Alexc, I did try the EEL on my transport and dac, when I did that I had to put the SR on the amp, the bass got a little heavy and slower. I prefer the EEL on the amp, it really changes the whole soundstage, ie, deeper, better imaging and increased clarity on the top and especially the bottom end - I know the front end is usually where PC's make the biggest difference so go figure. My preamp power cord is not detachable. I think what I probably need is the EEL on my front end and amp.
