Effect Audio Leonidas Pairing:

effect leonidas

Leonidas is a smooth and balanced sounding cable with an exception of the slight fullness in low frequency that results in a weightier presentation.

Leonidas makes the J6R more controlled, refined, and definitely smoother. The lows are a little more prominent and fuller compared to stock cable with a more natural tone. Hits become a bit grander and the Leonidas releases better-textured notes.

The midrange is weightier, more resolved, and thicker with the Leonidas, while the stock cable sounds messy and brighter. Vocals have more body and depth with lesser tendency to sibilance on the Leonidas. In the high frequency, Leonidas significantly betters the stock cable by making the treble presentation smoother, and more forgiving.

In terms of soundstage, the Leonidas doesn’t really change the width, but it significantly improves the background blackness and locates it more distant. In addition, the stage becomes deeper and the separation gets better.

Final Words:

Jomo 6R has an airy, technical, and neutral approach with a terrific transparency. Some may find it a bit bright in accordance with the source used, but it provides quite clear spaces around instruments. The J6R sounds great with a suitable aftermarket IEM cable and gets definitely better in terms of tonality. It can be purchased directly from Jomo Audio themselves. Its regular price is 1399 SGD (approx. $1030) with the exception of customization and package options.

  1. Hi, I’m looking for a neutral CIEM with a big soundstage. Hoping it sounds more musical than analytical, with a bit of treble sparkle. Looking at this, Perfect Seal AR6 and HUM Pristine reference. Would you recommend any of them? Thanks for your time.

    • Hi,

      Perfect Seal AR6 may be better for your needs. HUM Pristine custom version sounds a bit aggressive in terms of the stage structure. Also, you may take a look to Lear LCM-BD4.2
