interested. Thats how I bought my first setup. It Was HK620 HK CD player and Infinity 31i speakers. What was missing was a RCA signal cable from CD to amplifier. The cheap thin cable delivered was no good, as usual. We started looking into some hifi magazines and went to a hifi fair in Sweden. There was a lot of stuff back than to look into...it was CD era. We where focusing on cables and came across the guy who saw immediately our focus on RCA signal cables. He told us boys, dont spend money do this instead. He gave us a tip about data coax cable back then used for computer LAN networking RG62 or something 75ohm resistance. Never occurred us to think in that direction. The cable had lowest back then impedance. The purity of copper was very good for back then 30 years ago. And it made sense, from theoretical perspective and laws of physics and purpose of cables design. To transfer bits across distance with as least bit failure as possible. We got onto electro book of orders from a shelf and ordered few meters of that cable and several solid build RCA connectors. We had access to soldering station and build our cable ourselves. On my setup the difference was like a night and day. My Jean Michelle Jarre records and pieces all of sudden had soooo much more sounds in background that I never heard before. One of the guys in the group was ske in order ptical and said that his cable was even better. It was HiFi RCA cable with gold and whatever not in it and back than costed 5K SEK. Which is today in corresponding to Which is about 1000EUR today from pure inflation. Money value is even more today. And of course he had McIntosh pre amp, and McIntosh tube mono stages driving his Martin Logan speakers. If his mother only new what amount of money he spent on music she would invicted him from athic.
So, we took his expensive cable went to HiFi store and owner agreed to let us preform direct switching comparison test on same setup of quite hifi valuable equipment.
There was no difference between these to RCA RG62 coax build cables and his expensive one. To our ears anyway. Poor guy tried to make his investment worth wile. He choose to poker and give a vote to the one that he taught sounded better. And he picked RG62 cable ..to his embarrassment he admitted he wanted his cable to win. It was 50/50 after all. The shop owner we knew well said he knew about it being audiophile himself, and kindly asked not to spread rumor around in order to still sell some cables.
My question is if anybody has a soldering station at home and is villing to perform this test again. I am going to buy RG6 and build my own RCA signals again. Will replace my 40EUR RCAs from shop.
Cheers
