Used cables $1k - SF Amati and Bel Canto RF1000??


I've a $1k budget for used 1m XLR interconnect and 3 or 4m speaker cables.
Currently fighting brightness with temp Supra EFF-I interconnect and Canare 4S11 speaker cables.
Any suggestions for a warm, rich and full sound without losing too much space, air and accuracy?

Thanks, as always...

Tara Labs Quantum interconnects and Tara Labs Space and Time w/TFA Return speaker cables.
I have good luck with my Synergistic Teslas (XLR) between my Pass XP 10 and my Ref1000Mk2. Cardas Golden Ref work well too for me. I think the Teslas give a little more oomph and open the sound up a bit more.
That would be Purist Audio, of course, though $1k might not quite cut it. Some would say Jade Audio too, I guess.
Just want to say that when it comes to balanced IC's be sure to take it real slow. There's a lot more disparity in performance among single-ended IC's than balanced (exactly why I've never found a satisfactory answer). My point is you may be able to find extremely suitable balanced IC's at big savings...the loaner cables available from most of the used cable websites may be worth their weight in gold here.
