Will new power cords by my answer?


After years of buying, selling and upgrading, I finally feel I have assembled a system that's "this close" to what I'm listening for-but it's still missing something.
What I'm hoping to achieve is the following:
1. More resolution/clarity. Presentation sounds slightly veiled.
2. That elusive tighter bass.

I'm thinking new audiophile power cords-of which I have none, may be the answer.What do you think?

Cary 303 on a Townsend Seizmic Sink
Rogue 66 Magnum w/upgraded Mullards in the line
Odyssey Stratos
Harmonic Tech Pro Silway 11's IC
Nordost Blue Heaven Rev 2"s spkr. cable
All except Stratos plugged into a Monster Cable HTS 3000 conditioner
Snell Type D speakers

As always, thank you posters for your time and feedback!

Gregh,
You never mentioned the manner in which you support and isolate your equipment.I admit to being biased in this area as I am a manufacturer of an isolation device but each and every sonic and musical criteria that you address is highly affected by isolation measures.Power cords will most certainly have a positive effect but unless you have provided your system with good supports, you will still be falling far short of your system's true potential.

Hello Ken

Thanks for responding to my thread. My system is placed on A Target equipment rack which I must admit slightly shakes when I press the play button on the Cary.
My speakers are placed on Vibrapods that sit on mica board.
The rack of course needs to be upgraded.
In regards to isolation devices, I was completely sold on the Townsend seizmic sink when I auditioned it.
Why?
Because I heard a difference when I placed it under my cd player, which at that time was a Marantz 63se.
Yes, I agree with you, isolation devices do make a difference.
Thanks
