For my assessment of the performance of the Signature Series II, I chose the 634EARS LOAK2-TX01, one of their flagship trio. It is a single DD iem costing around 835 USD (128000 JPY). The sound profile is v-shaped, with highly transparent mid, lots of energy throughout, and brilliant end-to-end extension. I felt that this is a nice candidate to properly reveal the cables' inherent nature. As a source I used ibasso DX260.
This new Signature Series II differs most obviously from its predecessor in the strand count - whereas the earlier series Ares-S and Cadmus were 4-wire in the standard configuration (with 8-wire released later, Eros-S was already 8-wire), the Ares-S II and Cadmus II comes by default in 8-wire configuration.
First of all, I would like to talk about the ergonomics. While I liked the previous Signature series. I felt that the flexibility of the Ares-S and Cadmus could be improved further. The Eros-S was fine though. Well, looks like EA did read my mind and accordingly improved them. The transparent sheath this time is very pliable and easier to handle, with almost no memory effect. Makes the fit around the ears noticeably more comfortable. Despite the thicker 8 -wire configuration, they are super ergonomic.
The upgraded hardware also looks classier than the previous one. Especially the touch of carbon fiber with matching colour scheme in the splitter elevates the presentation altogether.
Prior to this I was using a 7N UPOCC pure copper cable with the TX01. As soon as I swapped the Ares-S II, I noticed an immediate improvement in the spaciousness of the presentation. The whole soundstage got bigger with more space between notes. I also could hear a subtle improvement in the subbass and midbass heft, but no boominess at all. The midrange and treble notes were largely unaffected. The way it added a slight boost in the lower frequency range whereas not touching the rest is commendable indeed.
When I replaced the Ares -S II with the Cadmus II, I could feel something changed, but it did not become immediately apparent. I had to swap them back 3-4 times to finally apprehend the difference Cadmus II is making to the sound. Simply put, it slightly attenuated the bass heft that Ares S II introduced, and simultaneously enhanced the presence of the upper frequencies. It made the sound slightly more revealing, and a tiny bit brighter in the process. Now, the TX01 is already a very energetic iem, so this effect does not exactly go well with its sound signature, at least for my taste. But I can guess for smoother or a bit darker iems the Cadmus II will do wonders!
I still remember my original impression of the Eros-S. I was a bit puzzled at what it was doing - the note definitions seemed oddly slightly more realistic, nothing seemed overly energised yet the details seemed a bit more prominent. That same effect is present here as well, just more enhanced. It makes the stage bigger, with more separation, and slightly bigger notes, without any over-exaggeration. Very skillfully crafted I must say. Just like it claims, it enhances the overall musicality.
Effect Audio has improved the introductory Signature Series in both the physical presentation and performance to its second generation. Hats off to them for that!
