Need recommendations for 20' speaker cable


When I first moved in my place years ago, my speakers fired down the long wall in a rectangular room. The speakers were 5 ft out from the front wall and the rear wall was 12 ft behind my listening seat. My amplifier was between the speakers so the standard 10 ft run of cable was sufficient.

Currently the system is turned 90° and as shown in my Virtual System pics, the speakers fire down the short wall with my listening seat directly at the rear wall.

Out of curiosity, I purchased a 100 ft spool of generic speaker cable and moved my speakers to their old location. I knew this would happen but I immediately got more depth, more separation of instruments. More localization of musicians, etc.

I don't want to move my rack so if I keep it this way I'm going to need 20 ft of speaker cables. The fact that I now use monitors and the terminals are 2 ft off of the floor only worsens the situation regarding length.

So, long story long, I'm looking for recommendations on 20 ft speaker cables preferably under $1,000 new or used.

Thanks.

I have a very well broken in pair of Groneberg cables.  They are 22 feet long, cost me $1500.00 for each cable.   I’ll give them away for $150.00 for the pair plus shipping.  They have the Groneberg spades at both ends and were soldered with Groneberg solder.  These were custom made for me.  I used them for 8 years or so.   If interested, send a PM. 
You can buy 20' sets from Blue Jean Cables (Canare 4S11), Kimber (many of them), Audioquest and I'm sure there are others.

I have used all 3 and believe BJC are great for the price and I preferred them to Audioquest Rocket 44.  If you would like to 'audition' Kimber and Audioquest (through Crutchfield) have satisfaction guaranteed return policies.

Get the Duelund 12 gauge wire.  No reason to only consider the cotton version as the Polycast sounds fantastic and costs far less.  It is a tad bit warmer and full bodied than the cotton.  Very close overall.  Here is the link.  A set will cost you $240 for the wire and $65 for these banana connectors which I strongly recommend. Use WBT 4% silver solder.

If you don’t have skills in this area I would be happy to help.  If spades are a must, then these are great for the money but not as neutral sounding as KLEI bananas.

20 feet is not too long a length for 12 gauge wire.  No worries as it will sound great.
