Little bit "forward" sound - what cables to avoid?

Even close.

I do not use stock tubes - Pope gives me a great, great improvement, but most signification result I got when replaced rectifier tube with metal base Philips Miniwatt, it was not just improvement, but brought my SLP-05 to the next level up.
I am not looking for something to tweak the system, I just want better cables which would not emphasize sight imperfection (I seems to me that vocal sounds too much to my face, but somebody might like it). In that sence I do not think Cardas is step up from my Wireworld.
Oh well, I guess there is no stright answer to my question, and I have to go thru long and costly process to try as many cables as I can.
Thank you very much anyway.
Boris.

My question is not how to fix "forward" sound, it is just a tendency, not a problem. I just want better cables than my mediocre Wireworld, and do not want them to make it a real problem. So, as Rgs92 suggested I might want to exclude Valhalla IC from the list.
Thank you.

Ryder, no offense, but where did you find word "bright" in my post? I described my system as "a little bit forward" sounding, but it is never bright. To me it is completely different characteristics of the sound.
And I am using Gold Eclipse and Eclipse IC.
Thank you.

OK, I'll try.
It's like wall of sound right in front of you, like singer sings right to your face (I exaggerate of course).
Especially clear I feel it with women vocal - Sarah Vaughan, Patricia Barber...
Thank you.
Boris.

Thank you, Tvad.
Once again, I am not looking for a way to fix forward sound, it is not a problem. I just want to get better cables, and asking if there are cables that potentially can make it a real problem. If cables have nothing to do with that - it's fine, or, as Rgs22 said "I did try Nordost Valhalla ICs once, and they were extremely forward", so at least I will not look at them.
Thank you.
Boris.

I guess I did not make myself clear - my fault, sorry.
Anyway thanks everybody for trying to help.
Boris.
