I just got mine today! It's my first Koetsu, but I can say that compared to the Benz Micro Ace HO I was using up until now it's far, far better! Straight out of the box I'm hearing details I never heard before on recordings I'm very familiar with (or so I thought). I suppose it should go without saying, but CD can't hold a candle to it. Not sure about SACD though since I haven't heard one yet.
