Earlier in the week, after reading comments by, I think, Henry T, I swapped my Eupens around a bit. I put an 05/2.5 on the amp and an 05/04 on the CD player. I listened to a few tracks but didn't draw any firm conclusions before being distracted by something else. Subsequently forgot all about it. This evening I was listening to some familiar discs and thinking this isn't sounding right. The bass is a bit loose and one-note'ish. The image is a bit 2-dimensional. Vocals are a little recessed. And as for the treble, well cymbols sounded like they were etched in the air (but that would be the Seismic Sink which arrived yesterday ). Then I remembered the Eupens. I put the 05/2.5 back on the CD player and the 05/04 back on the amp. What the f...! Deep powerful clearly defined bass. 3-dimensional image. Vocals back where they belong. No more one-note'ing. Hmmm! Once again we see the system dependence of cables at work. In my case the smaller Eupen is best for the CD player and the bigger Eupen is best for the amp. Chris
