So I was given the chance to demo the 1964 V6, V6S, V8, and the Noble 6C and K10 by Calvin from Music Sanctuary. He did bring along the 8C, but I kinda forgot to demo it
Do note that as I have mentioned before, my dictionary of audio terminology is extremely, extremely limited.
So here's my very brief 2-cents impressions (YMMV).
1964ears
V6
The most neutral signature in the 1964ears series. Decent bass, although as described previously in head-fi, the quantity of the bass is lacking. Vocals are and smooth and sweet, but slightly laid back, which is not a bad thing too. Perhaps I've been too spoiled by the shures, which is better for vocals. However, I like this as it allows me to focus on the instruments as well. The shures are sometimes so forward I find it alittle difficult to focus on the instruments, although in terms of pure vocals, the shures wins hands down. The highs are great, and is even better than that of the 846 with white filters.
V6 Stage
Different signature from the V6. More emphasis on bass and highs. Mids are still good, but slighter more recessed. I will like it for bassier tracks, but for general use, I'd prefer the V6 to complement my shures.
V8
My favourite of the 1964 series. Thumping base! Vocals are still sweet. Highs are brillant but not overly so, so less sibilance with my 846. If I were to replace my 846, this would be it! Awesome soundstaging. Didn't really focus on its separation, but seems to be a tad poorer than the V6, but may just be me not focusing well enough.
Noble Audio
6C
Similar to the V6, better in its own way. Bass was less impactful than the V6, but makes up with brilliant mids and highs. Seems a bit less sweet than the V6 though. Is this better than the V6? Not to me at least, due to the price difference. Didn't spend much time with this IEM though, so i would not want to comment on this much more.
K10
The clear winner here. What's been said on head-fi has been said, so there isn't anything I can add to the expert reviews by the other head-fiers. Its by far the most all rounded CIEM available in the list I have tried here. To my ears at least, once i put them on, there was no doubt. For the rest, I had to A/B multiple times before I came to my conclusion. Its an awesome IEM! Best IEM in the world? Thats subjective! I like it though, and thats good enough for me.
Please note that I tried them with my DX90 on a wide variety of tracks. This is just my humble opinion on these iems. I am by no means saying that any of these are poor/bad or worse than the other (maybe with the exception of the K10
).
Again, many thanks to Calvin from Music Sanctuary for coming all the way to Sengkang for me to demo these awesome IEMs.
