Thank you. I don't disagree with your approach at all. My situation, however, is a bit different. First of all, I live in a rural area with a population of about 2,000 people. Sitting right outside of my house is my local utility company's large isolation transformer and so not surprisingly, I have found my power to be very clean, no matter what time of day. I used to own a Son of Q balanced power supply and I have detailed my experience with it on this thread. Essentially, I didn't find it did much for me that was good and once I removed it and replaced it with a 20A dedicated line using a 50 foot run of inexpensive 10g Romex, my dynamics improved. Earlier this year, I brought in a P5 and a P10 because a dealer insisted I would see improvement and I experienced nothing that was good. Noise floor in my system didn't change at all and I found that while the P10 was less harmful than the P5, even the P10 robbed my system of subtle dynamics. I soon realized that the output impedance of these AC regenerators is not that low and plugged straight into the wall, I found better dynamics, even with small digital devices like my Chord DAVE DAC that consumes barely 20 watts. Regarding my dedicated lines, that is where I found my money best spent. Some people install dedicated circuits to isolate from noise. I chose to install my lines based on Vince Galbo's premise of lowering line resistance:

Over the past few years, I have tried various conditioners from Audience, Synergistic Research, Nordost, PI Audio Group, Akiko, AudioQuest, Bybee, Furutech, and Shunyata and I found that the "in-series" conditioners seemed to rob dynamics while the "in-parallel" conditioners did not although neither really did anything for my components' noise floor. Part of this is due to the very high PSRR of the power supplies I use. The double regulated Paul Hynes SR7, for example, has a line rejection of more than -150dB which is better line rejection than even the latest Shunyata Denali 6000T. I did find one conditioner, however, that resulted in benefit and that is the Shunyata 2000T. This conditioner doesn't offer much conditioning at all (only -15dB of noise reduction) but what it offers is a feature called QR/BB, a patent pending technology that dramatically reduces any sense of dynamic compression without the use of capacitors. They claim that dynamics are actually improved when amplifiers are directly connected to the Denali 2000T compared to when these amplifiers are directly plugged into the wall. I was a skeptic and while I still don't understand how it works, the improvement is very easily hard as soon as you plug in a component, even a DAC. Combined with the patented magnetic conduction technology used in High Fidelity Cables' line of cabling, I have yet to hear a better power solution. Unfortunately, this setup is not inexpensive and so I have spent more on my power infrastructure than any other aspect of my audio system.
