After doing some a/b comparisons using the new Audio Technica AT-HDC5/1.2 cable I am simply amazed.
Cable can be found here: http://www.audio-technica.co.jp/atj/show_model.php?modelId=2418
I used the cable on both the Sony NW-ZX1 that I recently acquired and my iBasso HDP-R10.
The earphones were the IM02 and the IM03. If someone wants to send me the IM04, I would be more than happy to add it to my impressions.
With the IM03, the HDC5 cable gives it a brighter sound, with better detail. Lows are still there, but not as upfront, highs are brought out.
With the IM02, the neutral sound continues, but bass is improved. Highs get a tad more sparkly, bigger soundstage overall, and details are further brought out.
The biggest difference seems to be on the IM03, it really makes these go up another step in audio quality. The change is good on the IM02 as well, but not as drastic, you get more detail and a slightly more open sound.
With either earphone, I recommend this cable, but only if you like a bright signature, because this will make your high’s more sparkly, perhaps to sparkly for some.
If you prefer a darker soundstage, stick to the IM03, and call it a day.
Especially with the IM03, if you like a bright sound full of detail, but the better low end reproduction of the IM03, then this cable is really a must. With the IM02, the neutral sound is made slightly brighter and details are improved.
Myself, I'm keeping the cable on the IM03, and the stock on the IM02.
