Help Need input-Hydra vs New Speaker Cables

Hi:

I am new to Audiogon and would love to hear some advice from anyone regarding my system and what I should add next...

Over the past year, I have started to build my first real audio system. I started with B&W 704s and then added a Lector CDP0 5T CD player and a McIntosh MA 6500 integrated. I am now totally hooked and am trying to find that final 10%.

Right now, I am still using my old Monster Speaker cable and thought about upgrading to Kimber or the Nordost Blue Heaven...While researching cables, I came across many positive reviews on the Shunyata Hydras and the local dealer is now telling me that I will see a very substantial improvement with the Hydra vs a new set of speaker cables. I love the warmth of the McIntosh and Lector but power is always an issue in NYC and the dealer also told me that the Hydra will add substantial clarity to my system.

While I understand the importance of protecting my components, I am really looking to find some additional clarity and soundstage depth. Any input regarding what I should do first or on Hydras would be greatly appreciated...The Hydras seem expensive but based on what my dealer is saying, it sounds like it might be worth it.

Thanks
John
