Silver IC's for tubed preamp/monoblocks

Thanks Folks! Lots of good thoughts here!
I have balanced AudioQuest and Mapleshade ICs in my main system (SS)and whereas they work great with my Parasound Halo A21/P3 and Marantz SACD, I'm not thrilled by their performance with the tube gear. Then I took my pair of Harmonic Tech/Silver that I use with my MDHT/Paradisea DAC (unbelievable affordable piece of equipment BTW!) and hooked the Kavents, let it run for several hours and when I came back... whoa!
Since this is a second system, I'm keeping the $s down to get some decent silver cables.

So I guess nobody has had any experience with the Guerrilla cables? They seem to make good stuff...

Jax2: Thank you for the Quicksilver reminder. How come I didn't consider them!

Azstereo: I looked e-ticketcables up and at the end, www.audioweb.com says the company is http://www.etechvideo.com/, but they got nothing about ICs.

Hey Listener57, thanks for your post. What are you hooking up with your AAD IC's? Did you compare them to something else?

Listener57: very well put answer, thanks for sharing your experience!

MrTennis:
When you say that

silver cables have a character which one can notice after audition for a period of time

Could you elaborate on what you mean by that "character"?

Later on, I'll post a list of the recommendations you all have given me so far.
