Interconnect RCA Cables between Preamp to Poweramp


Does it matter what kind of RCA cables connect between preamp to poweramp?
I tried it with Andioquest Golden gate and my older cables like XLO Signature 3. They both sound pretty much the same. I wonder if I use a pure solid silver cable will hear a difference?

Anyone heard of zavfino cables from Canada?

I’m looking to upgrade my rca I/C. Read the raves about Teos here. Sounded too good to be true for the price - and it was in my system, My xlo sig 3 are significantly better than the Teo. The Teos were closer to the MIT sl 26 I use in a second system. Just one listener’s experience.
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.
