I have PSM156 conditioners in three stereos and one home recording studio. I have plenty of experience with the Ultimate PCs and recommend them.
I think Puritan should market to the pro crowd, as the improvements that these units impart in the studio, to me, are far more obvious that in my consumer stereos. Probably, in part to the fact that I am very familiar with the sound of my instruments, especially the Hammond/Leslies (several models and combinations), so degradation due to compromised AC are more obvious there than the difference in someone else's recorded Hammond on LP, CD or streaming.
