Good wire
Color: Black, Size: 20-Feet
Seems to be quality wire but it was not what I thought it was. I thought I was ordering 2/0 but it was #2.

Great wire, great price
Size: 100-Foot, Style: 14-Gauge
There is something about this wire that makes me buy it again and again, and makes me feel like it’s a great value! it’s pure copper strands and it feels, looks solid and as good as anything I ever bought for the sound transmission
The cover is thick, but the wire is still flexible. Looks professional and the white looks better than the old school copper look. Getting the protective sleeve off is a bit of challenge but for me it’s worth it. Have a utility knife, wire strippers and if you have weaker hands, a pair of pliers or something to grip it with to remove from covering wires. It’s worth the effort to me as the results feel solid
I use this with my higher end vintage M&K, Sansui, Pioneer, Timeframe, and other amps, speakers and to my ears, it delivers simple, clean sound at a great price. Don’t buy the hype, buy good wire and call it a day. This 14 gauge even works well with clip posts like on my Sansui 9090DB. 👌
Only thing I would do different, buy the 200ft if you are hooking up Atmos or have multiple equipment. This is my third 100ft in as many months, Lol
