Power cable upgrades, or Power conditioner?

Tim Stewart from Sanctuary of Sound if you are trying to get your system to be smoother and sweeter I would recommend either the Shunyata Hydra or find a used Bybee pro somewhere they are no longer made. The Shunyata is better but more expensive. It all starts at the wall. Once you get a good line conditioner then your most important cord is from the wall to the line conditioner. But the wonderful thing about audio is that you can do it all one step at a time. I have nothing against the pS audio but you mention your system as being too fatiguing and I personally do not consider the 300 as a remedy for your situation. Also try putting some cones or even cheaper some 3x3 squares of maple or mdf under the feet of your components, or vibrapods.

I can ditto what Tim is saying about the power cord. I have upgraded cords; not expensive; just better than stock cords (Vansevers 211). They warmed the sound. I just purchased a Blue Circle BC62 which is a definitely a step up. I moved it around the system and it worked by far the best put between the wall and my Vansevers Reference 85 conditioner. I guess in that position it improves every component plugged in the conditioner, not just one, which would be the case if it were plugged from the conditioner into a component.

How about some 75.00 Assulum Cords.
You will spend 300/1k and could do worse.
Do yo have dedicated lines.If you can this is the route to go.

Tim...you did not mention what your system consists of. If you are finding your system to be fatiquing I would suggest you look at your system components and how well they complement each other before looking at power conditioners and cords. While a power conditioner such as the PS Audio 300 may clean up your sound it may do little to alleviate your problem with fatique. The money would be better spent on a different CD player or DAC, which is the most likely component to be at fault. Next I'd look at your speakers and their set up. Your system should sound good with stock power cords provided you are listening to good software (some CDs will have you running from the room no matter what you do). Once you like the sound of your system you may want to try the PS Audio. I would be very cautious about throwing a lot of money at power conditioners, and especially power cords, without first finding components that match synergistically. That's really what this hobby is all about. When it comes to cables there is far too much snake oil in high end audio. To suggest that anyone should have to spend hundreds of dollars on power cables, not to mention hundreds or even thousands on interconnect and speaker cable to get good sound is ludicrous. I don't really agree with Tim Stewart from Sanctuary of Sound that it all starts at the wall. Where it all begins is with your source component and your software. Sure, clean power is a good thing to have, but I guarantee you won't hear anywhere near the difference that the right source component, speaker, or preamp will make. One final note: do not overlook your room acoustics and proper set up of loudspeakers. You may find a set of 3 Argent Room Lenses to make a huge improvement, certainly more than a power conditioner! Good luck and have fun with it.

Hmmm. I am wondering if any power modification is going to fix the issue of fatigueing sound. Generally power conditioners and good cords enhance detail, lower the noise floor and improve dynamic range (or some combination of those, depending on the products). They tend (in my experience) to change issues of sound character like tendancy towards fatigue only with analogue gear, where varying the speed of the turntable slightly affects the sound a lot. You might want to think about changing interconnects or speaker cables first, assuming you don't want to change electronics or speakers. I would suggest something like Cardas Golden Cross cables because, though they are not perfectly neutral, they error on the side of smoothness and warmth, which would help with the fatigue. But, if you do buy some sort of power product and it helps, please post about it.
