I always had my best one on my integrated amp until recently, I moved my Swisscables Diamond power cord to my Jay's Audio CDT MKIII transport and it made a substantial improvement in SQ. I will have an equally good power cord from Silnote Audio going to my dac also. I have an Audio Envy mega3 on my integrated now and am quite pleased with the results. In truth everyone needs to try different things in their own systems to really know for sure what works best for them though.
