Hello to all enthusiasts…
I have heard discussion about cables and RCA interconnects for years. And I know there are those that swear by a particular brand name interconnect or speaker cable. That’s perfectly fine with me, everyone has their own desires on where they want to spend their money.
The Immediate answer to the question of sounding “warm” would be that I would suggest you look into vacuum tube amplifiers. The “warmth” you are speaking of will be more apparent. Even with my old ears that signature is evident.
With a 35 year electronics career and 12 years of building amplifiers there are some technical differences in cables and that would be “capacitance”. If you wind two insulated wires together and not shorting anywhere along its length there is an apparent measurable capacitance. That capacitance albeit very very low, is the only characteristic that could possibly affect audio. Cable Manufactures try to get that as low as possible mostly in RCA interconnects. When it comes to these large gauge speaker cables the capacitance is almost immeasurable!
So if you can tell the difference between a 50 picofarad or 250 picofarad cables, more power to you!
I buy good components and build all of my own interconnects and I buy a reasonably priced medium gauge speaker cable and put good quality connectors on them. But, then again that’s just me and not all people can build their own.
I think it comes back to the concept of a Maserati sitting in your garage impresses people a lot more than Chevy.
Of course that’s just my opinion! Tubegeek
