So I have had Code 51 over for a while now and even though I am a bit overwhelmed at the moment (hence the recycling of some pictures), wanted to share some initial thoughts because I am very impressed with this cable.
Build quality is as always with EA very good and it is a strikingly beautiful cable. The titanium parts are very nice. I have quite a soft spot for titanium and so I love seeing a cable with parts like this. The y-split often looks bulky on pictures, but is actually really nice in real life. A little on the bigger side, but very light thanks to the titanium. The plug too has some titanium details, which I think looks superb paired with the carbon. The connectors are the new ConX, which makes Code 51 highly adaptable for use with a large number of IEM connectors. I just have 2-pin and MMCX IEMs, but to be able to switch this easily between those is amazing. I have done it a few times now and everything feels surprisingly solid and easy to use.
I have listened to a few different IEMs with Code 51 now, mainly the Empire Ears Wraith and Phantom, the 64 Audio Tia Trio and the Final A8000. I have a few more IEMs to go, but what I noticed is that Code 51 seems to pair well with everything. The Phantom are warmer, more intimate IEMs and there Code 51 seemed to open them up and increase transparency without introducing any brightness. The A8000 on the other hand are really bright, brutally so if you are more treble sensitive, and yet again Code 51 managed to lift the already insane level of detail of the A8000 to yet another level, while making the treble sound even more ethereal and perfectly smooth. I can be quite treble sensitive and the pairing A8000/Code 51 is still one I greatly enjoy listening to. It is like nothing is hidden with that pairing while at the same time it avoids piercing your ears with brightness. The Trio pair really well… Oh that bass… Excellent extension, great control and the mids feel clean and unaffected by the violence at the low end (sorry, been listening to Slipknot). Treble again has the Tia quality and nothing that could be remotely seen as peaky. Just gorgeous extension.
Then IEMs I have brought in especially to create a true summit-fi pairing for classical music: the Empire Ears Wraith. These have an unfortunate reputation thanks to their paradoxical highly sensitive yet power-hungry nature. I have been driving them with an external amp (Dethonray Honey H1) on high gain and the result is super airy and quite unlike other closed IEMs. They feel almost as spacious as IEMs with pressure relief systems (like ADEL that EE used to offer). This pairing is less warm than with the stock Cleopatra, but I personally prefer it, especially for classical music. Transparency is incredible and tonally it balances very well and very natural.
I think that Code 51 has something neutral about it, but without sacrificing naturalness, a combination that is not easy to achieve. Usually I find that cables add some level of colour or inject brightness, but not Code 51. Code 51 is absolutely there, it extends the stage, extends the bass and treble, provides air, clarity and improves transparency and resolution, yet somehow manages not to put its mark on the sound. There are very few cables I have heard that are like this, even in this price range. Usually I find TOTL cables to add something clinical to the sound, even EA’s own Horus did that in my opinion (read: distant memory) and that is not what I personally prefer. Like some exceptionally niche cables I have tried and couldn’t use because those were an ergonomic nightmare, Code 51 brings something especially natural at the highest level and does it with outstanding ergonomics. In every aspect (e.g. sound, synergy, build quality, ergonomics) I consider Code 51 to be among the very top contenders at this price range.
