OP a quality power cord that tends to create a perspective that is more “front row” than “mid-hall”, without being thin or overly bright.
Only power cord that creates that sound is Wavetouch audio power cord. All other PCs’ mid are always far back. Some other PCs have aggressive forward veil/glare noises in front, but not the musical mid-range. Hear WTA PC here https://www.wavetouchaudio.com/reviews.html. WTPC v2 is under $500/5ft. Alex/WTA
