I like the BDR #4 Pyramid Cones they clean up the sound without killing the 150's sound. I use a Purist Aqueous Anniversary PC this was how I felt:
" Put PAD Aqueous Anniversary PC on power supply for LAP-150 Mkll power supply. Initial reaction, improved quality of sound like rolling in NOS tubes, bigger dynamics, less congested more extended presentation of notes, highs and lows resulting in better defined instruments within a more 3D SS."
