Interconnect RCA Cables between Preamp to Poweramp

What would you recommend to connect the McIntosh C52 preamp to a tube power amp using RCA?

What about using pure solid silver cable for the connection?  

Does anyone heard of this brand name Zavfino based in Canada?

So from your experience, does it matter using a regular basic rca cables like those cheap audioquest compare to a mid grade cables since this is just a connection from the preamp to poweramp

Where can I order one and try it out ?  Can you send me info please.

@rhljazz,   I just placed the order last night.  They shipped it out today.  Once I get it next week,  I will test it out and report.

I bought "the fusion" silver cable. It is awesome ! Best bang for the buck! Pure solid silver. I have been talking to Raymond at Zavfinousa, he is very responsive. They actually engineer and design some cables for high end company but he can't tell me who they are due to contracts. He said " I wish I could but I am sorry we cannot disclose due to the NDA we signed with those companies. They are well known US and European brands that sell for many times over.
We just want to provide similar if not better (since we designed it) to the general public at a great price (and cutting the middleman) so you get more value/bang for the buck."

So far I am very happy with the quality. This is top notch.
And the fusion comes in a box.
