As suggested here, I replaced all of my stock power cords with entry level Shunyata power cords, and the improvement in the sound of my system is nothing short of astonishing. I have messed around with aftermarket PCs before, and did hear a modest effect, but never had I replaced all the stock PCs in my system at once. So, on the recommendation of the fine fellows at Pro Musica in Chicago, I purchased a Cable Pro Integrity 8 outlet Power Strip. This allowed me to remove the old Monster Cable power stip I was using in my system. Then I purchased a used Shunyata Diomondback PC for the connection from the wall to the power stip and three Shunyata Venom 3 PCs for connecting my tube amp, DAC and SB Touch to the power stip. The improvement in sound was immediately noticed! I can't believe how much smoother the system sounds, with much less "background" noise. It is smoother and more transparent! The improved transparency has also allowed more micro-dynamics to come through.
The skeptic in me says that power cables shouldn't make this much difference, but the results can't be argued with. For around $700 my system has taken a huge step forward.
Thanks to all for the recommendations!
Remember, it's all about the music.
Great to hear that this overhaul was successful for you. My first epiphany came with the power conditioner. I really started out wanting better surge protection following some component upgrades. I went with a PS Audio Quintet awhile back replacing the standard power strip and the reduction in line noise was quite noticable. Gaps between cuts on CDs was spooky quiet, and I have a very quiet listening room.
I like to know the incremental benefit if any with each change so I am just now starting down a similar pc upgrade path. A Pangea AC-9 pc targeted for my amp arrived this morning so I will of course be putting that into play tonight and will begin the break-in process. My hope is that improved current delivery will allow the amp to execute at full potential. My amp manufacturer wants the pc to go straight into a separate wall outlet and on a different circuit if possible, not into a conditioner. His reason is the high current needs of the amp. He suggests that most conditioners in their role of lowering noise also limit the current feed somewhat. I have always powered the amp this way but will be most curious if the new cord makes a difference.
PS audio also suggests that the pc that they provide is just a starter cord and a high current cord would be optimal. Not surprising since they also provide upgraded cords. If the Pangea seems to help the amp I will buy a second AC-9 for the Quintet or perhaps move the Pangea to the Quintet and aim higher for my amp. My amp is a much higher quality piece than the conditioner. After that I'll try some source cord upgrades. I like the idea of either the Pangea AC-14 or the Shunyata Venom 3 for those. I realize all these cords are just the beginning of cord options, but I have always been a value buyer. If I can hear a difference it gives me the proof point I would need to try even more quality at a later date. As I said, I like small steps.
I thought one of the selling points of the Quintet is that it is non current limiting. Let me know as I'm considering a PS Audio Quintet in my audio future.
I have held that belief as well, and that is why I have been considering using the AC-9 with it. Pangea touts the use of the AC-9 for amps and power conditioners. I don't want to restrict the current to it in any way. I believe the stock cord that came with it is likely not optimal in that regard. The AC-9 is not the end all for pcs, but I don't think current flow would be one of its negatives. For amps and conditioners I believe logically that maximizing current flow would be high on the cord's objectives. For source systems you are more concerned with sound improvements a cord might permit.
Same observations (although I've only upgraded my power amp with Shunyata Venom 3). But for only $99, it was a staggering improvement. You're right -- most notably, the sound became more liquid.
Now I'm wondering if I should replace my Nordost power cable on my pre-amp with Shunyata? Would that make any audible difference? (Nordost appears to give vigorous, dynamic, highly resolving sound, but lacks warmth and liquidity of Shunyata)
Also, I'm using a linear PSU to power my SB Touch -- would replacing its stock power cable with Shunyata improve the sound? I'm thinking if the answer to both questions is yes, I stand to make substantial improvements for only a couple of hundred of bucks.
I also agree that of all the audio accessories upgrades, power cables seem to bring most noticeable improvements.
Congrats samoore...I agree with you and as I've posted before...for my system and from my experience the power cable upgrade has the biggest impact than any other type of cable upgrade...and I've some pretty nice cables throughout my system.
I can't believe the difference. Best upgrade dollar for dollar ever. Also tried the pc on my Line 6 guitar amp and it was amazing how much better it sounded.
