Ok, here are my preliminary impressions of the M5, somewhat as a comparison to the U18t and Noirte by 64
To begin with, I first spoke to Bogdan when he approached me with an offer to reshell my broken A18t. After a disagreement with 64 I sent them to him, and as we spoke over the repair he told me a lot about his company and product. Normally I prefer companies that have already established themselves in the market and matured, but my conversations with Bogdan gave me a lot of confidence in both the company and their product, so I decided to take that leap
As a stand-alone product, at the price point of 2700USD, the M5 has the most refined sound I’ve heard in the audio industry, hands down. The estat is what I love most about it - it is intense, it is sharp, it is beautiful and it makes me drool every time I listen to a violin. I have never heard Florence + the machine - Stand by me sound as good as it does on the M5. Overall I’d say these are quite neutral, with a hint of brightness. The bass is extremely textured and when necessary can take center stage, but for the most part I haven’t found it to be excessive or key to the presentation of the music. The mids are would be what’s most impressive about the M5, especially female vocals, if it wasn’t for those highs that I keep going back to. The soundstage is big, comparable to the 18, though not quite at the level of the Noir. The two channels are extremely separated and the imaging is excellent - I can tell exactly where each instrument is with deadly precision - i put on an old soul recording and you can clearly hear that the singer is standing up while the piano’s sound is coming from lower below.
The M5 is very coherent, quite possibly the most coherent tribrid I’ve listened to. Nothing from Empire comes close, Jomo sounds like it costs a third of the M5, the Khan sounds great but still nothing close in terms of overall coherency. The Elysium is one of my favourite, but both the lows and the mids work better on the M5
Are they unconditionally better at everything I give them than both the U18t and the Noir? I wouldn’t say so. For one, because both the other two are absolutely excellent IEMs (the Noir is quite controversial but imho a lot of the criticism is unfounded). The U18t performs better than the M5 on purely instrumental jazz tracks, where it’s sharpness gives a really lifelike presentation and makes you feel like you’re then and there listening to the music yourself. The moment you introduce vocals to the equation the M5 takes the lead, but on instruments and instruments alone (see Dave Brubeck - Take Five), the U18t remains my all time favourite
The Noir feels a bit better on rock/trap/hip hop/rap, as it’s bass is somewhat more in quantity and similarly exceptional in quality. It is also smoother than the M5, which once again boosts how good the more modern bassier tracks sound, but makes it fall really far behind the FiR when I give it a live jazz recording, or older, classic rock, where I really crave that unforgiving and sharper nature of the M5 and U18t.
I made the mistake of asking for a really short cable for the M5, so I can’t currently take it out and about, but getting an extender has become priority #1. Overall the M5 has quickly and conclusively become my favourite piece of gear.
I will soon be writing up a full review, that won’t be based on so many comparisons as I’d like to avoid posting this one in other platforms and threads, but yeah, the M5 is a pure masterpiece
