I want to stay humble and precise, so I just did the old Hermes bypass test... again. I listened to the album "Harp Favorites" by Floraleda Sacchi on Qobuz to test the difference. I find harp recordings to be one of the best ways to test many aspects of sound, including attack, decay, and the whole freq range from very high down to low mid-range and sometimes upper bass. For soundstage, not so much though. Anyway, I re-confirmed that Pontus II by itself outputs a lesser degree of finesse, speed, dynamics, and decay refinement.
I bought the Bricasti M5 new. For a power cord on my Pontus II, I’m using the Acoustic Zen Krakatoa. It has fantastic top end detail, and very fast and thunderous deep bass. However, the mid-bass and mid-range are recessed. When I use an Acoustic Zen Absolute Copper interconnect between my pre and power amp, it totally fills in that freq range with a very pleasing fullness without sacrificing any details. Without having found that synergy, I would have abandoned the Krakatoa. But with it, I’m extremely pleased! None of the power cords on my Pontus II come anywhere as close to the sub-bass extension and speed as the Krakatoa, which is especially revealed by a Rythmik F12G subwoofer + Zavfino power cable.
