Beer is an extremely well-balanced cable that could fill the missing 2% from your setup. Although it's the cheapest from Ego family, Beer is likely the most neutral sounding one among them. Beer would be a perfect choice for those who are looking to upgrade their cables while maintaining the original characters from the sound.
It's very easy to think that copper cables would raise the lows and reduce the highs, though that's not always the case. Beer tends to keep the quantities, colors, and sound signatures stay unaltered, including the default tonality and textures. It reminds me of a sweeter and well-balanced version of the Effect Audio Ares II.
