Best Budget RCA cables

@leemaze - I don't know if there is a solid-core 20awg RCA cable.  Best I can tell, the Audioquest cables are all 22awg solid-core.  I have not done a lot of research, but there could be some cables.  For example, the Audio Sensibiilty Signature cables use a combination of 20/22/24 awg solid-core silver, but you are looking at $600 plus for an interconnect.

All my testing has been done from both interconnect and power cables I have built myself.  I have a power cord that uses 6 x 22awg conductors for each leg (making a 14.5 awg cable).  I also have another power cord that uses 3 x 20awg conductors for each leg (15.5 awg power cord).  Even though the 3x20awg cord has 20% less metal conductor, the bass power and slam is so much more.  On the other hand, the 6x22awg power cord has extraordinary amounts of detail and clarity in the mids and highs.  However, it is rather thin because there isn't much bass power.

The Audioquest power cords appear to use 19awg conductors for hot and 21awg for neutral/ground, which is a great balance between low and high detail. 

The Audioquest speaker cable also uses multiple gages.  The rocket 44 uses 17/18/20/21 awg conductors for difference ranges of frequency.

I have used the standard 12awg OFC stranded speaker wire for the longest time.  I recently upgraded to a Neotech NES-3002, which is 9awg that uses all 22awg solid-core conductors.  It is amazing, but I suppose the Audioquest with larger conductors can be very powerful in bass as well.
