Preamp PC - Elrod Sig II or SR Tesla T2 or ??

I need to improve upon my pc situation at the preamp.

I've heard many good things on the SR T2 tesla line pc.... and have an Elrod Sig III supplying a RSA Haley which in turn feeds the mono blocks, and would also likely feed the Thor line stage preamp.

Any thoughts on these two or another pc for my preamp would be appreciated a lot.

Thanks much
