Comments on Synergistic Research Res. Ref. FX ?

Has anyone out there had the chance to hear the new Synergistic Research cables, namely the Resolution Reference FX speaker cable or IC's?
I purchased the Resolution Reference X2 cables recently. Great sounding from top to bottom. Prefer them to all previous SR cables and also over Nordost Quatro Fils. Never heard the Vahalla (too expensive). I only wished I purchased a longer pair.
