I ended up getting both the Shunyata Taipan Alpha and HT Pro AC 11 and compared it to my Custom Power Cord Model 11 and this is what I noticed. HT Pro AC 11 seemed to emphasize more middle and upper middle range. I felt low end was lacking, not as balanced or full range sounding compared to the other 2 power cords. Sound wasn't as detailed or quick either. This cable made me appreciate the Custom power cord I had as it was more detailed and neutral. Seemed to be more balanced between highs, mids, lows. The Shunyata was more detailed with faster transients, and smoother sounding with more delicate highs. Sounded more musical and puts me slighty closer to the soundstage. Definately a keeper. Thanks Audphile1 and others for your recommendations.
