I have an opinion about the Bel Canto 1.1, it is smooth, very musical, more dynamic than the original with excellent resolution and it is a great product. Haven't heard the EVS. Why are there so many up for sale? Because there were many sold and people are always looking for something better is probably the reason. I sure have no desire to sell mine although no doubt there is better to be had for more money but I haven't heard as good for less. The Bel Canto DAC does music right.
