Early last year I bought a Eupen power cable after all the positive things said about it on the Groove forums at the time. My Meridian DAC was definitely improved by it, but on changing to a Teac CD player with a captive lead I wasn't sure what to do with it. For a little while I tried it on my Nait 5, problem was that it robbed it of life, and finally ended up on the back of my REL sub. A year on, and the system has been rather overhauled with the electronics now all being Naim units. From my experience with the Nait, I simply ignored the Eupen, at least until the recent bake off at Julians. Whilst there there was a number of cable changes, and the one to the CD players really did seem to help. So, today I finally got around to trying the 05/04 to power my CD5i. All I can say is "why didn't I try it earlier". My present room and system interaction results in any top end "hash" becoming rather unpleasant and leading to some tracks being quite uncomfortable. I'd tried changing interconnects, moving the speakers around, even hanging duvets behind my seating position, none of which quite cured it. The Eupen managed it in one easy swoop. I can only assume that I have rather noisy mains, as CD has now become lovely and open, non-fatiguing and generally wonderful to listen to. So, thanks for the push chaps!!!
