Review:

+ The Emerald was the next upgrade to the Opal and best copper cable Audioquest made at the time. The main difference is the use of teflon. While subtle, they produce somewhat crisper and more open highs and better soundstage and tighter, more extended bass but still maintain the sweetness of the Opals. They sound similar to the Wireworld Polaris but sweeter and have a larger soundstage.
For this price point, I am very satisfied and think they are a great value. As a matter of fact, I prefer Audioquest"s older cables to their newer line-up.

+ With the AQ emerald first connected on my system, it sounded like I had replaced a more powerful amp on my system, sound faster in every respect, clearer on midhigh.

+ Was the top of the line copper cable by AQ and was actually part of the AudioTruth line. Fast, detailed but warm sounding.

+ By far if you are looking for a great cable with great cost/performance ratio, this is one serius alternative.
