I have a Metrum Octave that is fed by Empirical OR5/CAPS server. The rest of the system consist of a Thor pre, Pass amp with a mix of acoustic revive interconnects, E.S.P.pcs and MAC Shotgun speaker cables. Recently, I have been switching between Synergistic t2, Triode Wire 10+ and a Electraglide SOTU on the Octave which is very susceptible to pcs. IMO, the SOTU seem to provide excellent synergy with the Octave but others could easily say the same about the 10+ as well, since both have different strengths. As suggested above, best to try a few see what you like.
BTW, Vhiner comments above is right on - give any change a day or two to settle in before any judgment.
