homegrown audio super silver i.c.

hey folks. I have been building a system over the past year that consists of; vandersteen 2ci, parasound cdc1500, parasound dac1000, audible illusions 2d, b&k ex442, tributaries silver biwire and a single run of straightwire (not yet burned in) laser link 2 for the digital coaxial dac connection. i have a very small listening room (approx. 11x11). i started with an adcom 5400. it was too bright and digital sounding for my taste. i liked the sound of the b&k, but in my system the soundstage was shallow. i had hoped to improve the sound with the dac and a set of the super silver ic's. i put a 1m set of the super's in b/w the pre-amp and amp. it's bright again like the adcom. it got even brighter still by adding the dac. the soundstage and decay, blah, blah, blah sounds great, but an s with a female vocalist sounds like a snake. i was going to get another set of the super silver to replace the no name junk interconnects that i'm using b/w the dac and the pre. but, i'm worried that it'll get even brighter! did i make a misake with the s.s.? will they smooth out with burn in? can anyone give me advice as to what in this price range will sound good without the brightness? should i stick with the homegrown's and maybe get their silver solutions instead of the super? i don't want to lose the increased soundstage, but i also don't want to get fatigued listening. thanks to all for your "sound" advice.
